public final class PolicyModelGenerator extends Object
author

Fields Summary
private static final com.sun.xml.ws.policy.privateutil.PolicyLogger
LOGGER
private static final PolicyModelGenerator
generator
Constructors Summary
private PolicyModelGenerator()
This private constructor avoids direct instantiation from outside of the class

    
                    
      
        // nothing to initialize
Methods Summary
public static com.sun.xml.ws.policy.sourcemodel.PolicyModelGeneratorgetGenerator()
Factory method that returns {@link PolicyModelGenerator} instance.

return
{@link PolicyModelGenerator} instance

        return generator;
public PolicySourceModeltranslate(com.sun.xml.ws.policy.Policy policy)
This method translates a {@link Policy} into a {@link com.sun.xml.ws.policy.sourcemodel policy infoset}. The resulting PolicySourceModel is disconnected from the input policy, thus any additional changes in the policy will have no effect on the PolicySourceModel.

param
policy The policy to be translated into an infoset. May be null.
return
translated The policy infoset. May be null if the input policy was null.
throws
PolicyException in case Policy translation fails.

private ModelNodetranslate(ModelNode parentAssertion, com.sun.xml.ws.policy.NestedPolicy policy)
Iterates through a nested policy and return the corresponding policy info model.
