Method Detail

getEqualityOperatorImplementation

public final OperatorImplementation_V0104 getEqualityOperatorImplementation()

Description copied from class: AbstractTypeImplementation_V0105

Gets the implementation object for the equality operator pertaining to this type.

Specified by:

getEqualityOperatorImplementation in class AbstractTypeImplementation_V0105

Returns:

the implementation object for the equality operator pertaining to this type.

getOrderingOperatorImplementation

public final OperatorImplementation_V0104 getOrderingOperatorImplementation()
                                                                     throws TypeIsNotOrderedException

Description copied from class: AbstractTypeImplementation_V0105

Gets the implementation object for the ordering operator (GT) pertaining to this type.

Specified by:

getOrderingOperatorImplementation in class AbstractTypeImplementation_V0105

Returns:

the implementation object for the ordering operator pertaining to this type. Null if there is no such operator.

Throws:

TypeIsNotOrderedException - If the type is not ordered

getPossrepImplementation

public final PossRepImplementation getPossrepImplementation(java.lang.String componentName)
                                                     throws NotFoundException

Description copied from class: AbstractTypeImplementation_V0105

Gets the PossrepImplementation object implementing the possrep of which the given component name names a component. This method is introduced in version 1.3. The method is optional, but implementers are strongly encouraged to add this method to any implementing class they already have developed.

Specified by:

getPossrepImplementation in class AbstractTypeImplementation_V0105

Parameters:

componentName - The name of a component of some possrep of this type (and for which the corresponding PossrepImplementation object is to be returned)

Returns:

The PossrepImplementation object implementing the possrep of which the given component name names a component

Throws:

NotFoundException - If the type does not have any possrep with a component of the given name

getRootTypeName

public final java.lang.String getRootTypeName()

Description copied from class: AbstractTypeImplementation_V0105

Gets the name of the 'root' type that this type ultimately derives from (through specialization by constraint).

Specified by:

getRootTypeName in class AbstractTypeImplementation_V0105

Returns:

the name of the 'root' type that this type ultimately derives from (through specialization by constraint).

isOfType

public final boolean isOfType(AbstractTypeImplementation_V0105 type)

Description copied from class: AbstractTypeImplementation_V0105

Checks whether this type is either the given type itself, or is a constrainedtype whose [ultimate] base type is the given type

Specified by:

isOfType in class AbstractTypeImplementation_V0105

Parameters:

type - The type for which it is to be tested whether this type is a "subtype" of it

Returns:

True if this type is the same as the given type, or if this type is a constrained type whose base type is the named type
