  org.opensaml.ws.security.provider.BaseTrustEngineRule<TokenType>

Type Parameters:

TokenType - type of token which is being evaluated by the underlying trust engine

All Implemented Interfaces:

SecurityPolicyRule

Direct Known Subclasses:

ClientCertAuthRule

public abstract class BaseTrustEngineRule<TokenType>
extends Object
implements SecurityPolicyRule

Base rule which uses a trust engine to evaluate a token extracted from the request or message.

Constructor Summary

BaseTrustEngineRule(org.opensaml.xml.security.trust.TrustEngine<TokenType> engine)
Constructor.

Method Summary

protected abstract org.opensaml.xml.security.CriteriaSet	buildCriteriaSet(String entityID, MessageContext messageContext) Subclasses are required to implement this method to build a criteria set for the trust engine according to trust engine and application-specific needs.
protected boolean	evaluate(TokenType token, org.opensaml.xml.security.CriteriaSet criteriaSet) Evaluate the token against the specified criteria using the configured trust engine.
protected boolean	evaluate(TokenType token, String entityID, MessageContext messageContext) Evaluate the token using the configured trust engine against criteria built using the specified candidate issuer entity ID and message context information.
protected org.opensaml.xml.security.trust.TrustEngine<TokenType>	getTrustEngine() Gets the engine used to validate the untrusted token.

Constructor Detail

BaseTrustEngineRule

public BaseTrustEngineRule(org.opensaml.xml.security.trust.TrustEngine<TokenType> engine)

Constructor.

Parameters:

engine - Trust engine used to verify the particular token type

Method Detail

getTrustEngine

protected org.opensaml.xml.security.trust.TrustEngine<TokenType> getTrustEngine()

Gets the engine used to validate the untrusted token.

Returns:

engine engine used to validate the untrusted token

buildCriteriaSet

protected abstract org.opensaml.xml.security.CriteriaSet buildCriteriaSet(String entityID,
                                                                          MessageContext messageContext)
                                                                   throws SecurityPolicyException

Subclasses are required to implement this method to build a criteria set for the trust engine according to trust engine and application-specific needs.

Parameters:

entityID - the candidate issuer entity ID which is being evaluated

messageContext - the message context which is being evaluated

Returns:

a newly constructly set of criteria suitable for the configured trust engine

Throws:

SecurityPolicyException - thrown if criteria set can not be constructed

evaluate

protected boolean evaluate(TokenType token,
                           String entityID,
                           MessageContext messageContext)
                    throws SecurityPolicyException

Evaluate the token using the configured trust engine against criteria built using the specified candidate issuer entity ID and message context information.

Parameters:

token - the token to be evaluated

entityID - the candidate issuer entity ID which is being evaluated

messageContext - the message context which is being evaluated

Returns:

true if the token satisfies the criteria as determined by the trust engine, otherwise false

Throws:

SecurityPolicyException - thrown if there is a fatal error during trust engine evaluation

evaluate

protected boolean evaluate(TokenType token,
                           org.opensaml.xml.security.CriteriaSet criteriaSet)
                    throws SecurityPolicyException

Evaluate the token against the specified criteria using the configured trust engine.

Parameters:

token - the token to be evaluated

criteriaSet - the set of criteria against which to evaluate the token

Returns:

true if the token satisfies the criteria as determined by the trust engine, otherwise false

Throws:

SecurityPolicyException - thrown if there is a fatal error during trust engine evaluation
