Method Detail

tryCleanDirectByteBuffer

public void tryCleanDirectByteBuffer(java.nio.ByteBuffer byteBuffer)

DirectByteBuffers are garbage collected by using a phantom reference and a reference queue. Every once a while, the JVM checks the reference queue and cleans the DirectByteBuffers. However, as this doesn't happen immediately after discarding all references to a DirectByteBuffer, it's easy to OutOfMemoryError yourself using DirectByteBuffers. This function explicitly calls the Cleaner method of a DirectByteBuffer.

Utilizes reflection to avoid dependency to sun.misc.Cleaner.

Parameters:

byteBuffer - (undocumented)
