      com.sun.xacml.cond.EqualFunction

All Implemented Interfaces:

Function

public class EqualFunction

extends FunctionBase

A class that implements all the *-equal functions. It takes two operands of the appropriate type and returns a BooleanAttribute indicating whether both of the operands are equal. If either of the operands is indeterminate, an indeterminate result is returned.

Since:

1.0

Constructor Detail

EqualFunction

public EqualFunction(java.lang.String functionName)

Creates a new EqualFunction object that supports one of the standard type-equal functions. If you need to create an instance for a custom type, use the getEqualInstance method or the alternate constructor.

---

EqualFunction

public EqualFunction(java.lang.String functionName,
                     java.lang.String argumentType)

Creates a new EqualFunction object.

Method Detail

getEqualInstance

public static EqualFunction getEqualInstance(java.lang.String functionName,
                                             java.lang.String argumentType)

Returns an EqualFunction that provides the type-equal functionality over the given attribute type. This should be used to create new function instances for any new attribute types, and the resulting object should be put into the FunctionFactory (instances for the standard types are pre-installed in the standard factory).

Note that this method has the same affect as invoking the constructor with the same parameters. This method is provided as a convenience, and for symmetry with the bag and set functions.

---

getArgumentType

private static java.lang.String getArgumentType(java.lang.String functionName)

Private helper that returns the type used for the given standard type-equal function.

---

getSupportedIdentifiers

public static java.util.Set getSupportedIdentifiers()

Returns a Set containing all the function identifiers supported by this class.

---

evaluate

public EvaluationResult evaluate(java.util.List inputs,
                                 com.sun.xacml.EvaluationCtx context)

Evaluate the function, using the specified parameters.
