public class BufferedOutputSource

extends Object

The OutputSource class writes byte wise data into a buffer. If the buffer is full the data is appended to a StringBuffer. This is done due to performance reasons.

Field Summary

protected byte[]	buffer byte array to write the bytes in.
protected int	bufferIndex the index of the byte array buffer
protected int	index the index of the output source

Constructor Summary

BufferedOutputSource()
Constructor with no additional method calls.

Method Summary

protected void	fillStringBuffer() fills the internal StringBuffer with the bytes from the byte array ('internal cache' buffer to speed up the performance)
byte[]	getBuffer() gets the 'internal cache' (buffer) of this BufferedOutputSource object
int	getBufferIndex() gets the index of the 'internal cache' (bufferIndex)
int	getIndex() gets the index of this BufferedOutputSource object
StringBuffer	getStringBuffer() returns the complete content of this BufferedOutputSource object.
void	reset() resets this BufferedOutputSource object (empties all buffers)
String	toString() returns the complete content of this BufferedOutputSource object.
void	writeByte(byte byteToAdd) writes the given byte into this BufferedOutputSource instance
void	writeByte(char charToAdd) writes the given char into this BufferedOutputSource instance
void	writeSource(BufferedOutputSource outputSource) writes the content of the given BufferedOutputSource object into this BufferedOutputSource instance

Field Detail

buffer

protected byte[] buffer

byte array to write the bytes in. It is the 'internal cache' to speed up the performance. If a certain quantity is reached, the content is moved into the 'main' StringBuffer.

bufferIndex

protected int bufferIndex

the index of the byte array buffer

index

protected int index

the index of the output source

Constructor Detail

BufferedOutputSource

public BufferedOutputSource()

Constructor with no additional method calls.

Method Detail

fillStringBuffer

protected void fillStringBuffer()

fills the internal StringBuffer with the bytes from the byte array ('internal cache' buffer to speed up the performance)

writeSource

public void writeSource(BufferedOutputSource outputSource)

writes the content of the given BufferedOutputSource object into this BufferedOutputSource instance
