Enum Constant Detail

DEFAULT

public static final Table.JoinStrategy DEFAULT

allow the query engine to heuristically determine what should be done

LINEAR

public static final Table.JoinStrategy LINEAR

linearly walk through the join key columns to create the keys

USE_EXISTING_GROUPS

public static final Table.JoinStrategy USE_EXISTING_GROUPS

if there is grouping information, use it; otherwise operate linearly

CREATE_GROUPS

public static final Table.JoinStrategy CREATE_GROUPS

if there is not an existing group, create it

Method Detail

values

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

Returns:

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

valueOf

public static Table.JoinStrategy 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

getGroupStrategy

public Table.GroupStrategy getGroupStrategy()
