-A general purpose lookup utility that defines a mapping between X and Y as a
-continuous set of line segments with shared (x, y) end-points.
-The (x, y) points must be added in order, monotonically increasing in both x and y;
-a log warning is emitted if this does not happen (See general usage notes below).
-
-A limited history of (x, y) points is kept for space reasons (See general usage notes).
-
-In AudioFlinger, we use the LinearMap to associate track frames to
-sink frames.  When we want to obtain a client track timestamp, we first
-get a timestamp from the sink.  The sink timestamp's position (mPosition)
-corresponds to the sink frames written. We use LinearMap to figure out which track frame
-the sink frame corresponds to. This allows us to substitute a track frame for the
-the sink frame (keeping the mTime identical) and return that timestamp back to the client.
-
-The method findX() can be used to retrieve an x value from a given y value and is
-used for timestamps, similarly for findY() which is provided for completeness.
-
-We update the (track frame, sink frame) points in the LinearMap each time we write data
-to the sink by the AudioFlinger PlaybackThread (MixerThread).
-
-
-AudioFlinger Timestamp Notes:
-
-1) Example: Obtaining a track timestamp during playback.  In this case, the LinearMap
-looks something like this:
-
-Track Frame    Sink Frame
-(track start)
-0              50000  (track starts here, the sink may already be running)
-1000           51000
-2000           52000
-
-When we request a track timestamp, we call the sink getTimestamp() and get for example
-mPosition = 51020.  Using the LinearMap, we find we have played to track frame 1020.
-We substitute the sink mPosition of 51020 with the track position 1020,
-and return that timestamp to the app.
-
-2) Example: Obtaining a track timestamp duing pause. In this case, the LinearMap
-looks something like this:
-
-Track Frame    Sink Frame
-... (some time has gone by)
-15000          30000
-16000          31000
-17000          32000
-(pause here)
-(suppose we call sink getTimestamp() here and get sink mPosition = 31100; that means
-        we have played to track frame 16100.  The track timestamp mPosition will
-        continue to advance until the sink timestamp returns a value of mPosition
-        greater than 32000, corresponding to track frame 17000 when the pause was called).
-17000          33000
-17000          34000
-...
-
-3) If the track underruns, it appears as if a pause was called on that track.
-
-4) If there is an underrun in the HAL layer, then it may be possible that
-the sink getTimestamp() will return a value greater than the number of frames written
-(it should always be less). This should be rare, if not impossible by some
-HAL implementations of the sink getTimestamp. In that case, timing is lost
-and we will return the most recent track frame written.
-
-5) When called with no points in the map, findX() returns the start value (default 0).
-This is consistent with starting after a stop() or flush().
-
-6) Resuming after Track standby will be similar to coming out of pause, as the HAL ensures
-framesWritten() and getTimestamp() are contiguous for non-offloaded/direct tracks.
-
-7) LinearMap works for different speeds and sample rates as it uses
-linear interpolation. Since AudioFlinger only updates speed and sample rate
-exactly at the sample points pushed into the LinearMap, the returned values
-from findX() and findY() are accurate regardless of how many speed or sample
-rate changes are made, so long as the coordinate looked up is within the
-sample history.
-
-General usage notes:
-
-1) In order for the LinearMap to work reliably, you cannot look backwards more
-than the size of its circular buffer history, set upon creation (typically 16).
-If you look back further, the position is extrapolated either from a passed in
-extrapolation parameter or from the oldest line segment.
-
-2) Points must monotonically increase in x and y. The increment between adjacent
-points cannot be greater than signed 32 bits. Wrap in the x, y coordinates are supported,
-since we use differences in our computation.
-
-3) If the frame data is discontinuous (due to stop or flush) call reset() to clear
-the sample counter.
-
-4) If (x, y) are not strictly monotonic increasing, i.e. (x2 > x1) and (y2 > y1),
-then one or both of the inverses y = f(x) or x = g(y) may have multiple solutions.
-In that case, the most recent solution is returned by findX() or findY().  We
-do not warn if (x2 == x1) or (y2 == y1), but we do logcat warn if (x2 < x1) or
-(y2 < y1).
-
-5) Due to rounding it is possible x != findX(findY(x)) or y != findY(findX(y))
-even when the inverse exists. Nevertheless, the values should be close.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
