iaik.smime.BoundaryBase64InputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class BoundaryBase64InputStream
extends Base64InputStream

A stream for decoding the base64 encoded data of a MIME part.

The data is read and decoded until the underlying stream is entirely read or the boundary line is reached indicating the end of the MIME part.

Constructor Detail

BoundaryBase64InputStream

public BoundaryBase64InputStream(java.io.InputStream is,
                                 java.lang.String boundary)
                          throws java.io.IOException

Creates a new BoundaryBase64InputStream to read data from the specified input stream.

Parameters:

is - the underlying input stream

boundary - the boundary of the MIME part

Throws:

java.io.IOException - if an I/O error occurs during reading from the stream

Method Detail

notify

protected void notify(byte[] buffer)
               throws java.io.IOException

Called by super class if a '-' shall be decoded.

Overrides:

notify in class Base64InputStream

Parameters:

buffer - the characters already read from the input stream; and the first one was marked with NOTIFY

Throws:

java.io.IOException - allows the subclass to throw an Exception if an error occurs

read

public int read()
         throws java.io.IOException

Reads the next byte of data from this input stream.

Overrides:

read in class Base64InputStream

Returns:

the next byte of data, or -1 if the end of the stream is reached

Throws:

java.io.IOException - if an I/O error occurs

read

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

Reads up to len bytes of data from this input stream into an array of bytes.

Overrides:

read in class Base64InputStream

Parameters:

b - the buffer into which the data is read

off - the start offset of the data

len - the maximum number of bytes read

Returns:

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached

Throws:

java.io.IOException - if an I/O error occurs

available

public int available()
              throws java.io.IOException

Returns the number of bytes that can be read from this input stream without blocking.

Overrides:

available in class java.io.FilterInputStream

Returns:

the number of bytes that can be read from the input stream without blocking

Throws:

java.io.IOException - if an I/O error occurs
