org.locationtech.geogig.repository.WorkingTree
A working tree is the collection of Features for a single FeatureType in GeoServer that has a repository associated with it (and hence is subject of synchronization).
It represents the set of Features tracked by some kind of geospatial data repository (like the GeoServer Catalog). It is essentially a "tree" with various roots and only one level of nesting, since the FeatureTypes held in this working tree are the equivalents of files in a git working tree.
- A WorkingTree represents the current working copy of the versioned feature types
- A WorkingTree has a Repository
- A Repository holds commits and branches
- You perform work on the working tree (insert/delete/update features)
- Then you commit to the current Repository's branch
- You can checkout a different branch from the Repository and the working tree will be updated to reflect the state of that branch
