Class PolicyBuilder

java.lang.Object

org.apache.neethi.PolicyBuilder

public class PolicyBuilder
extends java.lang.Object

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

Method Detail

registerBuilder

public 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 element 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

getPolicyRegistry

public PolicyRegistry getPolicyRegistry()

The PolicyEngine can have a default PolicyRegistry that the Policy objects that it creates are setup to use when normalize is called without the PolicyRegistry.

Returns:

the default PolicyRegistry

setPolicyRegistry

public void setPolicyRegistry(PolicyRegistry reg)

getAssertionBuilderFactory

public AssertionBuilderFactory getAssertionBuilderFactory()

getPolicy

public 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

getPolicy

public Policy getPolicy(org.w3c.dom.Element el)

getPolicy

public Policy getPolicy(javax.xml.stream.XMLStreamReader reader)

getPolicy

public Policy getPolicy(java.lang.Object element)

Creates a Policy object from an element.

Parameters:

element - the Policy element

Returns:

a Policy object of the Policy element

getPolicyReference

public PolicyReference getPolicyReference(java.io.InputStream inputStream)

Creates a PolicyReference object.

Parameters:

inputStream - the InputStream of the PolicyReference

Returns:

a PolicyReference object of the PolicyReference

getPolicyReference

public PolicyReference getPolicyReference(java.lang.Object element)

Creates a PolicyReference object from an element.

Parameters:

element - the PolicyReference element

Returns:

a PolicyReference object of the PolicyReference element

getPolicyOperator

private Policy getPolicyOperator(java.lang.Object element)

getExactlyOneOperator

private ExactlyOne getExactlyOneOperator(java.lang.Object element)

getAllOperator

private All getAllOperator(java.lang.Object element)

processOperationElement

private PolicyOperator processOperationElement(java.lang.Object operationElement,
                                               PolicyOperator operator)

notifyUnknownPolicyElement

protected void notifyUnknownPolicyElement(java.lang.Object childElement)
