Examples of org.eclipse.jgit.storage.file.PackIndexWriter

org.eclipse.jgit.storage.file.PackIndexWriter
Creates a table of contents to support random access by {@link PackFile}.
Pack index files (the .idx suffix in a pack file pair) provides random access to any object in the pack by associating an ObjectId to the byte offset within the pack where the object's data can be read.
