All Implemented Interfaces:

net.shibboleth.utilities.java.support.component.Component, net.shibboleth.utilities.java.support.component.DestructableComponent, net.shibboleth.utilities.java.support.component.InitializableComponent, net.shibboleth.utilities.java.support.component.UnmodifiableComponent, org.opensaml.messaging.encoder.MessageEncoder<org.opensaml.saml.common.SAMLObject>

public class Pac4jHTTPRedirectDeflateEncoder
extends org.opensaml.messaging.encoder.AbstractMessageEncoder<org.opensaml.saml.common.SAMLObject>

Pac4j implementation extending directly the AbstractMessageEncoder as intermediate classes use the J2E HTTP response. It's mostly a copy/paste of the source code of these intermediate opensaml classes.

org.opensaml.messaging.encoder.MessageEncodingException

doInitialize

protected void doInitialize()
                     throws net.shibboleth.utilities.java.support.component.ComponentInitializationException

Overrides:

doInitialize in class org.opensaml.messaging.encoder.AbstractMessageEncoder<org.opensaml.saml.common.SAMLObject>

Throws:

net.shibboleth.utilities.java.support.component.ComponentInitializationException

getEndpointURL

protected java.net.URI getEndpointURL(org.opensaml.messaging.context.MessageContext<org.opensaml.saml.common.SAMLObject> messageContext)
                               throws org.opensaml.messaging.encoder.MessageEncodingException

Gets the response URL from the message context.

Parameters:

messageContext - current message context

Returns:

response URL from the message context

Throws:

org.opensaml.messaging.encoder.MessageEncodingException - throw if no relying party endpoint is available

removeSignature

protected void removeSignature(org.opensaml.saml.common.SAMLObject message)

Removes the signature from the protocol message.

Parameters:

message - current message context

marshallMessage

protected org.w3c.dom.Element marshallMessage(org.opensaml.core.xml.XMLObject message)
                                       throws org.opensaml.messaging.encoder.MessageEncodingException

Helper method that marshalls the given message.

Parameters:

message - message the marshall and serialize

Returns:

marshalled message

Throws:

org.opensaml.messaging.encoder.MessageEncodingException - thrown if the give message can not be marshalled into its DOM representation

buildRedirectURL

protected java.lang.String buildRedirectURL(org.opensaml.messaging.context.MessageContext<org.opensaml.saml.common.SAMLObject> messageContext,
                                            java.lang.String endpoint,
