Constructor Details

SortElementsOperation

public SortElementsOperation(int level,
 IJavaElement[] elements,
 int[] positions,
 Comparator comparator)

Constructor for SortElementsOperation.

Parameters:

level - the AST API level; one of the AST LEVEL constants

Method Details

getMainAmountOfWork

protected int getMainAmountOfWork()

Returns the amount of work for the main task of this operation for progress reporting.

isMalformed

protected boolean isMalformed(ASTNode node)

executeOperation

protected void executeOperation()
                         throws JavaModelException

Description copied from class: JavaModelOperation
