public class Base64InputStream
extends java.io.FilterInputStream

Decodes a stream containing a MIME base64 encoded binary.

in

Constructor Summary

Base64InputStream(java.io.InputStream in)
Construct a Base64 decoder with the default buffer size.

Base64InputStream(java.io.InputStream in, int bufsz)
Construct a Base64 decoder with the specified buffer size.

Method Summary

int	read() Read a single byte from the stream.

Constructor Detail

Base64InputStream

public Base64InputStream(java.io.InputStream in)

Construct a Base64 decoder with the default buffer size. Other comments as the constructor of two parameters.

Base64InputStream

public Base64InputStream(java.io.InputStream in,
                         int bufsz)

Construct a Base64 decoder with the specified buffer size. The stream will always attempt to read the full buffer from its source. (This guarantee is useful when working with e.g. a ccs.utils.LineInputStream.)

Method Detail

read

public int read()
         throws java.io.IOException

Read a single byte from the stream. Not usually recommended.

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

read

public int read(byte[] wad,
                int off,
                int len)
         throws java.io.IOException

Reads part of an array from the stream.

Overrides:

read in class java.io.FilterInputStream

Returns:

The number of bytes actually read, or -1 for EOF.

Throws:

java.io.IOException
