wt.part
Class PartStructureLineNumberComparator

java.lang.Object
  wt.part.PartStructureLineNumberComparator

All Implemented Interfaces:

Comparator

public class PartStructureLineNumberComparator

extends Object

implements Comparator

This Comparator can be used to compare the Line Number attribute of item 1 of an array, which should be a WTPartUsageLink, delegating the comparison to a sub-Comparator if neither object has a Line Number. Note that using this Comparator in a sort will result in all items without Line Numbers coming at the end.

Supported API: true

Extendable: false

Field Summary

(package private) static int	EQUAL
(package private) static int	GREATER_THAN
(package private) static int	LESS_THAN
private Comparator	subComparator

Constructor Summary

PartStructureLineNumberComparator(Comparator subComparator)
This constructor needs a subComparator to delegate the comparison to when it cannot perform the comparison itself.

Method Summary

int	compare(Object o1, Object o2) Compares the value of the Line Number attribute of wt.part.WTPartUsageLinkss using the getLineNumber method to extract the Line Numbers from the link objects and delegating the comparison to the sub-Comparator if neither object has a Line Number.
private LineNumber	getLineNumber(Object obj)

Constructor Detail

PartStructureLineNumberComparator

public PartStructureLineNumberComparator(Comparator subComparator)

This constructor needs a subComparator to delegate the comparison to when it cannot perform the comparison itself. For instance when neither has a LineNumber then the sub-Comparator, which might just compare based on Name or Number of the part, would be used.

Supported API: true

Extendable: false

compare

public int compare(Object o1,
