Interface Summary
Interface	Description
PCollectionView<T>	A `PCollectionView<T>` is an immutable view of a `PCollection` as a value of type `T` that can be accessed e.g.
PInput	The interface for things that might be input to a `PTransform`.
POutput	The interface for things that might be output from a `PTransform`.
PValue	A `PValue` is the interface to values that can be input and output from `PTransform`s.

Class Summary
Class	Description
KV<K,V>	An immutable key/value pair.
KV.OrderByKey<K extends Comparable<? super K>,V>	Orders the `KV` by the key.
KV.OrderByValue<K,V extends Comparable<? super V>>	Orders the `KV` by the value.
PBegin	`PBegin` is used as the "input" to a root `PTransform` that is the first operation in a `Pipeline`, such as `TextIO.Read` or `Create`.
PCollection<T>	A `PCollection<T>` is an immutable collection of values of type `T`.
PCollectionList<T>	A `PCollectionList<T>` is an immutable list of homogeneously typed `PCollection<T>`s.
PCollectionTuple	A `PCollectionTuple` is an immutable tuple of heterogeneously-typed `PCollection`s, "keyed" by `TupleTag`s.
PDone	`PDone` is the output of a `PTransform` that doesn't have a non-trival result, e.g., a Write.
POutputValueBase	A `POutputValueBase` is the abstract base class of `PTransform` outputs.
PValueBase	A `PValueBase` is an abstract base class that provides sensible default implementations for methods of `PValue`.
TimestampedValue<V>	An immutable (value, timestamp) pair.
TimestampedValue.TimestampedValueCoder<T>	A `Coder` for `TimestampedValue`.
TupleTag<V>	A `TupleTag` is a typed tag to use as the key of a heterogeneously typed tuple, like `PCollectionTuple`.
TupleTagList	A `TupleTagList` is an immutable list of heterogeneously typed `TupleTag`s.
TypeDescriptor<T>	A description of a Java type, including actual generic parameters where possible.
TypedPValue<T>	A `TypedPValue<T>` is the abstract base class of things that store some number of values of type `T`.

Package com.google.cloud.dataflow.sdk.values Description

Defines PCollection and other classes for representing data in a Pipeline.

A PCollection is an immutable collection of values of type T and is the main representation for data. A PCollectionTuple is a tuple of PCollections used in cases where PTransforms take or return multiple PCollections.

A PCollectionTuple is an immutable tuple of heterogeneously-typed PCollections, "keyed" by TupleTags. A PCollectionTuple can be used as the input or output of a PTransform taking or producing multiple PCollection inputs or outputs that can be of different types, for instance a ParDo with side outputs.

A PCollectionView is an immutable view of a PCollection that can be accessed from a DoFn and other user Fns as a side input.
