Class NameNode.ExactMatchComparator

java.lang.Object

com.goldencode.p2j.schema.NameNode.ExactMatchComparator

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator<NameNode>

Direct Known Subclasses:

NameNode.AbbreviationComparator

Enclosing class:

NameNode

private static class NameNode.ExactMatchComparator
extends java.lang.Object
implements java.util.Comparator<NameNode>, java.io.Serializable

Comparator which requires the name portion of the NameNodes being compared lexically to match exactly for the nodes to be reported as equivalent (return value of 0 from compare method). This is used when looking up an unabbreviated name, or when determining the natural order of name nodes within a Namespace.

Method Detail

compare

public int compare(NameNode n1,
                   NameNode n2)

Resolves a comparison of two NameNode objects. After performing object reference identity check, and null checks, uses an exact lexical match of the nodes' names to determin equivalence.

Specified by:

compare in interface java.util.Comparator<NameNode>

Parameters:

n1 - First NameNode for comparison. If null, -1 is returned.

n2 - Second NameNode for comparison. If null, 1 is returned.

Returns:

0 if objects are considered equal by the rules of this comparator; -1 if n1 is considered less than n2; 1 if n1 is considered greater than n2.
