Overrides:

canRead in class StreamImpl

getAvailable

public int getAvailable()
                 throws java.io.IOException

Description copied from class: StreamImpl

Overrides:

getAvailable in class StreamImpl

Throws:

java.io.IOException

read

public int read(byte[] buffer,
                int offset,

         throws java.io.IOException

Description copied from class: StreamImpl

Reads the next chunk from the stream.

Overrides:

read in class StreamImpl

Parameters:

buffer - byte array receiving the data.

offset - starting offset into the array.

length - number of bytes to read.

Returns:

the number of bytes read or -1 on end of file.

Throws:

java.io.IOException

canWrite

public boolean canWrite()

Description copied from class: StreamImpl

Returns true if this is a writable stream.
