I've been using NodeTransformer.java as an example to write code which
walks through the JS Node tree. The one thing I'm held up with is
getting the names from an Object Literal. For example, in the
following JS:
var User = {
id : 123,
balance : 12.50,
name : "John Doe"
};
When I print the Node tree this is all I get:
[49] VAR
[-1] NAME User
[-1] OBJECTLIT
[-1] NUMBER
[-1] NUMBER
[-1] STRING John Do
It only returns the values. I would expect to get the names (id,
balance, name) and values Here's my Java code:
public static void readTree(ScriptOrFnNode tree, Node parent, int
indent){
Node node = null;
int funcIndex = 0;
// Generate indent padding
String padding = "";
for(int i = 0; i < indent; i++){
padding += "\t";
}
// Loop through sibling nodes
for (;;) {
// Get node
Node previous = null;
if (node == null) {
node = parent.getFirstChild();
} else{
previous = node;
node = node.getNext();
}
if (node == null) {
break;
}
int type = node.getType();
String val = "";
if(type == Token.STRING || type == Token.NAME || type ==
Token.FUNCTION){
val = node.getString();
}
System.out.println(padding +"["+ node.getLineno() +"] "+
Token.name(type) +" "+ val);
if(type == Token.FUNCTION){
ScriptOrFnNode func = tree.getFunctionNode(funcIndex++);
readTree(func, func, indent + 1);
}
// Get children
readTree(tree, node, indent + 1);
}
}
What am I doing wrong here?
