Class DoFnSignature.Parameter.SchemaElementParameter

java.lang.Object

org.apache.beam.sdk.transforms.reflect.DoFnSignature.Parameter

org.apache.beam.sdk.transforms.reflect.DoFnSignature.Parameter.SchemaElementParameter

Enclosing class:

DoFnSignature.Parameter

public abstract static class DoFnSignature.Parameter.SchemaElementParameter
extends DoFnSignature.Parameter

Descriptor for a (@link Parameter} of type DoFn.Element where the type does not match the DoFn's input type. This implies that the input must have a schema that is compatible.
