ABSOLUTE

public static final DsType ABSOLUTE

Is for counters which get reset upon reading.

COUNTER

public static final DsType COUNTER

Is for continuous incrementing counters like the ifInOctets counter in a router.

DERIVE

public static final DsType DERIVE

Will store the derivative of the line going from the last to the current value of the data source.

GAUGE

Method Detail

valueOf

public static DsType 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

values

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

Returns:

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