Method Detail

rawAvailable

public int rawAvailable()
                 throws java.io.IOException

Description copied from class: SystemInputStream

This method should be overridden by subclassing InputStreams. It returns the amount available from the underlying root stream. This is not the amount available if the SystemInputStream is not in raw mode.

Overrides:

rawAvailable in class SystemInputStream

Returns:

amount of data available directly from the underlying stream

Throws:

java.io.IOException - if an error occurs in the underlying stream.

SystemInputStream.setRawMode(boolean), SystemInputStream.rawRead(), SystemInputStream.rawRead(byte[],int,int)

rawRead

protected int rawRead()
               throws java.io.IOException

Read the next character from the stream. This should only be called from within a synchronized block.

Overrides:

rawRead in class SystemInputStream

Returns:

the next character from the stream, or -1 if the end of the stream has been reached.

Throws:

java.io.IOException - if an IO problem occurs during the read.
