                                                         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
