getBindingURI

public java.lang.String getBindingURI()

Gets the SAML binding URI supported by this decoder.

Specified by:

getBindingURI in interface SAMLMessageDecoder

Returns:

SAML binding URI supported by this decoder

doDecode

protected void doDecode()
                 throws MessageDecodingException

Performs the decoding logic. By the time this is called, this decoder has already been initialized and checked to ensure that it has not been destroyed.

Specified by:

doDecode in class AbstractMessageDecoder<SAMLObject>

Throws:

MessageDecodingException - thrown if there is a problem decoding the message

decodeMessage

protected java.io.InputStream decodeMessage(java.lang.String message)
                                     throws MessageDecodingException

Base64 decodes the SAML message and then decompresses the message.

Parameters:

message - Base64 encoded, DEFALTE compressed, SAML message

Returns:

the SAML message

Throws:

MessageDecodingException - thrown if the message can not be decoded

populateBindingContext

protected void populateBindingContext(MessageContext<SAMLObject> messageContext)

Populate the context which carries information specific to this binding.

Parameters:

messageContext - the current message context
