Python CatalogFunction Examples

Example #1

 def create_another_function():
     gateway = get_gateway()
     j_function = gateway.jvm.GenericCatalogFunction(
         "MyAnotherFunction", {})
     return CatalogFunction(j_function)

Example #2

 def create_function():
     gateway = get_gateway()
     j_function = gateway.jvm.CatalogFunctionImpl("MyFunction", {})
     return CatalogFunction(j_function)

Example #3
