Method Details- 
doReadDescription copied from interface:InputBufferRead from the input stream into the ByteBuffer provided by the ApplicationBufferHandler. IMPORTANT: the current model assumes that the protocol will 'own' the ByteBuffer and return a pointer to it.- Specified by:
- doReadin interface- InputBuffer
- Parameters:
- handler- ApplicationBufferHandler that provides the buffer to read data into.
- Returns:
- The number of bytes that have been added to the buffer or -1 for end of stream
- Throws:
- IOException- If an I/O error occurs reading from the input stream
 
- 
availablepublic int available()Description copied from interface:InputBufferObtain an estimate of the number of bytes that can be read without blocking. Typically, this will be the number of available bytes known to be buffered.- Specified by:
- availablein interface- InputBuffer
- Returns:
- The number of bytes that can be read without blocking
 
- 
fillHeaderBufferDescription copied from interface:HttpHeaderParser.HeaderDataSourceRead more data into the header buffer. The implementation is expected to determine if blocking or not blocking IO should be used.- Specified by:
- fillHeaderBufferin interface- HttpHeaderParser.HeaderDataSource
- Returns:
- trueif more data was added to the buffer, otherwise- false
- Throws:
- IOException- If an I/O error occurred while obtaining more header data
 
- 
setByteBufferDescription copied from interface:ApplicationBufferHandlerSet the byte buffer.- Specified by:
- setByteBufferin interface- ApplicationBufferHandler
- Parameters:
- buffer- the byte buffer
 
- 
getByteBuffer- Specified by:
- getByteBufferin interface- ApplicationBufferHandler
- Returns:
- the byte buffer
 
- 
getHeaderByteBufferDescription copied from interface:HttpHeaderParser.HeaderDataSourceObtain a reference to the buffer containing the header data.- Specified by:
- getHeaderByteBufferin interface- HttpHeaderParser.HeaderDataSource
- Returns:
- The buffer containing the header data
 
- 
expandpublic void expand(int size) Description copied from interface:ApplicationBufferHandlerExpand the byte buffer to at least the given size. Some implementations may not implement this.- Specified by:
- expandin interface- ApplicationBufferHandler
- Parameters:
- size- the desired size
