public Object execute(Object obj,
JexlContext jc)
throws Exception
execute in class SimpleNodejc - the JexlContext to evaluate against.obj - not used.
Exception - on any error
public Object value(JexlContext jc)
throws Exception
value in class SimpleNodejc - the context to retrieve values from.
Exception - when evaluating the operands fails.
public static Object evaluateExpr(Object o,
Object loc)
throws Exception
2 is 'loc' and a is 'o'.
If o or loc are null, null is returned.
If o is a Map, o.get(loc) is returned.
If o is a List, o.get(loc) is returned. loc must resolve to an int value.
If o is an Array, o[loc] is returned. loc must resolve to an int value.
Otherwise loc is treated as a bean property of o.
o - an object to be accessed using the array operator or '.' operator.loc - the index of the object to be returned.
Exception - on any error.public String getIdentifierString()
ASTIdentifier.getIdentifierString().
