Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default void`	`onFlush()`	Called when the `GlShaderProgram` has been flushed.

`default void`	`onReadyToAcceptInputFrame()`	Called when the `GlShaderProgram` is ready to accept another input frame.

- Method Detail
  - onReadyToAcceptInputFrame
```
default void onReadyToAcceptInputFrame()
```
    Called when the GlShaderProgram is ready to accept another input frame.
    For each time this method is called, GlShaderProgram.queueInputFrame(GlTextureInfo, long) can be called once.
  - onInputFrameProcessed
```
default void onInputFrameProcessed(GlTextureInfo inputTexture)
```
    Called when the GlShaderProgram has processed an input frame.
    The implementation shall not assume the GlShaderProgram is ready to accept another input frame when this method is called.
    
    Parameters:
    
    inputTexture - The GlTextureInfo that was used to queue the input frame.
  - onFlush
```
default void onFlush()
```
    Called when the GlShaderProgram has been flushed.
    The implementation shall not assume the GlShaderProgram is ready to accept another input frame when this method is called.
