public interface IProgressMonitorWithBlocking extends IProgressMonitor
An extension to the IProgressMonitor interface for monitors that want to support feedback when an activity is blocked due to concurrent activity in another thread.When a monitor that supports this extension is passed to an operation, the operation should call
setBlockedwhenever it knows that it must wait for a lock that is currently held by another thread. The operation should continue to check for and respond to cancelation requests while blocked. When the operation is no longer blocked, it must callclearBlockedto clear the blocked state.This interface can be used without OSGi running.
Clients may implement this interface.

Indicates that this operation is blocked by some background activity. If a running operation ever callssetBlocked, it must eventually callclearBlockedbefore the operation completes.If the caller is blocked by a currently executing job, this method will return an
IJobStatusindicating the job that is currently blocking the caller. If this blocking job is not known, this method will return a plain informationalIStatusobject.- Parameters:
reason- an optional status object whose message describes the reason why this operation is blocked, ornullif this information is not available.- See Also:
