Enum BenchmarkColumnSchema.ValueDistribution

java.lang.Object

java.lang.Enum<BenchmarkColumnSchema.ValueDistribution>

io.druid.benchmark.datagen.BenchmarkColumnSchema.ValueDistribution

All Implemented Interfaces:

Serializable, Comparable<BenchmarkColumnSchema.ValueDistribution>

Enclosing class:

BenchmarkColumnSchema

public static enum BenchmarkColumnSchema.ValueDistribution
extends Enum<BenchmarkColumnSchema.ValueDistribution>

SEQUENTIAL: Generate integer or enumerated values in sequence. Not random. DISCRETE_UNIFORM: Discrete uniform distribution, generates integers or enumerated values. ROUNDED_NORMAL: Discrete distribution that rounds sample values from an underlying normal distribution ZIPF: Discrete Zipf distribution. Lower numbers have higher probability. Can also generate Zipf distribution from a list of enumerated values. ENUMERATED: Discrete distribution, generated from lists of values and associated probabilities. NORMAL: Continuous normal distribution. UNIFORM: Continuous uniform distribution.

Method Detail

values

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

Returns:

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

valueOf

public static BenchmarkColumnSchema.ValueDistribution 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
