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.
Schema.LogicalType<InputT,BaseT>	A LogicalType allows users to define a custom schema type.
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 creating SchemaUserTypeCreator objects from a user class and its inferred schema.

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.

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.
LogicalTypes	A collection of common Schema.LogicalType classes.
LogicalTypes.FixedBytes	A LogicalType representing a fixed-size byte array.
LogicalTypes.PassThroughLogicalType<T>	A base class for LogicalTypes that use the same Java type as the underlying base type.
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 Schemas for a given Java Class or a TypeDescriptor.
SchemaUserTypeConstructorCreator	And implementation of SchemaUserTypeCreator that uses a Java constructor.
