| bool | addMessageOp (Op *lpOp) |
| Called when an op in the tree enters an error state; returns true iff not in the set. | |
| bool | removeMessageOp (Op *lpOp) |
| Called when an op in the tree has its error cleared; returns true iff in the set. | |
| bool | hasMessage () const |
| Returns true if any op in this tree has a message set. | |
| bool | hasError () const |
| Returns true if any op in this tree has an error set. | |
| Op * | getFirstOpWithMessage () const |
| Returns the first op in the tree with a message set, or NULL if none do. | |
| Op * | getFirstOpWithError () const |
| Returns the first op in the tree with an error set, or NULL if none do. | |
| void | setNewRoot (Op *lpRoot) |
| Op * | getRoot () const |
| int | getDebugIndex () const |
| Information about an individual tree for debugging purposes. | |
| void | setDebugLabel (const std::string &lrLabel) |
| const std::string & | getDebugLabel () const |
| int | getNumMessageOps () const |
This class encapsulates a tree of ops to process, and associated states for that processing. It also manages a list of observers to notify when ops' error states change.
| void OpTree::setNewRoot | ( | Op * | lpRoot | ) |
Changes the tree root to a different op, updating references appropriately; not thread safe. Also clears aborted and cancelled flags.
