Enum StreamingFileSinkProgram

java.lang.Object

java.lang.Enum<StreamingFileSinkProgram>

StreamingFileSinkProgram

All Implemented Interfaces:

Serializable, Comparable<StreamingFileSinkProgram>

public enum StreamingFileSinkProgram
extends Enum<StreamingFileSinkProgram>

Test program for the StreamingFileSink.

Uses a source that steadily emits a deterministic set of records over 60 seconds, after which it idles and waits for job cancellation. Every record has a unique index that is written to the file.

The sink rolls on each checkpoint, with each part file containing a sequence of integers. Adding all committed part files together, and numerically sorting the contents, should result in a complete sequence from 0 (inclusive) to 60000 (exclusive).

Method Detail

values

public static StreamingFileSinkProgram[] 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 (StreamingFileSinkProgram c : StreamingFileSinkProgram.values())
    System.out.println(c);

Returns:

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

valueOf

public static StreamingFileSinkProgram 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

main

public static void main(String[] args)
                 throws Exception
