int usd_hasapi(<stage>stage, string primpath, string api)
This function checks whether the given primitive adheres to the given API. I.e., whether that API has been applied to this primitive.
<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.
api
The name or an alias of the API schema to check.
Returns
1 if the primitive has the given API, or 0 otherwise.
Examples ¶
// Check if the primitive has a USD Geometry Model API applied. int has_geom_model_api_by_name = usd_hasapi(0, "/geo/sphere", "UsdGeomModelAPI"); int has_geom_model_api_by_alias = usd_hasapi(0, "/geo/sphere", "GeomModelAPI");
