doRead
public int doRead(ApplicationBufferHandler handler) throws java.io.IOException
Description copied from interface:InputBuffer
Read 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:
doRead
in interfaceInputBuffer
- 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:
java.io.IOException
- If an I/O error occurs reading from the input stream
-
available
public int available()
Description copied from interface:InputBuffer
Obtain 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:
available
in interfaceInputBuffer
- Returns:
- The number of bytes that can be read without blocking
-
setByteBuffer
public void setByteBuffer(java.nio.ByteBuffer buffer)
Description copied from interface:ApplicationBufferHandler
Set the byte buffer.- Specified by:
setByteBuffer
in interfaceApplicationBufferHandler
- Parameters:
buffer
- the byte buffer
-
getByteBuffer
public java.nio.ByteBuffer getByteBuffer()
- Specified by:
getByteBuffer
in interfaceApplicationBufferHandler
- Returns:
- the byte buffer
-
expand
public void expand(int size)
Description copied from interface:ApplicationBufferHandler
Expand the byte buffer to at least the given size. Some implementations may not implement this.- Specified by:
expand
in interfaceApplicationBufferHandler
- Parameters:
size
- the desired size
