void | Add (const T &node) |
Add a node. If the node is already present, has no effect. | |
bool | AddOrder (const T &node1, const T &node2) |
Add an ordering constraint (node1 precedes node2). | |
void | ClearMark (const T &node) |
Clear the "marked" flag for a given node. | |
void | ClearMark () |
Clear all "marked" flags. | |
bool | Contains (const T &node) |
Query a node's presence. | |
bool | Contains (const T &pre, const T &post) |
Query an edge's presence. Does not check for transitive connectivity. | |
csPartialOrder () | |
Create a partial order graph. | |
csPartialOrder (const csPartialOrder &other) | |
Copy constructor. | |
csPartialOrder (const csPartialOrder *other) | |
Copy constructor. | |
void | Delete (const T &node) |
Delete a node and all edges connected to it. | |
void | DeleteOrder (const T &node1, const T &node2) |
Remove an ordering constraint (node1 precedes node2) | |
const T | GetByIndex (size_t i) |
Return a node with a given index (0 through Size()-1) | |
const T | GetEnabled (T fail) |
Return an enabled node. | |
bool | HasEnabled () |
Return true if any node is enabled. | |
bool | IsEnabled (const T &node) |
Return true if all of the node's (zero or more) predecessors have been marked and the node itself has not. | |
bool | IsMarked (const T &node) |
Query whether a given node is "marked". | |
void | Mark (const T &node) |
Set the "marked" flag for a given node. | |
size_t | Size () |
Number of nodes in the graph. | |
void | Solve (csList< const T > &result) |
Produce a valid "solution" to the partial order graph, i.e., a sequence of nodes that violates no constraints. |
A generic finite partial order class.
A finite partial order is a graph with the following properties:
An insert of an edge which violates the third constraint will fail (return false and have no effect).
There must be a csHashComputer for type T.

csPartialOrder< T >::csPartialOrder | ( | ) | [inline] |
Create a partial order graph.
Definition at line 78 of file partialorder.h.
csPartialOrder< T >::csPartialOrder | ( | const csPartialOrder< T > & | other | ) | [inline] |
Copy constructor.
Definition at line 85 of file partialorder.h.
csPartialOrder< T >::csPartialOrder | ( | const csPartialOrder< T > * | other | ) | [inline] |
Copy constructor.
Definition at line 124 of file partialorder.h.
void csPartialOrder< T >::Add | ( | const T & | node | ) | [inline] |
Add a node. If the node is already present, has no effect.
Definition at line 131 of file partialorder.h.
bool csPartialOrder< T >::AddOrder | ( | const T & | node1, |
const T & | node2 | ||
) | [inline] |
Add an ordering constraint (node1 precedes node2).
Edge addition is not idempotent, i.e., if you add an edge three times, it must be removed three times before it will disappear from the graph.

void csPartialOrder< T >::ClearMark | ( | const T & | node | ) | [inline] |
Clear the "marked" flag for a given node.
Definition at line 346 of file partialorder.h.
void csPartialOrder< T >::ClearMark | ( | ) | [inline] |
Clear all "marked" flags.
Definition at line 357 of file partialorder.h.
bool csPartialOrder< T >::Contains | ( | const T & | node | ) | [inline] |
Query a node's presence.
Definition at line 142 of file partialorder.h.
bool csPartialOrder< T >::Contains | ( | const T & | pre, |
const T & | post | ||

Query an edge's presence. Does not check for transitive connectivity.
