public abstract class AbstractUnaryOperation
extends AbstractOperation
implements LibraryUnaryOperation

AbstractUnaryOperation defines the default implementation of a unary operation redirecting the call-expression invocation to the return type-id form.

Method Detail

dispatch

@Nullable
public java.lang.Object dispatch(@NonNull
                                          DomainEvaluator evaluator,
                                          @NonNull
                                          DomainCallExp callExp,
                                          @Nullable
                                          java.lang.Object sourceValue)

Description copied from interface: LibraryOperation

Return the result of evaluating callExp and its arguments upon sourceValue within the environment provided by evaluator. An invalid return may be indicated by throwing an exception, returning Java null, or returning OCL invalid.

This invocation evaluates the arguments as required. Derived implementations may implement short circuit processing to skip redundant evlaution of later arguments.

Invocations may bypass dispatch if a derived LibraryOperation such as LibrarySimpleBinaryOperation makes its internal evaluate signature available for use after a type test and cast.

Specified by:

dispatch in interface LibraryOperation

evaluate

@Nullable
public abstract java.lang.Object evaluate(@NonNull
                                                   DomainEvaluator evaluator,
                                                   @NonNull
                                                   TypeId returnTypeId,
                                                   @Nullable
                                                   java.lang.Object sourceValue)

Description copied from interface: LibraryUnaryOperation

Return the result of evaluating the operation on an argument. An invalid return may be indicated by throwing an exception returning Java null or OCL invalid.

Specified by:
