Interface OclReal

All Superinterfaces:

OclAny

All Known Subinterfaces:

OclInteger

All Known Implementing Classes:

IntegerInstance, RealInstance

public interface OclReal

extends OclAny

Represents and identifies the OCL 1.5 type Real. It is used by the context checker to reflect operations of and to identify the type within the OCL-context. The names of the operations had to be adapted to java conform method names (therefore they must be remapped to the ocl names to be compareable). Each instance of this interface is handled as an OCL instance of the type Real during the evaluation process. Its methods are used to describe the predefined properties of the type. For a complete description of the type and its properties (to be specific for this class and its methods) refer to the type description of OCL 1.5.
