doRead
@Deprecated int doRead(ByteChunk chunk) throws IOException
Deprecated.Unused. Will be removed in Tomcat 9. UsedoRead(ApplicationBufferHandler)Read from the input stream into the given buffer. IMPORTANT: the current model assumes that the protocol will 'own' the buffer and return a pointer to it in ByteChunk (i.e. the param will have chunk.getBytes()==null before call, and the result after the call).- Parameters:
chunk- 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
-
doRead
int doRead(ApplicationBufferHandler handler) throws IOException
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.- 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
-
available
int available()
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.- Returns:
- The number of bytes that can be read without blocking
