Enum StreamShape

java.lang.Object

java.lang.Enum<StreamShape>

java.util.stream.StreamShape

All Implemented Interfaces:

Serializable, Comparable<StreamShape>

public enum StreamShape
extends Enum<StreamShape>

An enum describing the known shape specializations for stream abstractions. Each will correspond to a specific subinterface of BaseStream (e.g., REFERENCE corresponds to Stream, INT_VALUE corresponds to IntStream). Each may also correspond to specializations of value-handling abstractions such as Spliterator, Consumer, etc.

Since:

1.8

Enum Constant Detail

REFERENCE

public static final StreamShape REFERENCE

The shape specialization corresponding to Stream and elements that are object references.

INT_VALUE

public static final StreamShape INT_VALUE

The shape specialization corresponding to IntStream and elements that are int values.

LONG_VALUE

public static final StreamShape LONG_VALUE

The shape specialization corresponding to LongStream and elements that are long values.

DOUBLE_VALUE

public static final StreamShape DOUBLE_VALUE

The shape specialization corresponding to DoubleStream and elements that are double values.

Method Detail

values

public static StreamShape[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (StreamShape c : StreamShape.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static StreamShape valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
