Constructor Details
- Interpreter
  
  protected Interpreter(Engine engine, JexlOptions opts, JexlContext aContext, Frame eFrame)
  
  Creates an interpreter.
  
  Parameters:
  
  engine - the engine creating this interpreter
  
  opts - the evaluation options, flags modifying evaluation behavior
  
  aContext - the evaluation context, global variables, methods and functions
  
  eFrame - the evaluation frame, arguments and local variables
- Interpreter
  
  protected Interpreter(Interpreter ii, JexlArithmetic jexla)
  
  Copy constructor.
  
  Parameters:

Method Details
- call
  
  protected Object call(JexlNode node, Object target, Object funcNode, ASTArguments argNode)
  
  Calls a method (or function).
  Method resolution is a follows: 1 - attempt to find a method in the target passed as parameter; 2 - if this fails, seeks a JexlScript or JexlMethod or a duck-callable* as a property of that target; 3 - if this fails, narrow the arguments and try again 1 4 - if this fails, seeks a context or arithmetic method with the proper name taking the target as first argument;
  *duck-callable: an object where a "call" function exists
  
  Parameters:
  
  node - the method node
  
  target - the target of the method, what it should be invoked upon
  
  funcNode - the object carrying the method or function or the method identifier

  the result of body evaluation
- evalIdentifier
  
  private Object evalIdentifier(ASTIdentifierAccess node)
  
  Evaluates an access identifier based on the 2 main implementations; static (name or numbered identifier) or dynamic (jxlt).
  
  Parameters:
