org.eclipse.jgit.attributes.AttributesHandler

public class AttributesHandler
extends Object

The attributes handler knows how to retrieve, parse and merge attributes from the various gitattributes files. Furthermore it collects and expands macro expressions. The method getAttributes() yields the ready processed attributes for the current path represented by the TreeWalk

The implementation is based on the specifications in http://git-scm.com/docs/gitattributes

Since:

4.3

mergeAttributes

protected void mergeAttributes(@Nullable
                               AttributesNode node,
                               String entryPath,
                               boolean isDirectory,

Merges the matching node attributes for an entry path.

Parameters:

node - the node to scan for matches to entryPath

entryPath - the path to test. The path must be relative to this attribute node's own repository path, and in repository path format (uses '/' and not '\').

isDirectory - true if the target item is a directory.

result - that will hold the attributes matching this entry path. This method will NOT override any existing entry in attributes.
