public final class UseSupertypeDescriptor
extends JavaRefactoringDescriptor

Refactoring descriptor for the use supertype refactoring.

An instance of this refactoring descriptor may be obtained by calling RefactoringContribution.createDescriptor() on a refactoring contribution requested by invoking RefactoringCore.getRefactoringContribution(String) with the appropriate refactoring id.

Note: this class is not intended to be instantiated by clients.

Method Summary
protected  void populateArgumentMap()
          Populates the refactoring descriptor argument map based on the specified arguments.
 void setReplaceInstanceof(boolean replace)
          Determines whether 'instanceof' statements are considered as candidates to replace the subtype occurrence by one of its supertypes.
 void setSubtype(IType type)
          Sets the subtype of the refactoring.
 void setSupertype(IType type)
          Sets the supertype of the refactoring.
 RefactoringStatus validateDescriptor()
          Validates the refactoring descriptor with respect to the constraints imposed by the represented refactoring.

Clients must call this method to verify that all arguments have been correctly set and that they satisfy the constraints imposed by specific refactorings. Returning a refactoring status of severity RefactoringStatus.FATAL indicates that the refactoring descriptor cannot be used to create a refactoring instance.

Constructor Detail

UseSupertypeDescriptor

public UseSupertypeDescriptor()
Creates a new refactoring descriptor.

Method Detail

populateArgumentMap

protected void populateArgumentMap()
Populates the refactoring descriptor argument map based on the specified arguments.

Overrides:
populateArgumentMap in class JavaRefactoringDescriptor

setReplaceInstanceof

public void setReplaceInstanceof(boolean replace)
Determines whether 'instanceof' statements are considered as candidates to replace the subtype occurrence by one of its supertypes.

The default is to not replace the subtype occurrence.

Parameters:
replace - true to replace subtype occurrences in 'instanceof' statements, false otherwise

setSubtype

public void setSubtype(IType type)
Sets the subtype of the refactoring.

Occurrences of the subtype are replaced by the supertype set by setSupertype(IType) where possible.

Parameters:
type - the subtype to set

setSupertype

public void setSupertype(IType type)
Sets the supertype of the refactoring.

Occurrences of the subtype set by setSubtype(IType) are replaced by the supertype where possible.

Parameters:
type - the supertype to set

validateDescriptor

public RefactoringStatus validateDescriptor()
Validates the refactoring descriptor with respect to the constraints imposed by the represented refactoring.

Clients must call this method to verify that all arguments have been correctly set and that they satisfy the constraints imposed by specific refactorings. Returning a refactoring status of severity RefactoringStatus.FATAL indicates that the refactoring descriptor cannot be used to create a refactoring instance.

Overrides:
validateDescriptor in class JavaRefactoringDescriptor
Returns:
a refactoring status describing the outcome of the validation
