First Non Empty Or Default¶
Class: FirstNonEmptyOrDefaultBlockV1
Takes input data which may not be present due to filtering or conditional execution and fills with default value to make it compliant with further processing.
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/first_non_empty_or_default@v1to add the block as
as step in your workflow.
Properties¶
| Name | Type | Description | Refs |
|---|---|---|---|
name |
str |
Enter a unique identifier for this step.. | ❌ |
default |
Any |
Default value that will be placed whenever there is no data found. | ❌ |
The Refs column marks possibility to parametrise the property with dynamic values available
in workflow runtime. See Bindings for more info.
