Class GitIdentifiers.DirectoryEntry

java.lang.Object

org.apache.commons.codec.digest.GitIdentifiers.DirectoryEntry

All Implemented Interfaces:

Comparable<GitIdentifiers.DirectoryEntry>

Enclosing class:

GitIdentifiers

static class GitIdentifiers.DirectoryEntry
extends Object
implements Comparable<GitIdentifiers.DirectoryEntry>

Represents a single entry in a Git tree object.

A Git tree object encodes a directory snapshot. Each entry holds:

• a GitIdentifiers.FileMode that determines the Unix file mode (e.g. 100644 for a regular file),
• the entry name (file or directory name, without a path separator),
• the raw object id of the referenced blob or sub-tree.

Entries are ordered by compareTo(org.apache.commons.codec.digest.GitIdentifiers.DirectoryEntry) using Git's tree-sort rule: directory names are compared as if they ended with '/', so that foo/ sorts after foobar.
