Method Detail

isNeedWrite

boolean isNeedWrite()

returns whether writeMore should be called write additional data.

Returns:

is a additional write needed

writeMore

void writeMore()
        throws java.io.IOException

Gets called when isNeedWrite() ()} requires a additional rite

Throws:

java.io.IOException - may be thrown due to an error while writing

isNeedRead

boolean isNeedRead()

returns whether readMore should be called to fetch data which has been decoded but not yet been returned.

Returns:

is a additional read needed

See Also:

ReadableByteChannel.read(ByteBuffer), readMore(ByteBuffer)

readMore

int readMore(java.nio.ByteBuffer dst)
      throws java.io.IOException

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).

Parameters:

dst - the destiny of the read

Returns:

the amount of remaining data

Throws:

java.io.IOException - when a error occurred during unwrapping

isBlocking

boolean isBlocking()

This function returns the blocking state of the channel

Returns:

is the channel blocking
