Constructor Detail

AbstractComplexEMFBinding

public AbstractComplexEMFBinding()
Default constructor.

Creatign the binding with this constructor will force it to perform a noop in the parse(ElementInstance, Node, Object) method.


AbstractComplexEMFBinding

public AbstractComplexEMFBinding(EFactory factory)
Constructs the binding with an efactory.

Parameters:
factory - Factory used to create model objects.

AbstractComplexEMFBinding

public AbstractComplexEMFBinding(EFactory factory,
                                 Class type)
Constructs the binding with an efactory and a type.

Parameters:
factory - Factory used to create model objects.
Method Detail

getType

public Class getType()
Dynamically tries to determine the type of the object using emf naming conventions and the name returned by Binding.getTarget().

This implementation is a heuristic and is not guaranteed to work. Subclasses may override to provide the type explicitly.

Returns:
The java type this binding maps to.

parse

public Object parse(ElementInstance instance,
                    Node node,
                    Object value)
             throws Exception
Uses EMF reflection to create an instance of the EMF model object this binding maps to.

The properties of the resulting object are set using the the contents of node. In the case that the name of a child element or attributes does not match the name of a property on the object, subclasses may wish to extend this method and set the property explicitly.

Specified by:
parse in interface ComplexBinding
Overrides:
parse in class AbstractComplexBinding
Parameters:
instance - The element being parsed.
node - The node in the parse tree representing the element being parsed.
value - The result of the parse from another strategy in the type hierarchy. Could be null if this is the first strategy being executed.
Returns:
The parsed object, or null if the component could not be parsed.
Throws:
Exception - Strategy objects should not attempt to handle any exceptions.

createEObject

protected EObject createEObject(Object value)
                         throws Exception
Reflectively creates an instance of the target object.

Throws:
Exception

setProperty

protected void setProperty(EObject eObject,
                           String property,
                           Object value,
                           boolean lax)
Internal method for reflectively setting the property of an eobject.

Subclasses may override.


getProperty

public Object getProperty(Object object,
                          QName name)
                   throws Exception
Uses EMF reflection dynamically return the property with the specified name.

In the case that the name of a child element or attributes does not match the name of a property on the object, subclasses may wish to extend this method and set the property explicitly.

Specified by:
getProperty in interface ComplexBinding
Overrides:
getProperty in class AbstractComplexBinding
Parameters:
object - The object being encoded.
name - The name of the property to obtain.
Returns:
The value of the property, or null.
Throws:
Exception

ComplexBinding.getProperty(Object, QName)
