Assign the keyFrame (specified by index) a time value and an array of key
values and blend array.

Assign the keyFrame (specified by index) a time value and an array of key
values (with an implicity blend array of [0, 0, 1, 1] giving linear
transition to the next set of key values).

Set a repeat count (which may be fractional) for the interpolator, and
whether the interpolator should mirror its repeats.

Calls timeToValues(msec, values) with the msec set to now (by calling

Given a millisecond time value (msec), return the interpolated values and
return whether the specified time was within the range of key times
(NORMAL), was before the first key time (FREEZE_START) or after the last
key time (FREEZE_END).

Reset the Interpolator to have the specified number of values and an implicit keyFrame count of 2 (just a start and end). After this call the values for each keyFrame must be assigned using setKeyFrame().

Assign the keyFrame (specified by index) a time value and an array of key values and blend array.
| index | The index of the key frame to assign |
|---|---|
| msec | The time (in mililiseconds) for this key frame. Based on the SystemClock.uptimeMillis() clock |
| values | Array of values associated with theis key frame |
| blend | (may be null) Optional array of 4 blend values |

Set a repeat count (which may be fractional) for the interpolator, and whether the interpolator should mirror its repeats. The default settings are repeatCount = 1, and mirror = false.
Calls timeToValues(msec, values) with the msec set to now (by calling (int)SystemClock.uptimeMillis().)
Given a millisecond time value (msec), return the interpolated values and return whether the specified time was within the range of key times (NORMAL), was before the first key time (FREEZE_START) or after the last key time (FREEZE_END). In any event, computed values are always returned.
| msec | The time (in milliseconds) used to sample into the Interpolator. Based on the SystemClock.uptimeMillis() clock |
|---|---|
| values | Where to write the computed values (may be NULL). |
Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.
Note that objects that override finalize are significantly more expensive than
objects that don't. Finalizers may be run a long time after the object is no longer
reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup.
Note also that finalizers are run on a single VM-wide finalizer thread,
so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary
for a class that has a native peer and needs to call a native method to destroy that peer.
Even then, it's better to provide an explicit close method (and implement
Closeable), and insist that callers manually dispose of instances. This
works well for something like files, but less well for something like a BigInteger
where typical calling code would have to deal with lots of temporaries. Unfortunately,
code that creates lots of temporaries is the worst kind of code from the point of view of
the single finalizer thread.
If you must use finalizers, consider at least providing your own
ReferenceQueue and having your own thread process that queue.
Unlike constructors, finalizers are not automatically chained. You are responsible for
calling super.finalize() yourself.
Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
