Enum Constant Detail

Sum

public static final DoubleSummary.Mode Sum

The aggregation mode is the summation function.

New retained value = previous retained value + incoming value

Min

public static final DoubleSummary.Mode Min

The aggregation mode is the minimum function.

New retained value = min(previous retained value, incoming value)

Max

public static final DoubleSummary.Mode Max

The aggregation mode is the maximum function.

New retained value = max(previous retained value, incoming value)

AlwaysOne

public static final DoubleSummary.Mode AlwaysOne

The aggregation mode is always one.

New retained value = 1.0

Method Detail

values

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

Returns:

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

valueOf

public static DoubleSummary.Mode 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
