Constructor Detail

StandardAttributeMatch

public StandardAttributeMatch(URI attrCategory,
                              Function function,
                              AttributeValue matchAttributeValue,
                              Evaluatable evaluatable)
                       throws IllegalArgumentException

Create a new StandardAttributeMatch instance.

Parameters:

attrCategory - the associated attribute category.

function - the MatchFunction to be used for matching.

matchAttributeValue - the AttributeValue to compare against.

evaluatable - the evaluatable AttributeDesignator to select applicable request Attributes.

Method Detail

getAttributeCategory

public URI getAttributeCategory()

Returns the attribute category of this TargetMatch.

Specified by:

getAttributeCategory in interface AttributeMatch

Returns:

the attribute category.

getMatchFunction

public Function getMatchFunction()

Returns the Function used to do the matching.

Specified by:

getMatchFunction in interface AttributeMatch

Returns:

the match function

getMatchValue

public AttributeValue getMatchValue()

Returns the AttributeValue used by the matching function.

Specified by:

getMatchValue in interface AttributeMatch

Returns:

the AttributeValue for the match

getMatchEvaluatable

public Evaluatable getMatchEvaluatable()

Returns the Evaluatable AttributeDesignator used by the matching function.

NOTE: Eventually, an "attribute selector" may also be associated with an AttributeMatch, thus the use of the Evaluatable interface rather than AttributeDesignator.

Specified by:

getMatchEvaluatable in interface AttributeMatch

Returns:

the attribute designator (and eventually a attribute selector) for the match

match

public MatchResult match(EvaluationContext evalContext)

Determines whether this AttributeMatch matches the input request (whether it is applicable)

Specified by:

match in interface AttributeMatch

Parameters:

evalContext - the representation of the request

Returns:

the result of trying to match the AttributeMatch and the request
