ValueType

Package: com.hypixel.hytale.server.npc.util.expression

public enum ValueType

Discriminant for the eight value types supported by the expression system. Used throughout the compiler, executor, and scope implementations to track operand types, validate assignments, and select instruction variants.

Enum Constants

Name	Description
VOID	No value / uninitialized.
NUMBER	double scalar.
STRING	String scalar.
BOOLEAN	boolean scalar.
EMPTY_ARRAY	Empty array literal ([]), assignable to any typed array.
NUMBER_ARRAY	double[] array.
STRING_ARRAY	String[] array.
BOOLEAN_ARRAY	boolean[] array.

Static Methods

Modifier	Return Type	Signature
public static	boolean	isAssignableType(@Nullable ValueType from, @Nullable ValueType to)
public static	boolean	isTypedArray(ValueType valueType)

isAssignableType returns true when from can be assigned to to. Both must be non-null and non-VOID, and either equal, or from is EMPTY_ARRAY and to is a typed array. isTypedArray returns true for BOOLEAN_ARRAY, NUMBER_ARRAY, and STRING_ARRAY.
