                        int  usd_isrelationship(<stage>stage, string primpath, string name)
                    
                    
                
            
This function checks whether the primitive has a relationship of a given name.
            
                <stage>
            
            
        
When running in the context of a node (such as a wrangle LOP), this argument can be an integer representing the input number (starting at 0) to read the stage from. The integer is equivalent to the string form referencing a particular input, e.g., “opinput:0”.
You can also use this argument to refer to a USD file (e.g., “/path/to/file.usd”), or to another LOP node’s cooked stage using the op: as the path prefix (e.g., “op:/stage/lop_node”).
            
                primpath
The path to the primitive.
            
                name
            
            
        
The relationship name.
Returns
1 if the primitive has such a relationship, or 0 otherwise.
Examples ¶
// Check if the cube has a relationship "some_relationship". int is_valid_relationship = usd_isrelationship(0, "/geo/cube", "some_relationship");
