Enum StreamDeletionPolicy

java.lang.Object

java.lang.Enum<StreamDeletionPolicy>

io.lettuce.core.StreamDeletionPolicy

All Implemented Interfaces:

ProtocolKeyword, Serializable, Comparable<StreamDeletionPolicy>

public enum StreamDeletionPolicy
extends Enum<StreamDeletionPolicy>
implements ProtocolKeyword

Deletion policy for stream commands that handle consumer group references. Used with XDELEX, XACKDEL, and enhanced XADD/XTRIM commands.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ACKNOWLEDGED Only operates on entries that were read and acknowledged by all consumer groups.
DELETE_REFERENCES Removes all references to entries from all consumer groups' pending entry lists, effectively cleaning up all traces of the messages.
KEEP_REFERENCES Preserves existing references to entries in all consumer groups' PEL.

Enum Constant Detail

KEEP_REFERENCES

public static final StreamDeletionPolicy KEEP_REFERENCES

Preserves existing references to entries in all consumer groups' PEL. This is the default behavior similar to XDEL.

DELETE_REFERENCES

public static final StreamDeletionPolicy DELETE_REFERENCES

Removes all references to entries from all consumer groups' pending entry lists, effectively cleaning up all traces of the messages.

ACKNOWLEDGED

public static final StreamDeletionPolicy ACKNOWLEDGED

Only operates on entries that were read and acknowledged by all consumer groups.

Field Detail

bytes

public final byte[] bytes

Method Detail

values

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

Returns:

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

valueOf

public static StreamDeletionPolicy 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

getBytes

public byte[] getBytes()

Specified by:

getBytes in interface ProtocolKeyword

Returns:

byte[] encoded representation.
