org.jfree.report.util.MemoryByteArrayOutputStream
public class MemoryByteArrayOutputStream
A string writer that is able to write large amounts of data. The original StringWriter contained in Java doubles its buffersize everytime the buffer overflows. This is nice with small amounts of data, but awfull for huge buffers.
Constructor Summary | |
---|---|
MemoryByteArrayOutputStream()
Create a new character-stream writer whose critical sections will synchronize on the writer itself. |
|
MemoryByteArrayOutputStream(int bufferSize,
int maximumBufferIncrement)
Create a new character-stream writer whose critical sections will synchronize on the writer itself. |

public void write(byte[] cbuf, int off, int len) throws java.io.IOException
write
in class java.io.OutputStream
cbuf
- Array of charactersoff
- Offset from which to start writing characterslen
- Number of characters to write
java.io.IOException
- If an I/O error occurspublic void write(byte[] b) throws java.io.IOException
b.length
bytes from the specified byte array to this output stream. The general contract for
write(b)
is that it should have exactly the same effect as the call write(b, 0,
b.length)
.

b
- the data.
java.io.IOException
- if an I/O error occurs.OutputStream.write(byte[], int, int)
public void write(int b) throws java.io.IOException
write
is that one byte is
written to the output stream. The byte to be written is the eight low-order bits of the argument b
.
The 24 high-order bits of b
are ignored.
Subclasses of OutputStream
must provide an implementation for this method.
