public enum PrimitiveArrayGenerators
extends Enum<PrimitiveArrayGenerators>

Provides generators for arrays of all Java primitive types. Each generator creates arrays of random length (1-128 elements) with random values appropriate for the primitive type.

Available generators:

• BOOLEAN - boolean[] arrays with random true/false values
• BYTE - byte[] arrays with random byte values
• CHAR - char[] arrays with random character values
• SHORT - short[] arrays with random short values
• INTEGER - int[] arrays with random integer values
• LONG - long[] arrays with random long values
• FLOAT - float[] arrays with random float values
• DOUBLE - double[] arrays with random double values

Example usage:

 // Generate arrays of different primitive types
 boolean[] booleans = (boolean[]) PrimitiveArrayGenerators.BOOLEAN.next();
 int[] integers = (int[]) PrimitiveArrayGenerators.INTEGER.next();
 
 // Get a generator for a specific primitive type
 var generator = PrimitiveArrayGenerators.resolveForType(int.class);
 int[] moreIntegers = (int[]) generator.next();
 

Implementation notes:

• All generators are thread-safe
• Array size is randomly chosen between 1 and 128 elements
• Values are generated using the corresponding primitive generators from Generators

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 PrimitiveArrayGenerators 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

next

an primitive array of the configured type, with the sizes 1-128

getType

public abstract Class<?> getType()

Returns:

the type of the primitive

resolveForType

public static PrimitiveArrayGenerators resolveForType(Class<?> primitiveType)

Returns a PrimitiveArrayGenerators for the given primitive type.

Parameters:

primitiveType - must not be null and a primitive type.

Returns:

the found PrimitiveArrayGenerators or throws an IllegalStateException if none could be found
