public interface StateTransistor

StateTransistor is an interface with the functionality of performing the actual state transitions: DoPrefetch, DoRealize, etc.

方法摘要

void	abortRealize() Called when the realize() is aborted, i.e. deallocate() was called while realizing.
void	doClose() This function performs the steps to close a module or Player.
void	doDealloc() This function performs the steps to deallocate a module or Player, and return to the realized state.
void	doFailedPrefetch() Called when prefetch fails.
void	doFailedRealize() Called when realize fails.
boolean	doPrefetch() This function performs the steps to prefetch a module or Player.
boolean	doRealize() This function performs the steps of realizing a module or a Player.
void	doSetMediaTime(Time t) This function notifies the module that the media time has changed.
float	doSetRate(float r) This function notifies the module that the playback rate has changed.
void	doStart() This function performs the steps to start a module or Player.
void	doStop() This function performs the steps to stop a module or Player, and return to the prefetched state.

方法详细信息

doRealize

boolean doRealize()

This function performs the steps of realizing a module or a Player.

返回：

true if successful.

doFailedRealize

void doFailedRealize()

Called when realize fails.

abortRealize

void abortRealize()

Called when the realize() is aborted, i.e. deallocate() was called while realizing. Release all resources claimed previously by the realize() call.

doPrefetch

boolean doPrefetch()

This function performs the steps to prefetch a module or Player.

返回：

true if successful.

doFailedPrefetch

void doFailedPrefetch()

Called when prefetch fails.

abortPrefetch

void abortPrefetch()

Called when the prefetch() is aborted, i.e. deallocate() was called while prefetching. Release all resources claimed previously by the prefetch call.

doStart

void doStart()

This function performs the steps to start a module or Player.

doStop

void doStop()

This function performs the steps to stop a module or Player, and return to the prefetched state.

doDealloc

void doDealloc()

This function performs the steps to deallocate a module or Player, and return to the realized state.

doClose

void doClose()

This function performs the steps to close a module or Player.

doSetMediaTime

void doSetMediaTime(Time t)

This function notifies the module that the media time has changed.

doSetRate

float doSetRate(float r)

This function notifies the module that the playback rate has changed.
