Member Data Documentation

bool Node::dirty_

private

Dirty is true when the underlying file is out-of-date.

But note that Edge::outputs_ready_ is also used in judging which edges to build.

Definition at line 102 of file graph.h.

int Node::id_

private

A dense integer id for the node, assigned and used by DepsLog.

Definition at line 112 of file graph.h.

Edge* Node::in_edge_

private

The Edge that produces this Node, or NULL when there is no known edge to produce it.

Definition at line 106 of file graph.h.

TimeStamp Node::mtime_

private

Possible values of mtime_: -1: file hasn't been examined 0: we looked, and file doesn't exist >0: actual file's mtime.

Definition at line 97 of file graph.h.

Referenced by Stat().

vector<Edge*> Node::out_edges_

private

All Edges that use this Node as an input.
