add
public void add(ResourceComparator c)
Add a delegate ResourceComparator.- Parameters:
c
- the next delegate ResourceComparator.
-
equals
public boolean equals(java.lang.Object o)
Equality method based on the vector of resources, or if a reference, the referred to object.- Specified by:
equals
in interfacejava.util.Comparator<Resource>
- Overrides:
equals
in classResourceComparator
- Parameters:
o
- the object to check against.- Returns:
- true if there is equality.
-
hashCode
public int hashCode()
Hashcode based on the rules for equality.- Overrides:
hashCode
in classResourceComparator
- Returns:
- a hashcode.
-
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 less than, equal to, or greater than the second.
-
dieOnCircularReference
