Hi, Norris!
Currently omj.Node uses Hashtable to map int property types to
objects/integer. In my opinion this is very inefficient: to store single
int property it creates 5 objects: one for property Hahstable, 2 Integer
wrappers for property/value, array to sore Hahstable slots and Hashtable
slot itself. To fix this I added omj.UintMap class that can map
non-negative integers to objects or integers and modified omj.Node to
use it. The class is a hashtable implementation that uses one int[] and
one Object[] arrays to store keys/values and Object[] array is not
created if the map contains only integers.
To take full advantage of omj.UintMap code has to be modified to use
Node.getIntProp/Node.putIntProp to store int properties, but even in
this form it is a win.
I can provide patches to use Node.getIntProp/Node.putIntProp and UintMap
for InterpreterData.itsLineNumberTable if this is OK.
Regards, Igor
