Enum Constant and Description
CREATE_GROUPS create groups, and use them
CREATE_GROUPS_LINEAR_GROUP_REFRESH USE_EXISTING_GROUPS with LINEAR refresh
CREATE_GROUPS_LINEAR_REFRESH USE_EXISTING_GROUPS with LINEAR refresh
DEFAULT allow the query engine to heuristically determine what should be done
LINEAR read the key group by columns linearly, adding each key to the aggregation state factory one at a time
LINEAR_GROUPS read the key group by columns linearly, but create groups and add all indices to the state factory together
USE_EXISTING_GROUPS if there is a group, use it; otherwise operate as LINEAR_GROUPS

Method Detail

values

public static Table.ByStrategy[] 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.ByStrategy c : Table.ByStrategy.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.ByStrategy 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
