public class Reference
extends CustomDatatype

A reference allows the definition of individual configurations of an (external) element for the referencing element. Currently, operations such as assignments are represented as the respective operations of the base type. Actually, this may be confusing / wrong. See ConstraintSyntaxTree.inferDatatype().

type

private IDatatype type

Constructor Details

Reference

private Reference()

Creates the singleton instance for TYPE.

Reference

public Reference(String name,
 IDatatype type,
 ModelElement parent)

Constructor for the reference.

Parameters:

name - Name of reference

type - the type to refer to

parent - the object, in which this specific one is embedded

Method Details

getType

public IDatatype getType()

Returns the type this reference is referring to.

Specified by:

getType in interface IDatatype

Overrides:

getType in class CustomDatatype

Returns:

the type

accept

public void accept(IModelVisitor visitor)

Accept method for the visitor.

Parameters:

visitor - The visitor, which should process this model element.

accept

public void accept(IDatatypeVisitor visitor)

Description copied from interface: IDatatypeVisitable

Accepts a specialized visitor for creating a textual representation of the identity of this type.

Specified by:

accept in interface IDatatypeVisitable

Overrides:

accept in class ContainableModelElement

Parameters:

visitor - the visitor to accept

isAssignableFrom

public boolean isAssignableFrom(IDatatype type)

Determines if the data type represented by this object is either the same as, or is a supertype of type.

Specified by:

isAssignableFrom in interface IDatatype

Overrides:

isAssignableFrom in class CustomDatatype

Parameters:

type - the type being checked

Returns:

true if this type is either the same or a supertype of type, true else

dereference

public static IDatatype dereference(IDatatype type)

Aims at dereference type in case that it is a reference.

Parameters:

type - the type to dereference

Returns:

the dereferenced type (or type if type was not a reference)

dereference

public static void dereference(IDatatype[] types)

Dereferences all datatypes in type.

Parameters:

types - the types to be dereferenced

isReferenceTo

public static boolean isReferenceTo(IDatatype type,
 IDatatype parameter)

Returns whether the given type is a reference with given generic.

Parameters:

type - the type to check

parameter - the parameter type of the expected reference (may also be a more generic type)

Returns:

true if type is refTo(generic), false else
