Class GetterBasedSchemaProvider

java.lang.Object

org.apache.beam.sdk.schemas.GetterBasedSchemaProvider

All Implemented Interfaces:

java.io.Serializable, SchemaProvider

Direct Known Subclasses:

GetterBasedSchemaProviderV2

Deprecated.

new implementations should extend the GetterBasedSchemaProviderV2 class' methods which receive TypeDescriptors instead of ordinary Classes as arguments, which permits to support generic type signatures during schema inference

@Deprecated
public abstract class GetterBasedSchemaProvider
extends java.lang.Object
implements SchemaProvider

A SchemaProvider base class that vends schemas and rows based on FieldValueGetters.

Method Summary

Modifier and Type	Method and Description
boolean	equals(@Nullable java.lang.Object obj) Deprecated.
abstract java.util.List<FieldValueGetter>	fieldValueGetters(java.lang.Class<?> targetClass, Schema schema) Deprecated. new implementations should override fieldValueGetters(TypeDescriptor, Schema) and make this method throw an UnsupportedOperationException

Delegates to the fieldValueGetters(Class, Schema) for backwards compatibility, override it if you want to use the richer type signature contained in the TypeDescriptor not subject to the type erasure.

Delegates to the fieldValueTypeInformations(Class, Schema) for backwards compatibility, override it if you want to use the richer type signature contained in the TypeDescriptor not subject to the type erasure.
<T> SerializableFunction<Row,T>	fromRowFunction(TypeDescriptor<T> typeDescriptor) Deprecated. Given a type, returns a function that converts from a Row object to that type.
