Method Detail

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

Performs the operation specific behavior. Subclasses must override.

Specified by:

executeOperation in class JavaModelOperation

Throws:

JavaModelException

See Also:

JavaModelOperation.executeOperation()

calculateEdit

public TextEdit calculateEdit(CompilationUnit unit,
                              TextEditGroup group)
                       throws JavaModelException

Parameters:

group -

Returns:

the edit or null if no sorting is required

Throws:

JavaModelException

verify

.

Overrides:

verify in class JavaModelOperation

Returns:

IJavaModelStatus
