Enum Constant Detail

OFF

public static final DistributedJoinMode OFF

Distributed joins is disabled. Local joins will be performed instead.

LOCAL_ONLY

public static final DistributedJoinMode LOCAL_ONLY

Distributed joins is enabled within local node only. NOTE: This mode is used with segmented indices for local sql queries. As in this case we need to make distributed join across local index segments and prevent range-queries to other nodes.

ON

public static final DistributedJoinMode ON

Distributed joins is enabled.

Method Detail

values

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

Returns:

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

valueOf

public static DistributedJoinMode 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

distributedJoinMode

public static DistributedJoinMode distributedJoinMode(boolean isLocal,
                                                      boolean distributedJoins)

Parameters:

isLocal - Query local flag.

distributedJoins - Query distributed joins flag.

Returns:

DistributedJoinMode for the query.
