Method Detail

setFlushMethod

public static void setFlushMethod(XMPPInputOutputStream.FlushMethod flushMethod)

Set the used flushed method when compressing data. The default is full flush which may not achieve the best compression ratio, but provides better security against certain attacks. Only use sync flush if you fully understand the implications.

Parameters:
