com.sun.xacml.attr
Class BaseAttributeFactory  

java.lang.Object
  com.sun.xacml.attr.AttributeFactory
      com.sun.xacml.attr.BaseAttributeFactory

Direct Known Subclasses:

StandardAttributeFactory

---

public class BaseAttributeFactory

extends AttributeFactory

This is a basic implementation of AttributeFactory. It implements the insertion and retrieval methods, but doesn't actually setup the factory with any datatypes.

Note that while this class is thread-safe on all creation methods, it is not safe to add support for a new datatype while creating an instance of a value. This follows from the assumption that most people will initialize these factories up-front, and then start processing without ever modifying the factories. If you need these mutual operations to be thread-safe, then you should write a wrapper class that implements the right synchronization.

Since:

1.2

BaseAttributeFactory

public BaseAttributeFactory(java.util.Map attributes)

Constructor that configures this factory with an initial set of supported datatypes.

Method Detail

addDatatype

public void addDatatype(java.lang.String id,
                        AttributeProxy proxy)

Adds a proxy to the factory, which in turn will allow new attribute types to be created using the factory. Typically the proxy is provided as an anonymous class that simply calls the getInstance methods (or something similar) of some AttributeValue class.

getSupportedDatatypes

public java.util.Set getSupportedDatatypes()

Returns the datatype identifiers supported by this factory.

createValue

public AttributeValue createValue(org.w3c.dom.Node root)
                           throws com.sun.xacml.UnknownIdentifierException,
                                  com.sun.xacml.ParsingException

Creates a value based on the given DOM root node. The type of the attribute is assumed to be present in the node as an XACML attribute named DataType, as is the case with the AttributeValueType in the policy schema. The value is assumed to be the first child of this node.

createValue

public AttributeValue createValue(org.w3c.dom.Node root,
                                  java.net.URI dataType)
                           throws com.sun.xacml.UnknownIdentifierException,
                                  com.sun.xacml.ParsingException

Creates a value based on the given DOM root node and data type.

public AttributeValue createValue(org.w3c.dom.Node root,
                                  java.lang.String type)
                           throws com.sun.xacml.UnknownIdentifierException,
                                  com.sun.xacml.ParsingException

Creates a value based on the given DOM root node and data type.

createValue

public AttributeValue createValue(java.net.URI dataType,
                                  java.lang.String value)
                           throws com.sun.xacml.UnknownIdentifierException,
                                  com.sun.xacml.ParsingException

Creates a value based on the given data type and text-encoded value. Used primarily by code that does an XPath query to get an attribute value, and then needs to turn the resulting value into an Attribute class.
