Class JellyContextBeanStore

java.lang.Object
  net.sf.jguiraffe.gui.builder.impl.JellyContextBeanStore

All Implemented Interfaces:

BeanStore

public class JellyContextBeanStore
extends java.lang.Object
implements BeanStore

A specialized implementation of the BeanStore interface that is backed by a Jelly context.

This class provides access to the variables stored in a Jelly context through the methods defined by the BeanStore interface. This way a Jelly context (e.g. initialized by a builder operation) can transparently be used by the dependency injection framework.

Constructor Detail

JellyContextBeanStore

public JellyContextBeanStore(org.apache.commons.jelly.JellyContext ctx,
                             BeanStore parentStore,
                             java.lang.String storeName)

Creates a new instance of JellyContextBeanStore and initializes it with the underlying Jelly context, the parent bean store and the name to be used.

Parameters:

ctx - the Jelly context (must not be null)

parentStore - the parent store

storeName - the name

Throws:

java.lang.IllegalArgumentException - if the passed in Jelly context is null

JellyContextBeanStore

public JellyContextBeanStore(org.apache.commons.jelly.JellyContext ctx,
                             BeanStore parentStore)

Creates a new instance of JellyContextBeanStore and initializes it with the underlying Jelly context and the parent bean store. For the name a default value is used.

Parameters:

ctx - the Jelly context (must not be null)

parentStore - the parent store

Method Detail

getContext

public org.apache.commons.jelly.JellyContext getContext()

Returns the underlying Jelly context.

Returns:

the Jelly context

getBeanProvider

public BeanProvider getBeanProvider(java.lang.String name)

Returns a BeanProvider for accessing the bean with the given name. This implementation checks whether the Jelly context contains a variable with the given name. If this is the case, a bean provider serving this value is returned. Otherwise the result of this method is null.

Specified by:

getBeanProvider in interface BeanStore

Parameters:

name - the name of the desired bean

Returns:

a BeanProvider for this bean

getName

public java.lang.String getName()

Returns the name of this bean store.

Specified by:

getName in interface BeanStore

Returns:

the name of this bean store

getParent

public BeanStore getParent()

Returns the parent bean store.

Specified by:

getParent in interface BeanStore

Returns:

the parent bean store

providerNames

public java.util.Set<java.lang.String> providerNames()

Returns a set with the names of the existing BeanProviders. This implementation returns a set with the names of the variables defined in the underlying Jelly context.

Specified by:

providerNames in interface BeanStore

Returns:

a set with the names of the known bean providers
