Method Detail

getMethodFor

protected ObjectMethod getMethodFor(Object object,
                                    String property,
                                    Object value,
                                    IEolContext context)

invoke

public void invoke(Object target,
                   String property,
                   Object value,
                   IEolContext context)
            throws EolRuntimeException

Description copied from interface: IPropertySetter

Sets a property on a given object to the specified value.

Specified by:

invoke in interface IPropertySetter

Parameters:

target - The model element to update.

property - The name of the property of the model element.

value - The new value of the property.

context - The execution context.

Throws:

EolRuntimeException - If anything goes wrong in updating the value.

coerce

public Object coerce(Object target,
                     String property,
                     Object value,
                     IEolContext context)
              throws EolIllegalPropertyException

Description copied from interface: IReflectivePropertySetter

Coerces the given value such that it is permitted for this property. For example, in EMF single values can be stored in many-valued features only when they are first stored in a collection.

Specified by:

coerce in interface IReflectivePropertySetter

Throws:

EolIllegalPropertyException - when getObject is not a valid model object or when getProperty is not a property that getObject knows about.

conforms

public boolean conforms(Object target,
                        String property,
                        Object value,
                        IEolContext context)
                 throws EolIllegalPropertyException

Description copied from interface: IReflectivePropertySetter

Indicates whether the specified value is permitted for this property. For example, the value "John Doe" would conform for a string-typed property with lowerbound <= 1 and upperbound >= 1. The precise semantics of conformance differ between types of model.

Specified by:

conforms in interface IReflectivePropertySetter

Throws:

EolIllegalPropertyException - when getObject is not a valid model object or when getProperty is not a property that getObject knows about.
