public class TypeCheck3AsTypeCalculator
extends TypeCalculator

the TypeCalculator class using the TypeCheck3. While the TypeCheck3 should be used directly, this can be used to try the TypeCheck without major rewrites.

Method Detail

compatible

public boolean compatible(SymTypeExpression left,
                          SymTypeExpression right)

Description copied from interface: ITypeRelations

Function 3: Given two SymTypeExpressions super, sub: This function answers, whether the right type is a subtype of the left type in an assignment. (This allows to store/use values of type "sub" at all positions of type "super". Compatibility examples: compatible("int", "long") (in all directions) compatible("long", "int") (in all directions) compatible("double", "float") (in all directions) compatible("Person", "Student") (uni-directional)

Incompatible: !compatible("double", "int") (in all directions)

The concrete Typechecker has to decide on further issues, like !compatible("List<double>", "List<int>") where e.g. Java and OCL/P differ in their answers

Specified by:

compatible in interface ITypeRelations

Overrides:

compatible in class TypeCalculator

Parameters:

left - Super-Type

right - Sub-Type (assignment-compatible to supertype?)

isSubtypeOf

public boolean isSubtypeOf(SymTypeExpression subType,
                           SymTypeExpression superType)

Description copied from interface: ITypeRelations

determines if one SymTypeExpression is a subtype of another SymTypeExpression

Specified by:

isSubtypeOf in interface ITypeRelations

Overrides:

isSubtypeOf in class TypeCalculator

Parameters:

subType - the SymTypeExpression that could be a subtype of the other SymTypeExpression

superType - the SymTypeExpression that could be a supertype of the other SymTypeExpression
