Method Detail

getUpdateThreadData

final J3dThreadData getUpdateThreadData()

This returns the thread data for this thread.

addMessage

final void addMessage(J3dMessage message)

This adds a message to the list of messages for this structure

getMessages

final J3dMessage[] getMessages(long referenceTime)

This returns whether or not there are any pending messages

clearMessages

final void clearMessages()
