public class DeleteElementsOperation
extends MultiOperation

This operation deletes a collection of elements (and all of their children). If an element does not exist, it is ignored.

NOTE: This operation only deletes elements contained within leaf resources - that is, elements within compilation units. To delete a compilation unit or a package, etc (which have an actual resource), a DeleteResourcesOperation should be used.

Felddetails

childrenToRemove

protected Map childrenToRemove

The elements this operation processes grouped by compilation unit

Siehe auch:

• Keys are compilation units, values are IRegions of elements to be processed in each compilation unit.

parser

protected ASTParser parser

The ASTParser used to manipulate the source code of ICompilationUnit.

Konstruktordetails

DeleteElementsOperation

public DeleteElementsOperation(IJavaElement[] elementsToDelete,
 boolean force)

When executed, this operation will delete the given elements. The elements to delete cannot be null or empty, and must be contained within a compilation unit.

Methodendetails

getMainTaskName

protected String getMainTaskName()

Beschreibung aus Klasse kopiert: MultiOperation

Returns the name to be used by the progress monitor.

getSchedulingRule

protected org.eclipse.core.runtime.jobs.ISchedulingRule getSchedulingRule()

Setzt außer Kraft:

getSchedulingRule in Klasse JavaModelOperation

groupElements

protected void groupElements()
                      throws JavaModelException

Groups the elements to be processed by their compilation unit. If parent/child combinations are present, children are discarded (only the parents are processed). Removes any duplicates specified in elements to be processed.

Löst aus:

JavaModelException

processElement

protected void processElement(IJavaElement element)
                       throws JavaModelException

Deletes this element from its compilation unit.

Angegeben von:

processElements

protected void processElements()
                        throws JavaModelException

Beschreibung aus Klasse kopiert: MultiOperation

Processes all the IJavaElements in turn, collecting errors and updating the progress monitor.

Setzt außer Kraft:

processElements in Klasse MultiOperation

Löst aus:

JavaModelException - if one or several operation(s) was unable to be completed.

Siehe auch:

• This method first group the elements by ICompilationUnit, and then processes the ICompilationUnit.

verify

protected void verify(IJavaElement element)
               throws JavaModelException

Beschreibung aus Klasse kopiert: MultiOperation

This method is called for each IJavaElement before processElement. It should check that this element can be processed.

Angegeben von:
