Enum Constant Summary

Enum Constants

Enum Constant and 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.

Method Summary

Modifier and Type	Method and Description
static StatsLevel	getStatsLevel(byte value) Get StatsLevel by byte value.
byte	getValue() Returns the byte value of the enumerations value.
static StatsLevel	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static StatsLevel[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

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 Detail

values

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

Returns:

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

valueOf

public static StatsLevel 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

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:

java.lang.IllegalArgumentException - if an invalid value is provided.
