Class CopyResourceElementsOperation

java.lang.Object

org.aspectj.org.eclipse.jdt.internal.core.JavaModelOperation

org.aspectj.org.eclipse.jdt.internal.core.MultiOperation

org.aspectj.org.eclipse.jdt.internal.core.CopyResourceElementsOperation

All Implemented Interfaces:

SuffixConstants, org.eclipse.core.resources.IWorkspaceRunnable, org.eclipse.core.runtime.ICoreRunnable, org.eclipse.core.runtime.IProgressMonitor

Direct Known Subclasses:

MoveResourceElementsOperation

public class CopyResourceElementsOperation
extends MultiOperation
implements SuffixConstants

This operation copies/moves/renames a collection of resources from their current container to a new container, optionally renaming the elements.

Notes:

• If there is already an resource with the same name in the new container, the operation either overwrites or aborts, depending on the collision policy setting. The default setting is abort.
• When a compilation unit is copied to a new package, the package declaration in the compilation unit is automatically updated.
• The collection of elements being copied must all share the same type of container.
• This operation can be used to copy and rename elements within the same container.
• This operation only copies compilation units and package fragments. It does not copy package fragment roots - a platform operation must be used for that.

Field Details

createdElements

protected ArrayList createdElements

The list of new resources created during this operation.

deltasPerProject

protected Map deltasPerProject

Table specifying deltas for elements being copied/moved/renamed. Keyed by elements' project(s), and values are the corresponding deltas.

parser

protected ASTParser parser

The ASTParser used to manipulate the source code of ICompilationUnit.

Constructor Details

CopyResourceElementsOperation

public CopyResourceElementsOperation(IJavaElement[] resourcesToCopy,
 IJavaElement[] destContainers,
 boolean force)

When executed, this operation will copy the given resources to the given containers. The resources and destination containers must be in the correct order. If there is > 1 destination, the number of destinations must be the same as the number of resources being copied/moved.

Method Details

getMainTaskName

protected String getMainTaskName()

Description copied from class: MultiOperation

Returns the name to be used by the progress monitor.

Specified by:

getMainTaskName in class MultiOperation

See Also:

• MultiOperation

getSchedulingRule

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

Overrides:

getSchedulingRule in class JavaModelOperation

prepareDeltas

protected void prepareDeltas(IJavaElement sourceElement,
 IJavaElement destinationElement,
 boolean isMove,
 boolean overWriteCU)

Sets the deltas to register the changes resulting from this operation for this source element and its destination. If the operation is a cross project operation

• On a copy, the delta should be rooted in the dest project
• On a move, two deltas are generated
  • one rooted in the source project
  • one rooted in the destination project
  • When a CU is being overwritten, the delta on the destination will be of type F_CONTENT

If the operation is rooted in a single project, the delta is rooted in that project

processDeltas

protected void processDeltas()

Process all of the changed deltas generated by this operation.

processElement

protected void processElement(IJavaElement element)
                       throws JavaModelException

Description copied from class: MultiOperation

Subclasses must implement this method to process a given IJavaElement.

Specified by:

processElement in class MultiOperation

Throws:

JavaModelException

See Also:

• This method delegates to processCompilationUnitResource or processPackageFragmentResource, depending on the type of element.

processElements

protected void processElements()
                        throws JavaModelException

Description copied from class: MultiOperation

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

Overrides:

processElements in class MultiOperation

Throws:

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

See Also:

• Overridden to allow special processing of JavaElementDeltas and fResultElements.

verify

protected IJavaModelStatus verify()

Possible failures:

• NO_ELEMENTS_TO_PROCESS - no elements supplied to the operation
• INDEX_OUT_OF_BOUNDS - the number of renamings supplied to the operation does not match the number of elements that were supplied.

Overrides:

verify in class JavaModelOperation

See Also:

• IJavaModelStatus

verify

protected void verify(IJavaElement element)
               throws JavaModelException

Description copied from class: MultiOperation

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

Specified by:

verify in class MultiOperation

Throws:

JavaModelException

See Also:

• MultiOperation
