Called by the garbage collector on an object when garbage collection
determines that there are no more references to the object.

void |
reset(int valueCount)
Reset the Interpolator to have the specified number of values and an
implicit keyFrame count of 2 (just a start and end).
|
void |
reset(int valueCount,
int frameCount)
Reset the Interpolator to have the specified number of values and
keyFrames.
|
void |
setKeyFrame(int index,
int msec,
float[] values)
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).
|
void |
setKeyFrame(int index,
int msec,
float[] values,
float[] blend)
Assign the keyFrame (specified by index) a time value and an array of key
values and blend array.
|
void |
setRepeatMirror(float repeatCount,
boolean mirror)
Set a repeat count (which may be fractional) for the interpolator, and
whether the interpolator should mirror its repeats.
|
Interpolator.Result |
timeToValues(float[] values)
Calls timeToValues(msec, values) with the msec set to now (by calling
(int)SystemClock.uptimeMillis().)
|
Interpolator.Result |
timeToValues(int msec,
float[] values)
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).

Object
finalize
method to dispose of
system resources or to perform other cleanup.
The general contract of finalize
is that it is invoked
if and when the JavaTM virtual
machine has determined that there is no longer any
means by which this object can be accessed by any thread that has
not yet died, except as a result of an action taken by the
finalization of some other object or class which is ready to be
finalized. The finalize
method may take any action, including
making this object available again to other threads; the usual purpose
of finalize
, however, is to perform cleanup actions before
the object is irrevocably discarded. For example, the finalize method
for an object that represents an input/output connection might perform
explicit I/O transactions to break the connection before the object is
permanently discarded.
The finalize
method of class Object
performs no
special action; it simply returns normally. Subclasses of
Object
may override this definition.
The Java programming language does not guarantee which thread will
invoke the finalize
method for any given object. It is
guaranteed, however, that the thread that invokes finalize will not
be holding any user-visible synchronization locks when finalize is
invoked. If an uncaught exception is thrown by the finalize method,
the exception is ignored and finalization of that object terminates.
After the finalize
method has been invoked for an object, no
further action is taken until the Java virtual machine has again
determined that there is no longer any means by which this object can
be accessed by any thread that has not yet died, including possible
actions by other objects or classes which are ready to be finalized,
at which point the object may be discarded.
The finalize
method is never invoked more than once by a Java
virtual machine for any given object.
Any exception thrown by the finalize
method causes
the finalization of this object to be halted, but is otherwise
ignored.
