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 );

Closes this object and deallocates the appropriate resources.
The object is generally no longer usable after calling close.

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.
Implements decaf::io::Reader.
virtual bool decaf::io::InputStreamReader::ready |
( |
| ) |
const |
|

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.
