This class handles how bytes should be read in from TCP Socket Most of the time, a reader will not need to implement this class and can instead use either the GenericByteStreamReader or the GenericCharStreamReader. If it does need this method, this class will need to implement the AbstractStreamReader interface

read

This method should read in bytes from the TCP socket

public abstract byte[] read() throws IOException;

Arguments

Return Value

bytes that were read

Reference Implementation

This is the implementation of the read method in the GenericByteStreamReader.

	public byte[] read() throws IOException {
		ArrayList<Byte> bytes = new ArrayList<Byte>();
		int b = in.read();
		while (in.available() != 0) {
			bytes.add((byte) b);
			b = in.read();
		}
		bytes.add((byte)b);
		/* If there is nothing on the buffer, return null */
		if (bytes.isEmpty() || bytes.get(0)==-1) {
			logger.debug("returning bytes is null");
			return null;
		}
		/* Else return the bytes */
		else {
			byte[] retVal = new byte[bytes.size()];

			logger.debug("returning bytes");
			for (int i = 0; i < bytes.size(); i++) {
				retVal[i] = bytes.get(i);
			}
			return retVal;
		}
