Method Detail

available

public int available()
              throws IOException

This method returns the number of bytes available in the underlying stream divided by two. This is often less than the total number of bytes that can be read from the stream.

Overrides:

available in class InputStreamProxy

Returns:

The number of bytes available in the underlying stream divided by two.

Throws:

IOException

read

public int read()
         throws IOException

Read the next byte.

Overrides:

read in class InputStreamProxy

Throws:

IOException

read

public int read(byte[] barr)
         throws IOException

Overrides:

read in class InputStreamProxy

Throws:

IOException

read

public int read(byte[] barr,
                int off,
                int len)
         throws IOException

Overrides:
