Enum Constant Detail

WALL_CLOCK_TIME

public static final Counter.Type WALL_CLOCK_TIME

The elapsed time experienced by a user waiting for a task to complete

CPU_TIME

public static final Counter.Type CPU_TIME

The total time spent using a CPU for the current thread

USER_TIME

public static final Counter.Type USER_TIME

The total CPU time that the current thread has executed in user mode

SYSTEM_TIME

public static final Counter.Type SYSTEM_TIME

The time spent by the kernel to execute system level operations on behalf of the application

Method Detail

values

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

Returns:

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

valueOf

public static Counter.Type 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

toString

public String toString()

Overrides:

toString in class Enum<Counter.Type>

defaultDataFetchStrategy

public abstract long defaultDataFetchStrategy(TimeUnit targetTimeUnit)

Executes default data fetch strategy for the specific type.

Parameters:

targetTimeUnit - the time unit in which the data will be returned

Returns:

the default data strategy for this type, in the specified time unit
