int usd_iscollection(<stage>stage, string collectionpath)
This function checks whether the given path points to an existing collection.
<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".
collectionpath
The path to the collection.
Returns
1
if the path points to an existing collection, or 0
otherwise.
Examples
// Check if cube has a collection "some_collection". string collection_path = usd_makecollectionpath(0, "/geo/cube", "some_collection"); int is_collection_existing = usd_iscollection(0, collection_path);
