/**
* An enum describing the known shape specializations for stream abstractions.
* Each will correspond to a specific subinterface of {@link BaseStream}
* (e.g., {@code REFERENCE} corresponds to {@code Stream}, {@code INT_VALUE}
* corresponds to {@code IntStream}). Each may also correspond to
* specializations of value-handling abstractions such as {@code Spliterator},
* {@code Consumer}, etc.
*
* @apiNote
* This enum is used by implementations to determine compatibility between
* streams and operations (i.e., if the output shape of a stream is compatible
* with the input shape of the next operation).
*
* <p>Some APIs require you to specify both a generic type and a stream shape
* for input or output elements, such as {@link TerminalOp} which has both
* generic type parameters for its input types, and a getter for the
* input shape. When representing primitive streams in this way, the
* generic type parameter should correspond to the wrapper type for that
* primitive type.
