Detailed Description

An InputStreamReader is a bridge from byte streams to character streams.

For top efficiency, consider wrapping an InputStreamReader within a BufferedReader. For example:

BufferedReader* in = new BufferedReader( new InputStreamReader( System.in, false ), true );

Constructor & Destructor Documentation

decaf::io::InputStreamReader::InputStreamReader	(	InputStream *	stream,
		bool	own = `false`
	)

Create a new InputStreamReader that wraps the given InputStream.

Parameters

stream	The InputStream to read from. (cannot be null).
own	Does this object own the passed InputStream (defaults to false).

Exceptions

NullPointerException if the passed InputStream is NULL.

virtual decaf::io::InputStreamReader::~InputStreamReader ( )

virtual

virtual void decaf::io::InputStreamReader::checkClosed ( ) const

protectedvirtual

virtual void decaf::io::InputStreamReader::close ( )

virtual

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 int decaf::io::InputStreamReader::doReadArrayBounded	(	char *	buffer,
		int	size,
		int	offset,
		int	length
	)

protectedvirtual

Override this method to customize the functionality of the method read( unsigned char* buffer, int size, int offset, int length ).

All subclasses must override this method to provide the basic Reader functionality.

virtual bool decaf::io::InputStreamReader::ready ( ) const

virtual

Tells whether this stream is ready to be read.

Returns: True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block.

Exceptions

IOException if an I/O error occurs.
