Method Detail

setSubjectAttributes

public void setSubjectAttributes(Map<String,String> attributeMap)

setResourceAttributes

public void setResourceAttributes(Map<String,String> attributeMap)

setActionAttributes

public void setActionAttributes(Map<String,String> attributeMap)

setEnvironmentAttributes

public void setEnvironmentAttributes(Map<String,String> attributeMap)

setAttributeMap

protected void setAttributeMap(String mapKey,
                               Map<String,String> attributeMap)

getAttributeMap

protected Map<String,Collection<AttributeBean>> getAttributeMap(org.jboss.security.xacml.sunxacml.EvaluationCtx eval)
                                                         throws URISyntaxException

This method extracts the attributes listed in the indexMap from the given evaluation context.

Parameters:

eval - the Evaluation Context from which to extract Attributes

Returns:

a Map of Attributes for each category (Subject, Resource, Action, Environment)

Throws:

URISyntaxException

handleDocument

protected org.jboss.security.xacml.sunxacml.AbstractPolicy handleDocument(Document doc,
                                                                          org.jboss.security.xacml.sunxacml.finder.PolicyFinder policyFinder)
                                                                   throws org.jboss.security.xacml.sunxacml.ParsingException

A private method that handles reading the policy and creates the correct kind of AbstractPolicy. Because this makes use of the policyFinder, it cannot be reused between finders. Consider moving to policyManager, which is not intended to be reused outside of a policyFinderModule, which is not intended to be reused amongst PolicyFinder instances.

Throws:

org.jboss.security.xacml.sunxacml.ParsingException

makeComponents

protected static String[] makeComponents(String resourceId)

Splits a XACML hierarchical resource-id value into a set of resource-id values that can be matched against a policy. Eg an incoming request for /res1/res2/res3/.* should match /res1/.* /res1/res2/.* /res1/res2/res3/.* in policies.

Parameters:

resourceId - XACML hierarchical resource-id value

Returns:

array of individual resource-id values that can be used to match against policies
