c
- the ResourceComparator to reverse.

add
public void add(ResourceComparator c)
Add the ResourceComparator to reverse.- Parameters:
c
- the ResourceComparator to add.
-
resourceCompare
protected int resourceCompare(Resource foo, Resource bar)
Compare two Resources.- Specified by:
resourceCompare
in classResourceComparator
- 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.

dieOnCircularReference
protected void dieOnCircularReference(java.util.Stack<java.lang.Object> stk, Project p) throws BuildException
Description copied from class:DataType
Check 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.checked
is true and set it to true on exit.- Overrides:
dieOnCircularReference
in classDataType
- Parameters:
stk
- the stack of references to check.p
- the project to use to dereference the references.- Throws:
BuildException
- on error.
