Method Detail

checkPropertyIds

public Set<String> checkPropertyIds(Set<String> propertyIds)

Allow delegates to support special properties not stack defined.

Specified by:

checkPropertyIds in interface PropertyProvider

Overrides:

checkPropertyIds in class BaseProvider

Returns:

a subset of the given property id set containing any property ids not supported by this resource provider. An empty return set indicates that all of the given property ids are supported.

populateResources

public Set<Resource> populateResources(Set<Resource> resources,
                                       Request request,
                                       Predicate predicate)
                                throws SystemException

Description copied from interface: PropertyProvider

Populate the given set of resource with any properties that this property provider can provide and return a populated set of resources. The provider may drop resources from the original set if it determines that the don't meet the conditions of the predicate.

Parameters:

resources - the resources to be populated

request - the request object which defines the desired set of properties

predicate - the predicate object which filters which resources are returned

Returns:

the populated set of resources

Throws:

SystemException - thrown if resources cannot be populated
