inlinevirtual

Input multiple bytes for processing on a channel.

Parameters

channel	the channel to process the data.
begin	the byte buffer to process.
length	the size of the string, in bytes.
messageEnd	means how many filters to signal MessageEnd() to, including this one.
blocking	specifies whether the object should block when processing input.

Returns: the number of bytes that remain to be processed (i.e., bytes not processed)
