Parameters:

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

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

inputStream - the InputStream of the Policy

Returns:

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

getPolicyReferene

public static PolicyReference getPolicyReferene(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)

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

getPolicyReference

public static PolicyReference getPolicyReference(Object element)
