Parameters:

buffer - the backing byte buffer.

Method Detail

close

public void close()
           throws IOException

Close this output stream and releases any system resources associated with it.

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException - if an I/O error occurs.

See Also:

OutputStream.close()

flush

public void flush()
           throws IOException

Flushes this output stream and force any buffered output bytes to be written out.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException - if an I/O error occurs.

See Also:

OutputStream.flush()

write

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

Write len bytes from the specified byte array starting at offset off to this output stream.

Overrides:

write in class OutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

IOException - if an I/O error occurs.

See Also:

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

write

public void write(byte[] b)
           throws IOException

Writes b.length bytes from the specified byte array to this output stream.

Overrides:

write in class OutputStream

Parameters:

b - the data.

Throws:

IOException - if an I/O error occurs.

See Also:

OutputStream.write(byte[])

write

public void write(int b)
           throws IOException

Writes the specified byte to this output stream.

Specified by:

write in class OutputStream

Parameters:

b - the byte.

Throws:

IOException - if an I/O error occurs.

See Also:

OutputStream.write(int)

toByteBuffer

public ByteBuffer toByteBuffer()
