AttrCompare

java.lang.Object
- org.apache.xml.security.c14n.helper.AttrCompare

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator<org.w3c.dom.Attr>
```
public class AttrCompare
extends java.lang.Object
implements java.util.Comparator<org.w3c.dom.Attr>, 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).

    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).
    Specified by:

    Parameters:
    
    attr0 -
    
    attr1 -
    
    Returns:
    
    returns a negative integer, zero, or a positive integer as obj0 is less than, equal to, or greater than obj1
