Constructor Detail

MacroAssign

public MacroAssign()

MacroAssign

public MacroAssign(IFunctor<T> functor,
           String assignTo)

Method Detail

configure

public void configure(IElement element)
               throws ConfigurationException

Specified by:

configure in interface IElementConfigurable

Overrides:

configure in class MacroFunctor<T>

Throws:

ConfigurationException

dispose

public void dispose()
             throws FunctorInvocationException

Throws:

FunctorInvocationException

getAssignTo

public String getAssignTo()

getLabel

public String getLabel()

Description copied from interface: IPresentationSupport

A short string representation (suitable for example for use with an icon or menu item).

Specified by:

getLabel in interface IPresentationSupport

Overrides:

getLabel in class MacroFunctor<T>

Returns:

A short string representation (suitable for example for use with an icon or menu item).

getValueExpression

public IFunctor getValueExpression()

perform

public T perform(IFunctorCall call)
          throws FunctorInvocationException

Description copied from interface: IFunctor

Perform the encapsulated business logic in the context defined in "call".

Parameters:

call - The call context

Returns:

The behavior execution result.

Throws:

FunctorInvocationException - An exception that raised while executing the business logic will be wrapped in a FunctorInvocationException.

serialize

public void serialize(IElement element)
               throws ElementSerializationException

Description copied from interface: IElementSerializable

Serialize the state in element. element represents the receiver immediately, it contains the state information directly, not as a child element. This means most of the time you have to change the element name itself and add child elements.

Specified by:

serialize in interface IElementSerializable

Overrides:

serialize in class MacroFunctor<T>

Throws:

ElementSerializationException

setAssignTo

public void setAssignTo(String assignTo)

setValueExpression

public void setValueExpression(IFunctor functor)
