Class FilterOutputStream

public class FilterOutputStream extends OutputStream

This class is the common superclass of output stream classes that filter the output they write. These classes typically transform the data in some way prior to writing it out to another underlying OutputStream. This class simply overrides all the methods in OutputStream to redirect them to the underlying stream. Subclasses provide actual filtering.

Field Summary
protected OutputStream	out This is the subordinate `OutputStream` that this class redirects its method calls to.

Constructor Summary
	FilterOutputStream(OutputStream out) This method initializes an instance of `FilterOutputStream` to write to the specified subordinate `OutputStream`.

Method Summary
void	close() This method closes the underlying `OutputStream`.
void	flush() This method attempt to flush all buffered output to be written to the underlying output sink.
void	write(int b) This method writes a single byte of output to the underlying `OutputStream`.
void	write(byte[] buf) This method writes all the bytes in the specified array to the underlying `OutputStream`.
void	write(byte[] buf, int offset, int len) This method calls the `write(int)` method `len` times for all bytes from the array `buf` starting at index `offset`.
