public enum NativeType extends Enum<NativeType>
NativeType defines the primitive types supported internally. Usually you will not use these types directly, and should instead use the standard types such asPointer
,NativeLong
, or any of the normal java types such asint
,short
. All other types are defined in terms of these primitive types.

values
public static NativeType[] 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 (NativeType c : NativeType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static NativeType 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 nameNullPointerException
- if the argument is null
