Common function for a deferred workbench adapter for a debug element.

Method Detail

isContainer

public boolean isContainer()

Deprecated.

Description copied from interface: IDeferredWorkbenchAdapter

Returns whether this adapter may have children. This is an optimized method used by content providers to allow showing the [+] expand icon without having yet fetched the children for the element.

If false is returned, then the content provider may assume that this adapter has no children. If true is returned, then the job manager may assume that this adapter may have children.

Specified by:

isContainer in interface IDeferredWorkbenchAdapter

Returns:

trueif the adapter may have childen, and false otherwise.

getRule

public ISchedulingRule getRule(Object object)

Deprecated.

Description copied from interface: IDeferredWorkbenchAdapter

Returns the rule used to schedule the deferred fetching of children for this adapter.

Specified by:

getRule in interface IDeferredWorkbenchAdapter

Parameters:

object - the object whose children are being fetched

Returns:

the scheduling rule. May be null.

fetchDeferredChildren

public void fetchDeferredChildren(Object object,
                                  IElementCollector collector,
                                  IProgressMonitor monitor)

Deprecated.

Description copied from interface: IDeferredWorkbenchAdapter

Called by a job run in a separate thread to fetch the children of this adapter. The adapter should in return notify of new children via the collector. This is generally used when a content provider is getting elements.

It is good practice to check the passed in monitor for cancellation. This will provide good responsiveness for cancellation requests made by the user.

Specified by:

fetchDeferredChildren in interface IDeferredWorkbenchAdapter

Parameters:

object - the object to fetch the children for

collector - the collector to notify about new children. Should not be null.

monitor - a progress monitor that will never be null to support reporting and cancellation.
