Method Detail

getApplicablePolicySets

public java.util.List<PolicySet> getApplicablePolicySets()

Description copied from interface: PolicySetAttachPoint

Returns a list of policy sets defined in the domain, that are applicable to this PolicySetAttachPoint. An applicable PolicySet is one that include this PolicySetAttachPoint as part of its 'appliesTo' XPath attribute.

Specified by:

getApplicablePolicySets in interface PolicySetAttachPoint

Returns:

a list of policy sets applicable to this PolicySetAttachPoint

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from interface: Contract

Returns a clone of the contract.

Specified by:

clone in interface Contract

Overrides:

clone in class java.lang.Object

Returns:

a clone of the reference

Throws:

java.lang.CloneNotSupportedException

getBindings

public java.util.List<Binding> getBindings()

Description copied from interface: Contract

Returns the bindings supported by this contract.

Specified by:

getBindings in interface Contract

Returns:

the bindings supported by this contract

getBinding

public <B> B getBinding(java.lang.Class<B> bindingClass)

Description copied from interface: Contract

Returns a binding of the specified type or null if there is no such binding configured on this contract.

Specified by:

getBinding in interface Contract

Type Parameters:

B - the binding type

Parameters:

bindingClass - the binding type class

Returns:

the binding or null if there is no binding of the specified type

getCallbackBinding

public <B> B getCallbackBinding(java.lang.Class<B> bindingClass)

Description copied from interface: Contract

Returns a callback binding of the specified type or null if there is no such callback binding configured on this contract.

Specified by:

getCallbackBinding in interface Contract

bindingClass - the callback binding type class

Returns:

the callback binding or null if there is no callback binding of the specified type

isWiredByImpl

public boolean isWiredByImpl()

Description copied from interface: Reference

Returns a boolean value, "false" by default, which indicates that the implementation wires this reference dynamically.

Specified by:

isWiredByImpl in interface Reference

Returns:

true if the implementation wires this reference dynamically
