Class CypressFX2.AEPacketRawPool

Enclosing class:

CypressFX2

public class CypressFX2.AEPacketRawPool
extends java.lang.Object

Object that holds pool of AEPacketRaw that handles data interchange between capture and other (rendering) threads. While the capture thread (AEReader.processData) captures events into one buffer (an AEPacketRaw) the other thread (AEViewer.run()) can render the events. The only time the monitor on the pool needs to be acquired is when swapping or initializing the buffers, to prevent either referencing unrelated data or having memory change out from under you.

Method Summary

AEPacketRaw	readBuffer()
void	reset() Set the current buffer to be the first one and clear the write buffer
void	swap() swaps the read and write buffers so that the buffer that was getting written is now the one that is read from, and the one that was read from is now the one written to.
AEPacketRaw	writeBuffer()

Method Detail

swap

public final void swap()

swaps the read and write buffers so that the buffer that was getting written is now the one that is read from, and the one that was read from is now the one written to. Thread safe.

readBuffer

public final AEPacketRaw readBuffer()

Returns:

buffer that consumer reads from.

writeBuffer

public final AEPacketRaw writeBuffer()

Returns:

buffer that acquisition thread writes to.

reset

public final void reset()

Set the current buffer to be the first one and clear the write buffer
