Enum Constant Detail

HINT_SCALE

public static final Query.QueryHint HINT_SCALE

If present, the store can use a different LOD for the scale.

HINT_RESOLUTION

public static final Query.QueryHint HINT_RESOLUTION

If present, the store can simplify geometries according to the resolution.

Method Detail

values

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

Returns:

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

valueOf

public static Query.QueryHint 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
