Interface Summary

Interface	Description
CopyableValue<T>	Interface to be implemented by basic types that support to be copied efficiently.
Key<T>	Deprecated. The Key type is a relict of a deprecated and removed API and will be removed in future (2.0) versions as well.
NormalizableKey<T>	The base interface for normalizable keys.
ResettableValue<T extends Value>
Value	Basic value interface for types that act as serializable values.

Class Summary

Class	Description
BooleanValue	Boxed serializable and comparable boolean type, representing the primitive type boolean.
ByteValue	Boxed serializable and comparable byte type, representing the primitive type byte (signed 8 bit integer).
CharValue	Boxed serializable and comparable character type, representing the primitive type char.
DoubleValue	Boxed serializable and comparable double precision floating point type, representing the primitive type double.
Either<L,R>	This type represents a value of one two possible types, Left or Right (a disjoint union), inspired by Scala's Either type.
Either.Left<L,R>	A left value of Either
Either.Right<L,R>	A right value of Either
FloatValue	Boxed serializable and comparable single precision floating point type, representing the primitive type float.
IntValue	Boxed serializable and comparable integer type, representing the primitive type int.
JavaToValueConverter
ListValue<V extends Value>	Generic list base type for PACT programs that implements the Value and List interfaces.
LongValue	Boxed serializable and comparable long integer type, representing the primitive type long.
MapValue<K extends Value,V extends Value>	Generic map base type for PACT programs that implements the Value and Map interfaces.
Nothing	A type for (synthetic) operators that do not output data.
NullValue	Null base type for programs that implements the Key interface.
PojoTestUtils	Test utils around POJOs.
Record	The Record represents a multi-valued data record.
Row	A row is a fixed-length, null-aware composite type for storing multiple values in a deterministic field order.
RowUtils	Utilities to deal with Row instances.
SerializableOptional<T extends Serializable>	Serializable Optional.
ShortValue	Boxed serializable and comparable short integer type, representing the primitive type short.
StringValue	Mutable string data type that implements the Key interface.
