Class Description

                                                                      
 TMethodCall                                                          
                                                                      
 Method or function calling interface. Objects of this class contain  
 the (CINT) environment to call a global function or a method for an  
 object of a specific class with the desired arguments. This class is 
 espicially useful when a method has to be called more times for      
 different objects and/or with different arguments. If a function or  
 method needs to be called only once one better uses                  
 TInterpreter::Execute().                                             
                                                                      

 Default TMethodCall ctor. Use Init() to initialize the method call
 environment.

 Create a method invocation environment for a specific class, method and
 parameters. The parameter string has the form: "\"aap\", 3, 4.35".
 To execute the method call TMethodCall::Execute(object,...).
 This two step method is much more efficient than calling for
 every invocation TInterpreter::Execute(...).

 Create a global function invocation environment. The parameter
 string has the form: "\"aap\", 3, 4,35". To execute the
 function call TMethodCall::Execute(...).
 This two step method is much more efficient than calling for
 every invocation TInterpreter::Execute(...).

 Copy ctor.

 TMethodCall dtor.

 Initialize the method invocation environment. Necessary input
 information: the class, method name and the parameter string
 of the form "\"aap\", 3, 4.35".
 To execute the method call TMethodCall::Execute(object,...).
 This two step method is much more efficient than calling for
 every invocation TInterpreter::Execute(...).

 Initialize the function invocation environment. Necessary input
 information: the function name and the parameter string of
 the form "\"aap\", 3, 4.35".
 To execute the method call TMethodCall::Execute(...).
 This two step method is much more efficient than calling for
 every invocation TInterpreter::Execute(...).

 Initialize the method invocation environment. Necessary input
 information: the class, method name and the prototype string of
 the form: "char*,int,float".
 To execute the method call TMethodCall::Execute(object,...).
 This two step method is much more efficient than calling for
 every invocation TInterpreter::Execute(...).

 Initialize the function invocation environment. Necessary input
 information: the function name and the prototype string of
 the form: "char*,int,float".
 To execute the method call TMethodCall::Execute(...).
 This two step method is much more efficient than calling for
 every invocation TInterpreter::Execute(...).

 Return true if the method call has been properly initialized and is
 usable.

 Returns the TMethod describing the method to be executed. This takes
 all overriding and overloading into account (call TClass::GetMethod()).
 Since finding the method is expensive the result is cached.

 Execute the method (with preset arguments) for the specified object.

 Execute the method for the specified object and argument values.

 Execute the method (with preset arguments) for the specified object.

 Execute the method for the specified object and argument values.

 Execute the method (with preset arguments) for the specified object.

 Execute the method for the specified object and argument values.

 Execute the method (with preset arguments) for the specified object.

 Execute the method for the specified object and argument values.

 ParamArr is an array containing the function argument values.
 If nparam = -1 then paramArr must contain values for all function
 arguments, otherwise Nargs-NargsOpt <= nparam <= Nargs, where
 Nargs is the number of all arguments and NargsOpt is the number
 of default arguments.
