findAttribute

public com.sun.xacml.cond.EvaluationResult findAttribute(URI attributeType,
                                                URI attributeId,
                                                URI issuer,
                                                URI subjectCategory,
                                                com.sun.xacml.EvaluationCtx context,
                                                int designatorType)

Used to get an attribute. If one of those values isn't being asked for, or if the types are wrong, then an empty bag is returned.

Overrides:

findAttribute in class AttributeFinderModule

Parameters:

attributeType - the datatype of the attributes to find, which must be time, date, or dateTime for this module to resolve a value

attributeId - the identifier of the attributes to find, which must be one of the three ENVIRONMENT_* fields for this module to resolve a value

issuer - the issuer of the attributes, or null if unspecified

subjectCategory - the category of the attribute or null, which ignored since this only handles non-subjects

context - the representation of the request data

designatorType - the type of designator, which must be ENVIRONMENT_TARGET for this module to resolve a value

Returns:

the result of attribute retrieval, which will be a bag with a single attribute, an empty bag, or an error
