Constructor Summary

Constructors

Constructor and Description
Attribute(URI id, String issuer, DateTimeAttribute issueInstant, AttributeValue value) Creates a new Attribute of the type specified in the given AttributeValue.
Attribute(URI id, URI type, String issuer, DateTimeAttribute issueInstant, AttributeValue value) Deprecated. As of version 1.1, replaced by Attribute(URI,String,DateTimeAttribute,AttributeValue). This constructor has some ambiguity in that it allows a specified datatype and a value that already has some associated datatype. The new constructor clarifies this issue by removing the datatype parameter and using the datatype specified by the given value.
