base64BinarySetEquals Function Description
Description
This method returns true if both sets of attribute values of type base64Binary are equal. Technically, it uses the subset function on the first and second arguments ANDed with the subset function and the second and first argument. Note that duplicate values have no impact on the comparison. For instance, the following 2 sets are equal: [a,a,c,b] and [b,c,a,c].
base64BinarySetEquals belongs to the ALFA function reference's
Set functions category. It maps to the XACML function identifier
urn:oasis:names:tc:xacml:1.0:function:base64Binary-set-equals, takes 2 arguments and returns a value of type boolean.
