java.lang.Object
  org.apache.neethi.PolicyEngine

public class PolicyEngine
extends java.lang.Object

PolicyEngine provides set of methods to create a Policy object from an InputStream, OMElement, .. etc. It maintains an instance of AssertionBuilderFactory that can return AssertionBuilders that can create a Domain Assertion out of an OMElement. These AssertionBuilders are used when constructing a Policy object.

registerBuilder

public static void registerBuilder(javax.xml.namespace.QName qname,
                                   AssertionBuilder builder)

Registers an AssertionBuilder instances and associates it with a QName. PolicyManager or other AssertionBuilders instances can use this AssertionBuilder instance to process and build an Assertion from a OMElement with the specified QName.

Parameters:

qname - the QName of the Assertion that the Builder can build

builder - the AssertionBuilder that can build assertions that of 'qname' type

getPolicy

public static Policy getPolicy(java.io.InputStream inputStream)

Creates a Policy object from an InputStream.

Parameters:

inputStream - the InputStream of the Policy

Returns:

a Policy object of the Policy that is fed as a InputStream

getPolicyReferene

public static PolicyReference getPolicyReferene(java.io.InputStream inputStream)

Creates a PolicyReference object.

Parameters:

inputStream - the InputStream of the PolicyReference

Returns:

a PolicyReference object of the PolicyReference

getPolicy

public static Policy getPolicy(org.apache.axiom.om.OMElement element)

Creates a Policy object from an OMElement.

Parameters:

element - the Policy element

getPolicyReference

public static PolicyReference getPolicyReference(org.apache.axiom.om.OMElement element)

Creates a PolicyReference object from an OMElement.

Parameters:

element - the PolicyReference element

Returns:

a PolicyReference object of the PolicyReference element
