Method Detail

getDispatchedBean

java.lang.Object getDispatchedBean(java.lang.Class dispachtedBeanClass)

Find managed bean for class. If the bean already exists then the bean is returned. If it does not exist yet then a new instance will be created.

removeDispatchedBean

void removeDispatchedBean(java.lang.Class dispatchedBeanClass)

Removes dispatched bean from dispatcher.

getDispatchedBean

java.lang.Object getDispatchedBean(java.lang.String dispatchedBeanName)

Find managed bean for name. If the bean already exists then the beans is returned. If it does not exist yet then a new instance will be created.

Parameters:

dispatchedBeanName - Name of the beans - this is the name that is used for binding the bean within the user interface, as well. E.g. if the bean's binding is "#{d.AbcdeUI. ...} then you may access the bean by passing "AbcdeUI".

removeDispatchedBean

void removeDispatchedBean(java.lang.String dispatchedBeanName)

Removes dispatched bean from dispatcher.

getExpressionBase

java.lang.String getExpressionBase()

Each dispatcher is the entry point to its managed beans. Dispatchers themselves may be nested. This method returns the expression of this dispatcher instance.

createSubDispatcherInstance

IDispatcher createSubDispatcherInstance()

A dispatcher may have other dispatchers below. This method creates a sub dispatcher.

destroy

void destroy()

Destroys the dispatcher and its contained objects.

updateExpression

java.lang.String updateExpression(java.lang.String expression)

Within the bean processing you may create components in a dynamic way, e.g. using the feature "componentbinding". When assigning expression to component you need to pay attention that the binding fits to the dispatcher environment in which your bean resides.
This method builds an expression that is relative to the current dispatcher.

Parameters:

expression - The normal expression, e.g. "#{d.Car}".

Returns:

The relative expression, e.g. "#{d.d_1.Car}".

getContentReplace

java.lang.String getContentReplace()

Returns the content replace statement that is passed to included pages. Returns a value like "#{d.:#{d.d_1.".

getMyExpression

java.lang.String getMyExpression(java.lang.Object o)

Returns the expression for the object that is managed inside the dispatcher.

Returns:

Expression of object: "#{d.xyz}"

getMyExpression

java.lang.String getMyExpression(java.lang.Class cl)

Returns the expression for the object that is managed inside the dispatcher.

Returns:

Expression of object: "#{d.xyz}"

getOwner

IDispatcher getOwner()

Passes back the dispatcher above. Null is returned if the current instance is the top dispatcher

getTopOwner

IDispatcher getTopOwner()

Passes back the top owner of the dispatcher hierarchy. If the current dispatcher is the top owner itself, then the current dispatcher is returned.

createModalPopup

ModalPopup createModalPopup()

Create a modal popup instance within the workpage context.

createModelessPopup

ModelessPopup createModelessPopup()

Create a modeless popup instance within the workpage context.

setOwner

void setOwner(IDispatcher owner)

unregisterSubDispatcherInstance

void unregisterSubDispatcherInstance(IDispatcher subDispatcher)

createSubDispatcherIndex

int createSubDispatcherIndex()

getChildDispatchers

java.util.List<IDispatcher> getChildDispatchers()

Returns a list of child dispatchers - if the dispatcher is hierarchized.

checkIfDispatchedBeanIsLoaded

boolean checkIfDispatchedBeanIsLoaded(java.lang.Class dispatchedBeanClass)

checkIfDispatchedBeanIsLoaded

boolean checkIfDispatchedBeanIsLoaded(java.lang.String dispatchedBeanName)
