public static enum HdrHistogram.ThreadSafetyMode
extends Enum<HdrHistogram.ThreadSafetyMode>

Describes the desired thread safety guarantees of the internally maintained HdrHistogram ValueRecorder implementation.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CONCURRENT_READS Used when writing to the histogram is done by a single thread, but reading from the histogram can be done concurrently.
CONCURRENT_READS_AND_WRITES Used when both reading from and writing to the histogram can be done concurrently.
UNSAFE Used when both reading from and writing to the histogram is done by a single thread or is synchronized externally.

Method Detail

values

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

Returns:

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

valueOf

public static HdrHistogram.ThreadSafetyMode 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
