org.eclipse.core.commands.operations.IUndoableOperation.addContext()

Add the specified context to the operation. If a context equal to the specified context is already present, do not add it again. Note that determining whether a context is already present is based on equality, not whether the context matches ( {@link IUndoContext#matches(IUndoContext)}) another context.
@param context the context to be added
