Interface Expression

All Superinterfaces:
Element, org.eclipse.emf.ecore.EModelElement, org.eclipse.emf.ecore.EObject, NamedElement, org.eclipse.emf.common.notify.Notifier, PackageableElement, ParameterableElement, TypedElement, ValueSpecification
All Known Subinterfaces:
StringExpression
public interface Expression
extends ValueSpecification

A representation of the model object 'Expression'. An expression is a structured tree of symbols that denotes a (possibly empty) set of values when evaluated in a context. An expression represents a node in an expression tree, which may be non-terminal or terminal. It defines a symbol, and has a possibly empty sequence of operands which are value specifications.

The following features are supported:

                              boolean createOnDemand)
Retrieves the first ValueSpecification with the specified 'Name', and 'Type' from the 'Operand' containment reference list.

Parameters:
name - The 'Name' of the ValueSpecification to retrieve, or null.
type - The 'Type' of the ValueSpecification to retrieve, or null.
ignoreCase - Whether to ignore case in String comparisons.
eClass - The Ecore class of the ValueSpecification to retrieve, or null.
