Enum CQCommandType

java.lang.Object

java.lang.Enum<CQCommandType>

org.infinispan.query.clustered.commandworkers.CQCommandType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<CQCommandType>

public enum CQCommandType
extends java.lang.Enum<CQCommandType>

Types of CQWorker. Each type defines a different behavior for a ClusteredQueryCommand. The perform(org.infinispan.AdvancedCache<?, ?>, org.infinispan.query.impl.QueryDefinition, java.util.UUID, int) method is delegated to a CQWorker. This enum is more efficient to serialize than an actual CQWorker.

Since:

5.1

Method Detail

values

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

Returns:

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

valueOf

public static CQCommandType valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

valueOf

public static CQCommandType valueOf(int ordinal)

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:

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

Returns:

the enum constant with the specified name

Throws:

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

java.lang.NullPointerException - if the argument is null
