Interface Summary
Interface	Description
Factory<T>	A Factory interface for schema-related objects for a specific Java type.
FieldValueGetter<ObjectT,ValueT>	*For internal use only; no backwards-compatibility guarantees.*
FieldValueGetterFactory	A factory interface for creating `FieldValueGetter` objects corresponding to a class.
FieldValueSetter<ObjectT,ValueT>	*For internal use only; no backwards-compatibility guarantees.*
FieldValueSetterFactory	A factory interface for creating `FieldValueSetter` objects corresponding to a class.
FieldValueTypeInformationFactory	Factory for vending type information for all fields of a class.
SchemaProvider	Concrete implementations of this class allow creation of schema service objects that vend a `Schema` for a specific type.
SchemaProviderRegistrar	`SchemaProvider` creators have the ability to automatically have their `schemaProvider` registered with this SDK by creating a `ServiceLoader` entry and a concrete implementation of this interface.
SchemaUserTypeCreator	A creator interface for user types that have schemas.
UserTypeCreatorFactory	A factory for `SchemaUserTypeCreator` objects.

Class Summary
Class	Description
AutoValueSchema	A `SchemaProvider` for AutoValue classes.
AutoValueSchema.AbstractGetterTypeSupplier	`FieldValueTypeSupplier` that's based on AutoValue getters.
AvroRecordSchema	A `SchemaProvider` for AVRO generated SpecificRecords and POJOs.
FieldAccessDescriptor	Used inside of a `DoFn` to describe which fields in a schema type need to be accessed for processing.
FieldTypeDescriptors	Utilities for converting between `Schema` field types and `TypeDescriptor`s that define Java objects which can represent these field types.
FieldValueTypeInformation	Represents type information for a Java type that will be used to infer a Schema type.
GetterBasedSchemaProvider	A `SchemaProvider` base class that vends schemas and rows based on `FieldValueGetter`s.
JavaBeanSchema	A `SchemaProvider` for Java Bean objects.
JavaBeanSchema.GetterTypeSupplier	`FieldValueTypeSupplier` that's based on getter methods.
JavaBeanSchema.JavaBeanSetterFactory	A factory for creating `FieldValueSetter` objects for a JavaBean object.
JavaBeanSchema.SetterTypeSupplier	`FieldValueTypeSupplier` that's based on setter methods.
JavaFieldSchema	A `SchemaProvider` for Java POJO objects.
JavaFieldSchema.JavaFieldTypeSupplier	`FieldValueTypeSupplier` that's based on public fields.
Schema	`Schema` describes the fields in `Row`.
Schema.Builder	Builder class for building `Schema` objects.
Schema.Field	Field of a row.
Schema.Field.Builder	Builder for `Schema.Field`.
Schema.FieldType	A descriptor of a single field type.
SchemaCoder<T>	`SchemaCoder` is used as the coder for types that have schemas registered.
SchemaRegistry	A `SchemaRegistry` allows registering `Schema`s for a given Java `Class` or a `TypeDescriptor`.
SchemaUserTypeConstructorCreator	And implementation of `SchemaUserTypeCreator` that uses a Java constructor.
