Class AttrCompare

java.lang.Object
  org.apache.axiom.c14n.helpers.AttrCompare

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator

public class AttrCompare
extends java.lang.Object
implements java.util.Comparator, java.io.Serializable

Compares two attributes based on the C14n specification.

• Namespace nodes have a lesser document order position than attribute nodes.
• An element's namespace nodes are sorted lexicographically by local name (the default namespace node, if one exists, has no local name and is therefore lexicographically least).
• An element's attribute nodes are sorted lexicographically with namespace URI as the primary key and local name as the secondary key (an empty namespace URI is lexicographically least).

• Namespace nodes have a lesser document order position than attribute nodes.
• An element's namespace nodes are sorted lexicographically by local name (the default namespace node, if one exists, has no local name and is therefore lexicographically least).

Specified by:

compare in interface java.util.Comparator

Parameters:

obj0 - casted org.apache.axiom.c14n.omwrapper.interfaces.Attr

obj1 - casted org.apache.axiom.c14n.omwrapper.interfaces.Attr

Returns:

returns a negative integer, zero, or a positive integer as obj0 is less than, equal to, or greater than obj1
