Constructor Detail

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.

Method Detail

write

public void write(byte[] cbuf,
         int off,
         int len)
           throws IOException

Write a portion of an array of characters.

Overrides:

write in class OutputStream

Parameters:

cbuf - Array of characters

off - Offset from which to start writing characters

len - Number of characters to write

Throws:

IOException - If an I/O error occurs

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).

Overrides:

write in class OutputStream

Parameters:

b - the data.

Throws:

IOException - if an I/O error occurs.

See Also:

OutputStream.write(byte[], int, int)

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.

Specified by:

write in class OutputStream

Parameters:

b - the byte.

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

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.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException - If an I/O error occurs

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.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class OutputStream

Throws:

IOException - If an I/O error occurs

toByteArray

public byte[] toByteArray()

getLength

public int getLength()

getRaw

public byte[] getRaw()
