The IDL_Object::_overloadImpliedPrint function method can return a variable of any type to be printed out.

This method is designed to replicate the default behavior of objects that do not use operator overloading. As a result, object classes that do inherit from the IDL_Object class but that do not override this particular method will behave in the same manner as object classes that do not inherit from the IDL_Object class.

Tip: If you write an object class that inherits from IDL_Object and overloads this method, you can call the superclass method directly to achieve the default behavior for specific cases.


In most cases, this method is called indirectly by Implied Print. When called explicitly, the syntax is:

Result = Obj->[IDL_Object::]_overloadImpliedPrint( Varname )

Return Value

This method is called by Implied Print when it is called with an object that inherits from the IDL_Object class, but that does not implement its own _overloadImpliedPrint function method. The return value replicates the behavior of calling Implied Print with an object that does not inherit from the IDL_Object class.



A string containing the name of the variable supplied to Implied Print. If the variable was an expression then Varname will be equal to "<Expression>" You may want to use this variable name when constructing the print output for your object class.



Routine Signature

To overload this function method for an object class, implement a method with the following signature:

FUNCTION class::_overloadImpliedPrint, Varname

The return value of this function can be a variable of any type, which will be printed out instead of the default self object reference.
