- abstract def bind(inputType: StructType): BoundFunction
Bind this function to an input type.
Bind this function to an input type.
If the input type is not supported, implementations must throw
UnsupportedOperationException
.For example, a "length" function that only supports a single string argument should throw UnsupportedOperationException if the struct has more than one field or if that field is not a string, and it may optionally throw if the field is nullable.
- inputType
a struct type for inputs that will be passed to the bound function
- returns
a function that can process rows with the given input type
- Exceptions thrown
UnsupportedOperationException
If the function cannot be applied to the input type
- abstract def description(): String
Returns Function documentation.
Returns Function documentation.
- returns
this function's documentation
- abstract def name(): String
A name to identify this function.
A name to identify this function. Implementations should provide a meaningful name, like the database and function name from the catalog.
