de.uni_hildesheim.sse.vil.expressions.translation.DeferredResolvableOperationExpression

class DeferredResolvableOperationExpression
extends Expression

Defines a deferrable resolvable operation expression, i.e., a currently unresolved "function pointer". This is needed, as all functions and operations are only known at the end of the translation process, while the initialization expressions of global variables are (currently) resolved before.

                                      Expression init)

Creates a resolvable operation expression.

Parameters:

cause - the Ecore instance causing this expression

varType - the actual variable type

Method Detail

inferType

public TypeDescriptor<?> inferType()
                            throws VilException

Description copied from class: Expression

Infers the type of this expression including the type of the contained sub-expressions.

Specified by:

inferType in class Expression

Returns:

the type of this expression

Throws:

VilException - in case that inferring the type fails

accept

public java.lang.Object accept(IExpressionVisitor visitor)

Specified by:

accept in class Expression

Parameters:

visitor - the visitor

Returns:

the result of visiting this expression (may be null)

Throws:

VilException - in case that visiting fails (e.g., execution)

getCause

org.eclipse.emf.ecore.EObject getCause()
