All Implemented Interfaces:

public class UiObjectInvocationHandler

extends SuppleUiObjectHierarchyElementImpl

implements java.lang.reflect.InvocationHandler, ConstraintManipulation

The invocation handler is used to copy UiObjects. It allows the creation of a new pseudo-UIObject, which has its own unique id and its own location within the object hierarchy. However, it's functionality and behavior is identical to the original UIObject. Moreover, changes in one UIObject are visible in the other.

Constructor Detail

UiObjectInvocationHandler

public UiObjectInvocationHandler(UiObject object,
                                 SuppleType type)

Creates a new invocation handler, that references another UIObject.

Parameters:

object -

Method Detail

invoke

public java.lang.Object invoke(java.lang.Object typeObject,
                               java.lang.reflect.Method method,
                               java.lang.Object[] args)
                        throws java.lang.Throwable

The invoke method of this handler is called when a method of the pseudo- UIObject is called. Inside invoke the call is forwarded to the actual method implementation, which could be user-defined (in this class) or which could be an existing implementation of the original UIObject.

Specified by:

invoke in interface java.lang.reflect.InvocationHandler

Throws:

java.lang.Throwable

See Also:

InvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])

getName

public java.lang.String getName()

Specified by:

getName in interface SuppleUiObjectHierarchyElement

Overrides:

getName in class SuppleUiObjectHierarchyElementImpl

Returns:

a unique name used to distinguish among different children of the parent type; if the name is not set and there is no parent, string "root" is returned

getUiObject

public UiObject getUiObject()

setUiObject

public void setUiObject(UiObject object)

setType

public void setType(SuppleType type)

getType

public SuppleType getType()

getParent

public ContainerType getParent()

Description copied from interface: SuppleUiObjectHierarchyElement

Returns the parent type of this type (i.e. the container type that contains this one)

Specified by:

getParent in interface SuppleUiObjectHierarchyElement

Overrides:

getParent in class SuppleUiObjectHierarchyElementImpl

setParent

public void setParent(ContainerType parent)

Description copied from interface: SuppleUiObjectHierarchyElement

Sets the parent type of this type instance -- you shouldn't need to call this method (it's already automatically called in all the right places)

Specified by:

setParent in interface SuppleUiObjectHierarchyElement

Overrides:

setParent in class SuppleUiObjectHierarchyElementImpl

isRoot

public boolean isRoot()

Description copied from interface: SuppleUiObjectHierarchyElement

Checks if this type objects is the root of the interface description

Specified by:

isRoot in interface SuppleUiObjectHierarchyElement

Overrides:

isRoot in class SuppleUiObjectHierarchyElementImpl

getParentObject

public UiObject getParentObject()

Specified by:

getParentObject in interface SuppleUiObjectHierarchyElement

Overrides:

getParentObject in class SuppleUiObjectHierarchyElementImpl

getTarget

public UiObject getTarget()

addRenderingHint

public void addRenderingHint(RenderingHint hint)

Specified by:

addRenderingHint in interface ConstraintManipulation

getRenderingHints

public java.util.Vector getRenderingHints()

Specified by:

getRenderingHints in interface ConstraintManipulation

addRenderingConstraint

public void addRenderingConstraint(RenderingConstraint constr)

Specified by:

addRenderingConstraint in interface ConstraintManipulation

getRenderingConstraints

public java.util.Vector getRenderingConstraints()

Specified by:

getRenderingConstraints in interface ConstraintManipulation

getUniqueId

public int getUniqueId()

Returns a unique id of this instantiation.

Returns:

unique id

equals

public boolean equals(java.lang.Object obj)

This method is absolutely necessary for proxy objects. Otherwise proxy objects cannot be used with
