	FilterOutputStream (OutputStream *outputStream, bool own=false)
	Constructor, creates a wrapped output stream.
virtual	~FilterOutputStream ()
virtual void	flush ()
	Flushes this stream by writing any buffered output to the underlying stream. Exceptions IOException if an I/O error occurs. The default implementation of this method does nothing.
virtual void	close ()
	Closes this object and deallocates the appropriate resources.The object is generally no longer usable after calling close. Exceptions IOException if an error occurs while closing. The default implementation of this method does nothing.
virtual std::string	toString () const
	Output a String representation of this object.The default version of this method just prints the Class Name. Returns a string representation of the object.

	OutputStream ()
virtual	~OutputStream ()
virtual void	write (unsigned char c)
	Writes a single byte to the output stream.
virtual void	write (const unsigned char *buffer, int size)
	Writes an array of bytes to the output stream.
virtual void	write (const unsigned char *buffer, int size, int offset, int length)
	Writes an array of bytes to the output stream in order starting at buffer[offset] and proceeding until the number of bytes specified by the length argument are written or an error occurs.
virtual void	lock ()
	Locks the object.
virtual bool	tryLock ()
	Attempts to Lock the object, if the lock is already held by another thread than this method returns false.
virtual void	unlock ()
	Unlocks the object.
virtual void	wait ()
	Waits on a signal from this object, which is generated by a call to Notify.
virtual void	wait (long long millisecs)
	Waits on a signal from this object, which is generated by a call to Notify.

	Waits on a signal from this object, which is generated by a call to Notify.
virtual void	notify ()
	Signals a waiter on this object that it can now wake up and continue.

Detailed Description

An implementation of a FilterOutputStream that will maintain a Checksum of the bytes written, the Checksum can then be used to verify the integrity of the output stream.

Constructor & Destructor Documentation

decaf::util::zip::CheckedOutputStream::CheckedOutputStream	(	decaf::io::OutputStream *	outputStream,
		Checksum *	sum,
		bool	own = false
	)

Create a new instance of a CheckedOutputStream.

Parameters

outputStream	The OutputStream instance to Wrap.
sum	The Checksum instance to use (does not take ownership of the Pointer).
own	Indicates if this filer should take ownership of the InputStream.

Exceptions

NullPointerException

if the Checksum pointer is NULL.
