Enum Constants

Enum Constant	Description
ALL	Collect all stats, including measuring duration of mutex operations.
EXCEPT_DETAILED_TIMERS	Collect all stats except time inside mutex lock AND time spent on compression.
EXCEPT_TIME_FOR_MUTEX	Collect all stats except the counters requiring to get time inside the mutex lock.

Enum Constant Details

EXCEPT_DETAILED_TIMERS

public static final StatsLevel EXCEPT_DETAILED_TIMERS

Collect all stats except time inside mutex lock AND time spent on compression.

EXCEPT_TIME_FOR_MUTEX

public static final StatsLevel EXCEPT_TIME_FOR_MUTEX

Collect all stats except the counters requiring to get time inside the mutex lock.

ALL

public static final StatsLevel ALL

Collect all stats, including measuring duration of mutex operations.

If getting time is expensive on the platform to run, it can reduce scalability to more threads, especially for writes.

Method Details

values

public static StatsLevel[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static StatsLevel valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getValue

public byte getValue()

Returns the byte value of the enumerations value.

Returns:

byte representation

getStatsLevel

public static StatsLevel getStatsLevel(byte value)

Get StatsLevel by byte value.

Parameters:

value - byte representation of StatsLevel.

Returns:

StatsLevel instance.

Throws:

IllegalArgumentException - if an invalid value is provided.
