Execute¶

Session.Execute¶

Invokes a method in a managed library.

Currently supported library types include a Java jar or class file, a Common Language Runtime (.NET) dll, or a Python script. The input arguments should not contain KF attributes vector, point and frame Instead it should be passed as double[3], double[3] and double[16] respectively. For Python, only class bound staticmethods and global functions can be invoked. Behavior of other Python methods is unknown and thus not recconmended to invoke.

Signature Execute(libName, className, methodName, inputArgs)

NOTE: The full Unicode character set is not supported for this parameter. className (str) – Name of the class NOTE: The full Unicode character set is not supported for this parameter. methodName (str) – Name of the method to invoke NOTE: The full Unicode character set is not supported for this parameter. inputArgs (list of Variant) – Input arguments for .NET method

Return type:	Variant

New in version NX5.0.0.

License requirements: None.

ExecuteGrip¶

Session.ExecuteGrip¶

Call a grip subroutine.

The input argument is an array of objects of mixed types. Each element in the array corresponds to an input argument of the Grip program. The grip program receives its arguments via the UFARGS grip statement and the order of values in the array matches the order of variables in that statement.

Argument types supported in .NET and Java are Double, String and subclasses of TaggedObject as well as simple arrays of these types. These map to NUMBER, STRING and ENTITY types in Grip.

For arrays the caller should ensure that actual array passed in matches the length of the array declared in grip otherwise an error will occur.

The return value is a similar array containing the values of the Grip variables after the program has run.

C/C++ applications will need to use UF_call_grip for this purpose.

Signature ExecuteGrip(gripExecutable, inputArgs)

Parameters:	gripExecutable (str) – Name of Grip executable to run NOTE: The full Unicode character set is not supported for this parameter. inputArgs (list of Variant) – Input arguments for Grip subroutine
