int usd_isarraymetadata(<stage>stage, string path, string name)
This function checks whether the given metadata is an array.
<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”).
path
The path to the object. I.e, a primitive, an attribute, or a relationship.
name
The metadata name.
The name can be namespaced to acces values inside (possibly nested) VtDictionaries, such as custom data dictionary, e.g., “customData:name” or “customData:name:subname”. For non-namespaced names, the object schema needs to declare a given metadata for it to be accessible, e.g., “active” or “documentation”.
Returns
1 if the metadata exists and is an array, or 0 otherwise.
Examples ¶
// Check if the metadata is an array. int is_array = usd_isarraymetadata(0, "/geo/sphere", "documentation"); int is_array_too = usd_isarraymetadata(0, "/geo/cube", "customData:foo:bar");
