# [LocalBranch('dev'), LocalBranch('master')]This table shows what nodes can be in a graph. The Letters denote the filters for creation of the graph as the second positional argument to git_networkx.GitNX i.e. the nodes argument.
As shown in above examples, the DiGraph from GitNX can be filtered by checking isinstance against the Node Classes below or by filtering by a an instance of one of the classes.
Overall Node Class: GitNode
| Node kind | Letter | Node Class | Node kind | Letter | Node Class |
|---|---|---|---|---|---|
| blob | b | Blob | remote branch | r | RemoteBranch |
| tree | t | Tree | remote head | d | RemoteHead |
| commit | c | Commit | remote server | s | RemoteServer |
| local branch | l | LocalBranch | annotated tag | a | AnnotatedTag |
| local head | h | LocalHead | tag | g | Tag |
By default all nodes are added to the DiGraph.
# you can get your commits, branches and the head of your local repo simply with lch
