Method Detail

getMethodFor

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

invoke

public void invoke(Object value)
            throws EolRuntimeException

Specified by:

invoke in interface IPropertySetter

Throws:

EolRuntimeException

coerce

public Object coerce(Object value)
              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 value)
                 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.
