de.intarsys.tools.macro.MacroCondition

All Implemented Interfaces:

IContextSupport, IFunctor, IElementConfigurable, IElementSerializable, IPresentationSupport, IClassLoaderSupport

public class MacroCondition
extends MacroFunctor

Implementation of conditional execution of an IFunctor. When the "if" expression does not exist or returns true, the "then" expression is executed, the "else" expression otherwise. The result is the result of the last IFunctor executed (this is either the "true" or the "false" expression).

Method Detail

configure

public void configure(IElement element)
               throws ConfigurationException

Specified by:

configure in interface IElementConfigurable

Overrides:

configure in class MacroFunctor

Throws:

ConfigurationException

getElseExpression

public IFunctor getElseExpression()

getIfExpression

public IFunctor getIfExpression()

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

Returns:

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

getThenExpression

public IFunctor getThenExpression()

perform

public Object 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

Throws:

ElementSerializationException

setContext

public void setContext(Object context)
                throws ConfigurationException

Specified by:

setContext in interface IContextSupport

Overrides:

setContext in class MacroFunctor

Throws:

ConfigurationException

setElseExpression

public void setElseExpression(IFunctor step)

setIfExpression

public void setIfExpression(IFunctor step)

setThenExpression

public void setThenExpression(IFunctor step)
