## CustomOperator.Debug

### Introduced

v4.0

### Description

Sets or returns the debug flags defined by the custom operator as a Long. When the value is not zero Softimage will log extra information about the operator's evaluation.
Note: You can read this property from within the update function of a custom operator but setting this property is blocked.

### C# Syntax

    // get accessor
    Int32 rtn = CustomOperator.Debug;
    // set accessor
    CustomOperator.Debug = Int32;

### Examples

#### JScript Example

    /*
             This example illustrates how to use the debug property to
             test an operator. The message Notify is sent to an operator
             to notify it that it's update ports are dirty. The RequestData
             and Evaluate messages are sent when the output is requested.
             The example below shows that the operator is only evaluated
             once even if the time is changed. This is because the inputs
             are not time dependent. Try setting a key on posy or
             enabling the CustomOperator.AlwaysEvaluate property, this
             forces the operator to re-evaluate on the second GetValue.
