Enum Constant Detail

EQUALGRID

public static final GridType EQUALGRID

Partition the space to uniform grids

QUADTREE

public static final GridType QUADTREE

The Quad-Tree partitioning.

KDBTREE

public static final GridType KDBTREE

K-D-B-tree partitioning (k-dimensional B-tree)

ZORDER

public static final GridType ZORDER

Method Detail

values

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

Returns:

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

valueOf

public static GridType 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

getGridType

public static GridType getGridType(String str)

Gets the grid type.

Parameters:

str - the str

Returns:

the grid type
