public class HTTPRedirectDeflateDecoder
extends BaseSAML2MessageDecoder

SAML 2.0 HTTP Redirect decoder using the DEFLATE encoding method. This decoder only supports DEFLATE compression.

HTTPRedirectDeflateDecoder()
Constructor.

HTTPRedirectDeflateDecoder(org.opensaml.xml.parse.ParserPool pool)
Constructor.

Method Summary

protected java.io.InputStream	decodeMessage(java.lang.String message) Base64 decodes the SAML message and then decompresses the message.
protected void	doDecode(org.opensaml.ws.message.MessageContext messageContext)
java.lang.String	getBindingURI() Gets the SAML binding URI supported by this decoder.
protected boolean	isIntendedDestinationEndpointURIRequired(SAMLMessageContext samlMsgCtx) Determine whether the binding implemented by the decoder requires the presence within the message of information indicating the intended message destination endpoint URI.
protected boolean	isMessageSigned(SAMLMessageContext messageContext) Determine whether the SAML message represented by the message context is digitally signed.

Constructor Detail

HTTPRedirectDeflateDecoder

public HTTPRedirectDeflateDecoder()

Constructor.

HTTPRedirectDeflateDecoder

public HTTPRedirectDeflateDecoder(org.opensaml.xml.parse.ParserPool pool)

Constructor.

Parameters:

pool - parser pool used to deserialize messages

Method Detail

getBindingURI

public java.lang.String getBindingURI()

Gets the SAML binding URI supported by this decoder.

Returns:

SAML binding URI supported by this decoder

isIntendedDestinationEndpointURIRequired

protected boolean isIntendedDestinationEndpointURIRequired(SAMLMessageContext samlMsgCtx)

Determine whether the binding implemented by the decoder requires the presence within the message of information indicating the intended message destination endpoint URI.

Specified by:

isIntendedDestinationEndpointURIRequired in class BaseSAMLMessageDecoder

Parameters:

samlMsgCtx - current SAML message context

Returns:

true if the intended message destination endpoint is required, false if not

doDecode

protected void doDecode(org.opensaml.ws.message.MessageContext messageContext)
                 throws org.opensaml.ws.message.decoder.MessageDecodingException

Specified by:

doDecode in class org.opensaml.ws.message.decoder.BaseMessageDecoder

Throws:

org.opensaml.ws.message.decoder.MessageDecodingException

isMessageSigned

protected boolean isMessageSigned(SAMLMessageContext messageContext)

Determine whether the SAML message represented by the message context is digitally signed.

The default behavior is to examine whether an XML signature is present on the SAML protocol message. Subclasses may augment or replace with binding-specific behavior.

Overrides:

isMessageSigned in class BaseSAMLMessageDecoder

Parameters:

messageContext - current message context

Returns:

true if the message is considered to be digitially signed, false otherwise

decodeMessage

protected java.io.InputStream decodeMessage(java.lang.String message)
                                     throws org.opensaml.ws.message.decoder.MessageDecodingException

Base64 decodes the SAML message and then decompresses the message.

Parameters:

message - Base64 encoded, DEFALTE compressed, SAML message

Returns:

the SAML message

Throws:

org.opensaml.ws.message.decoder.MessageDecodingException - thrown if the message can not be decoded
