Examples of com.sun.xacml.finder.AttributeFinder

com.sun.xacml.finder.AttributeFinder
This class is used by the PDP to find attribute values that weren't originally supplied in the request. It can be called with the data supplied in {@link AttributeDesignator}s or {@link AttributeSelector}s. Because the modules in this finder may themselves need attribute data to search for attribute data, it's possible that the modules will look for values in the {@link EvaluationCtx}, which may in turn result in the invocation of this finder again, so module writers need to be careful about how they build their modules.
Note that unlike the PolicyFinder, this class doesn't always need to use every module it has to find a value. The ordering is maintained, however, so it will always start with the first module, and proceed in order until it finds a value or runs out of modules. @since 1.0 @author Seth ProctorAdding generic type support by Christian Mueller (geotools)
