Enum Constant Detail

ARRAY

public static final SpatialIndexType ARRAY

Array based spatial index (see ArraySpatialIndex.

KD_TREE

public static final SpatialIndexType KD_TREE

KD tree based spatial index (see KDTreeSpatialIndex).

BALL_TREE

public static final SpatialIndexType BALL_TREE

Method Detail

values

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

Returns:

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

valueOf

public static SpatialIndexType 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
