<cfscript>
foo = StructNew();
foo.a = "b";
foo.b = "a";
WriteOutput(foo.hashCode());
</cfscript>
Also, I have included more information on how the hashCode is generated
below.
public int hashCode()
Returns the hash code value for this map. The hash code of a map is
defined to be the sum of the hash codes of each entry in the map's
entrySet() view. This ensures that t1.equals(t2) implies that
t1.hashCode()==t2.hashCode() for any two maps t1 and t2, as required by
the general contract of Object.hashCode.
This implementation iterates over entrySet(), calling hashCode on each
element (entry) in the Collection, and adding up the results.
Specified by: hashCode in interface Map
Overrides: hashCode in class Object
Returns: the hash code value for this map.
See Also: Map.Entry.hashCode(), Object.hashCode(),
Object.equals(Object), Set.equals(Object)
