oracle.security.xmlsec.transform

Class Base64Decoder

java.lang.Object

oracle.security.xmlsec.transform.XSTransformer

oracle.security.xmlsec.transform.Base64Decoder

All Implemented Interfaces:

NodeToStreamTransform

public class Base64Decoder
extends XSTransformer
implements NodeToStreamTransform

Internal use only. Applies base-64 decoding as per RFC 1421 (PEM) and RFC 2045 (MIME) as a Transform. Whitespace characters ('\r', '\n', '\t', ' ') are ignored in input.

Constructor Detail

Base64Decoder

public Base64Decoder()

Creates a new Base64Decoder instance.

Base64Decoder

public Base64Decoder(XSAlgorithmIdentifier trans)

Creates a new Base64Decoder instance.

Parameters:

trans - A XSAlgorithmIdentifier object containing no parameter element.

Throws:

java.lang.IllegalArgumentException - If the XSAlgorithmIdentifier is not a valid Base64 decode Transform.

Method Detail

getAlgorithmURI

public java.lang.String getAlgorithmURI()

Description copied from class: XSTransformer

Returns the URI string identifying the Transform algorithm.

Specified by:

getAlgorithmURI in class XSTransformer

Returns:

This Transform's URI string.

transform

public XMLContainer transform(XMLContainer source)
                       throws TransformationException

Applies a Base64 decoding transformation to the given XMLContainer and returns the octet stream result in a new XMLContainer.

Specified by:

transform in class XSTransformer

Parameters:

source - A XMLContainer on which the transform will operate.

Returns:

A XMLContainer containing the transform octet stream result.

Throws:

TransformationException - if an error occurs during the transformation process.

transformToStream

public java.io.InputStream transformToStream(NodeReader source)
                                      throws java.io.IOException,
                                             TransformationException

Description copied from interface: NodeToStreamTransform

transform method that does not actually do the transform, but only sets up things. The actual transform should be done when somebody reads from the InputStream

Specified by:

transformToStream in interface NodeToStreamTransform

Returns:

Throws:

java.io.IOException

TransformationException
