- All Implemented Interfaces:
- java.lang.Cloneable,- java.util.Comparator<Resource>
 
 public class Reverse extends ResourceComparator Reverses another ResourceComparator. If no nested ResourceComparator is supplied, the compared Resources' natural order will be reversed.- Since:
- Ant 1.7

Constructor Detail- 
Reversepublic Reverse() Default constructor.
 - 
Reversepublic Reverse(ResourceComparator c) Construct a new Reverse, supplying the ResourceComparator to be reversed.- Parameters:
- c- the ResourceComparator to reverse.

 - 
Method Detail- 
addpublic void add(ResourceComparator c) Add the ResourceComparator to reverse.- Parameters:
- c- the ResourceComparator to add.
 
 - 
resourceCompareprotected int resourceCompare(Resource foo, Resource bar) Compare two Resources.- Specified by:
- resourceComparein class- ResourceComparator
- Parameters:
- foo- the first Resource.
- bar- the second Resource.
- Returns:
- a negative integer, zero, or a positive integer as the first argument is greater than, equal to, or less than the second.
 
 - 
dieOnCircularReferenceprotected void dieOnCircularReference(java.util.Stack<java.lang.Object> stk, Project p) throws BuildExceptionDescription copied from class:DataTypeCheck to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).If one is included, throw a BuildException created by circularReference.This implementation is appropriate only for a DataType that cannot hold other DataTypes as children. The general contract of this method is that it shouldn't do anything if DataType.checkedis true and set it to true on exit.- Overrides:
- dieOnCircularReferencein class- DataType
- Parameters:
- stk- the stack of references to check.
- p- the project to use to dereference the references.
- Throws:
- BuildException- on error.
