readMore

public int readMore(java.nio.ByteBuffer dst)
             throws javax.net.ssl.SSLException

Description copied from interface: WrappedByteChannel

This function does not read data from the underlying channel at all. It is just a way to fetch data which has already be received or decoded but was but was not yet returned to the user. This could be the case when the decoded data did not fit into the buffer the user passed to ReadableByteChannel.read(ByteBuffer).

Specified by:

readMore in interface WrappedByteChannel

Throws:

javax.net.ssl.SSLException

isBlocking

public boolean isBlocking()

Specified by:

isBlocking in interface WrappedByteChannel
