setEnvironmentAttributes

public void setEnvironmentAttributes(Set<String> attributes)

setResourceAttributes

public void setResourceAttributes(Set<String> attributes)

setSubjectAttributes

public void setSubjectAttributes(Set<String> attributes)

init

public void init()
          throws AttributeFinderException

Throws:

AttributeFinderException

isDesignatorSupported

public boolean isDesignatorSupported()

Returns true always because this module supports designators.

Overrides:

isDesignatorSupported in class AttributeFinderModule

Returns:

true always

getSupportedDesignatorTypes

public Set<Integer> getSupportedDesignatorTypes()

Overrides:

getSupportedDesignatorTypes in class AttributeFinderModule

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

canHandleAdhoc

protected boolean canHandleAdhoc()

Specified by:

canHandleAdhoc in class AttributeFinderModule

getAttributeLocally

protected Object getAttributeLocally(int designatorType,
                                     String attributeId,
                                     URI resourceCategory,
                                     com.sun.xacml.EvaluationCtx context)

Will not be called in this implementation, since findAttribute is overridden

Specified by:
