Class InMemoryRepository

java.lang.Object

org.eclipse.jgit.lib.Repository

org.eclipse.jgit.internal.storage.dfs.DfsRepository

org.eclipse.jgit.internal.storage.dfs.InMemoryRepository

All Implemented Interfaces:

java.lang.AutoCloseable

Direct Known Subclasses:

RefsUnreadableInMemoryRepository

public class InMemoryRepository
extends DfsRepository

Git repository stored entirely in the local process memory.

This implementation builds on the DFS repository by storing all reference and object data in the local process. It is not very efficient and exists only for unit testing and small experiments.

The repository is thread-safe. Memory used is released only when this object is garbage collected. Closing the repository has no impact on its memory.
