Inheritance diagram for decaf::io::ByteArrayOutputStream:

Public Member Functions
	ByteArrayOutputStream ()
	Default Constructor - uses a default internal buffer of 32 bytes, the size increases as the need for more room arises.
	ByteArrayOutputStream (int bufferSize)
	Creates a ByteArrayOutputStream with an internal buffer allocated with the given size.
virtual	~ByteArrayOutputStream ()
std::pair< unsigned char *, int >	toByteArray () const
	Creates a newly allocated byte array.
long long	size () const
	Gets the current count of bytes written into this ByteArrayOutputStream.
virtual void	reset ()
	Clear current Stream contents.
virtual std::string	toString () const
	Converts the bytes in the buffer into a standard C++ string.
void	writeTo (OutputStream *out) const
	Writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream's write method using out.write( buf, 0, count ).
Public Member Functions inherited from decaf::io::OutputStream
	OutputStream ()
virtual	~OutputStream ()
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.
virtual void	flush ()
	Flushes this stream by writing any buffered output to the underlying stream. Exceptions IOException if an I/O error occurs.
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.
virtual void	wait (long long millisecs, int nanos)
	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.
virtual void	notifyAll ()
	Signals the waiters on this object that it can now wake up and continue.

Constructor & Destructor Documentation

decaf::io::ByteArrayOutputStream::ByteArrayOutputStream

(

)

Default Constructor - uses a default internal buffer of 32 bytes, the size increases as the need for more room arises.

decaf::io::ByteArrayOutputStream::ByteArrayOutputStream

(

int

bufferSize

)

Creates a ByteArrayOutputStream with an internal buffer allocated with the given size.

Parameters

bufferSize

The size to use for the internal buffer.

Exceptions

IllegalArgumentException

if the size is less than or equal to zero.

virtual decaf::io::ByteArrayOutputStream::~ByteArrayOutputStream ( )

virtual

Member Function Documentation

virtual void decaf::io::ByteArrayOutputStream::doWriteArrayBounded ( const unsigned char *  buffer, int  size, int  offset, int  length  )

protectedvirtual

Reimplemented from decaf::io::OutputStream.

virtual void decaf::io::ByteArrayOutputStream::doWriteByte ( unsigned char  value )

protectedvirtual

Implements decaf::io::OutputStream.

virtual void decaf::io::ByteArrayOutputStream::reset ( )

virtual

Clear current Stream contents.

Exceptions

IOException

long long decaf::io::ByteArrayOutputStream::size

(

)

const

Gets the current count of bytes written into this ByteArrayOutputStream.

Returns

the number of valid bytes contained in the ByteArrayOutputStream.

std::pair<unsigned char*, int> decaf::io::ByteArrayOutputStream::toByteArray

(

)

const

Creates a newly allocated byte array.

Its size is the current size of this output stream and the valid contents of the buffer have been copied into it. The newly allocated array and its size are returned inside an STL pair structure, the caller is responsible for freeing the returned array.

Returns

an STL pair containing the copied array and its size.

virtual std::string decaf::io::ByteArrayOutputStream::toString ( ) const

virtual

Converts the bytes in the buffer into a standard C++ string.

Returns

a string containing the bytes in the buffer

Reimplemented from decaf::io::OutputStream.

void decaf::io::ByteArrayOutputStream::writeTo

(

OutputStream *

out

)

const

Writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream's write method using out.write( buf, 0, count ).
