Interface RefactoringDelta

All Known Implementing Classes:

DefaultRefactoringDelta

public interface RefactoringDelta

A refactoring delta contains an ordered collection of TextEdit. The order is based on the offset of those TextEdit objects: from the biggest offset to the smallest offset. This will allow the invoker to perform the refactoring by replacing the old values by the new values by following that order.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

hasTextEdits

boolean hasTextEdits()

Determines whether at least one TextEdit was added.

Returns:

true if there is at least one TextEdit; false otherwise

size

int size()

Returns the number of TextEdit objects that have been added.

Returns:

The count of TextEdit objects

textEdits

java.lang.Iterable<TextEdit> textEdits()

Returns the collection of TextEdit objects that have been added during one or several refactoring operations. The collection has been ordered where the TextEdit's offset are in reverse order, i.e. from the biggest to the smallest values.

Returns:

The ordered collection of TextEdit objects
