Class MemoryByteArrayOutputStream
OutputStream
org.jfree.report.util.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.
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.
|
void | close() - Close the stream, flushing it first.
|
void | flush() - Flush the stream.
|
int | getLength()
|
byte[] | getRaw()
|
byte[] | toByteArray()
|
void | write(byte[] b) - Writes
b.length bytes from the specified byte array to this output stream.
|
void | write(byte[] cbuf, int off, int len) - Write a portion of an array of characters.
|
void | write(int b) - Writes the specified byte to this output stream.

MemoryByteArrayOutputStream
public MemoryByteArrayOutputStream()
Create a new character-stream writer whose critical sections will synchronize on the writer itself.
MemoryByteArrayOutputStream
public MemoryByteArrayOutputStream(int bufferSize,
int maximumBufferIncrement)
Create a new character-stream writer whose critical sections will synchronize on the writer itself.
close
public void close()
throws IOException
Close the stream, flushing it first. Once a stream has been closed, further write() or flush() invocations will
cause an IOException to be thrown. Closing a previously-closed stream, however, has no effect.
flush
public void flush()
throws IOException
Flush the stream. If the stream has saved any characters from the various write() methods in a buffer, write them
immediately to their intended destination. Then, if that destination is another character or byte stream, flush
it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams.
If the intended destination of this stream is an abstraction provided by the underlying operating system, for
example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to
the operating system for writing; it does not guarantee that they are actually written to a physical device such as
a disk drive.
write
public void write(byte[] b)
throws IOException
Writes 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)
.
java.io.OutputStream.write(byte[], int, int)
write
public void write(byte[] cbuf,
int off,
int len)
throws IOException
Write a portion of an array of characters.
cbuf
- Array of charactersoff
- Offset from which to start writing characterslen
- Number of characters to write
write
public void write(int b)
throws IOException
Writes the specified byte to this output stream. The general contract for
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.
