CheckConditionsOperation

public CheckConditionsOperation(Refactoring refactoring,
                                int style)

style - style to define which conditions to check. Must be one of INITIAL_CONDITONS, FINAL_CONDITIONS or ALL_CONDITIONS

Method Detail

run

public void run(IProgressMonitor pm)
         throws CoreException

Description copied from interface: ICoreRunnable

Executes this runnable.

The provided monitor can be used to report progress and respond to cancellation. If the progress monitor has been canceled, the runnable should finish its execution at the earliest convenience and throw an OperationCanceledException. A CoreException with a status of severity IStatus.CANCEL has the same effect as an OperationCanceledException.

Specified by:

run in interface ICoreRunnable

Specified by:

run in interface IWorkspaceRunnable

Parameters:

pm - a progress monitor, or null if progress reporting and cancellation are not desired. The monitor is only valid for the duration of the invocation of this method. Callers may call IProgressMonitor.done() after this method returns or throws an exception, but this is not strictly required.

Throws:

CoreException - if this operation fails

getStatus

public RefactoringStatus getStatus()

Returns the outcome of the operation or null if an exception has occurred while performing the operation or if the operation hasn't been performed yet.

Returns:

the RefactoringStatus of the condition checking

getRefactoring

public Refactoring getRefactoring()

Returns the operation's refactoring

Returns:

the operation's refactoring

getStyle

public int getStyle()

Returns the condition checking style.

Returns:

the condition checking style
