Class CompositeImpl

java.lang.Object

net.sf.jguiraffe.gui.builder.components.CompositeImpl

All Implemented Interfaces:

AccessibleComposite, Composite

public class CompositeImpl
extends Object
implements AccessibleComposite

A straight-forward implementation of the Composite interface.

This implementation uses member fields to store and expose the data required by the Composite interface. It can be used by other implementations as delegate. This implementation is not thread-safe.

Method Detail

addComponent

public void addComponent(Object comp,
                         Object constraints)

Adds the specified component to this container using the given constraints. This implementation adds the specified component and constraints object to an internal collection. This information can be queried using the getComponents() method.

Specified by:

addComponent in interface Composite

Parameters:

comp - the component to add

constraints - the constraints (may be null )

getLayout

public Object getLayout()

Returns the layout object passed to this instance. This implementation returns the object which has been set using the setLayout(Object) method.

Specified by:

getLayout in interface AccessibleComposite

Returns:

the layout object

setLayout

public void setLayout(Object layout)

Sets the layout object for this container. This implementation stores the passed in layout object in an internal field.

Specified by:

setLayout in interface Composite

Parameters:

layout - the layout object

getContainer

public Object getContainer()

Returns the concrete container component that is wrapped by this object. The returned container will be specific for the used GUI library. This implementation returns the container object set by the setContainer(Object) method.

Specified by:

getContainer in interface Composite

Returns:

the GUI library specific container

setContainer

public void setContainer(Object container)

Sets the container represented by this object. The object passed to this method is directly returned by getContainer().

Parameters:

container - the container

getComponents

public Collection<Object[]> getComponents()

Returns an unmodifiable collection with the components and constraints that have been added to this object. Each element of the collection is an array of size 0. Index 0 contains the component, index 1 contains the constraints object. This implementation returns a collection with the data set by all previous addComponent(Object, Object) calls.

Specified by:

getComponents in interface AccessibleComposite

Returns:

a collection with the components and constraints added to this object
