Enum Constant Summary

Enum Constants

Enum Constant and Description
CUSTOM_BINS Custom bins: works with provided bins limits - todo
EQUAL_HEIGHT Equal height: bins have approximately the same size - todo - probably too costly to do it with MR task, better leave equal-width
EQUAL_WIDTH Equal width: (max - min) / num_bins, optimized.

Enum Constant Detail

EQUAL_WIDTH

public static final BinningStrategy EQUAL_WIDTH

Equal width: (max - min) / num_bins, optimized. Min is always excluded.

EQUAL_HEIGHT

public static final BinningStrategy EQUAL_HEIGHT

Equal height: bins have approximately the same size - todo - probably too costly to do it with MR task, better leave equal-width

CUSTOM_BINS

public static final BinningStrategy CUSTOM_BINS

Custom bins: works with provided bins limits - todo

Method Detail

values

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

Returns:

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

valueOf

public static BinningStrategy valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
