How to use the java.util.TreeMap function in java

function(object){
if(Clazz.instanceOf(object,java.util.Map.Entry)){
var entry=object;
var v1=this.b$["java.util.TreeMap"].get(entry.getKey());
var v2=entry.getValue();
return v1==null?v2==null:v1.equals(v2);
}return false;
},"~O");
Clazz.defineMethod(c$,"iterator",

function(object){
return this.b$["java.util.TreeMap"].containsValue(object);
},"~O");
Clazz.overrideMethod(c$,"size",

function(){
return new java.util.TreeMap.UnboundedValueIterator(this.b$["java.util.TreeMap"]);
});
c$=$_P();

function(object){
return this.b$["java.util.TreeMap"].containsKey(object);
},"~O");
$_V(c$,"size",

function(object){
if($_O(object,java.util.Map.Entry)){
var entry=object;
