All Implemented Interfaces:

Serializable, Comparable<ClassType>

public enum ClassType
extends Enum<ClassType>

Enum to categorize Class objects.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ANNOTATION The class is an annotation type, e.g.
ARRAY The class is an array, such as String[].class or int[].class.
ENUM The class represents an enum, e.g.
ENUM_ENTRY The class is the synthetic class of an enum entry that anonymously extends the enum type.
INTERFACE The class is an interface, such as Collection.
PRIMITIVE The class is a primitive type such as double.class, or void.class.
PROXY_CLASS The class is a proxy class dynamically generated at runtime, such as those used in reflection or dynamic proxy mechanisms.
REGULAR_CLASS The class is a "regular" Java class, which typically means it was declared with the class or record keyword.

Method Summary

Modifier and Type	Method and Description
static ClassType	valueOf(String name) Returns the enum constant of this type with the specified name.
static ClassType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

ENUM

public static final ClassType ENUM

The class represents an enum, e.g. TimeUnit.

ENUM_ENTRY

public static final ClassType ENUM_ENTRY

The class is the synthetic class of an enum entry that anonymously extends the enum type. Although this class returns false for the Class.isEnum() method, it is assignable to the Enum type.
Example: NumericShaper.Range.ETHIOPIC.getClass()

ANNOTATION

public static final ClassType ANNOTATION

The class is an annotation type, e.g. Override. Classes that manually extend Annotation do not fall into this category.

Note that objects of annotation types have a corresponding proxy class; their class is categorized as PROXY_CLASS. Example:

{@code

PRIMITIVE

public static final ClassType PRIMITIVE

The class is a primitive type such as double.class, or void.class.

ARRAY

public static final ClassType ARRAY

The class is an array, such as String[].class or int[].class.

ArrayClassProperties

INTERFACE

public static final ClassType INTERFACE

The class is an interface, such as Collection.

PROXY_CLASS

public static final ClassType PROXY_CLASS

The class is a proxy class dynamically generated at runtime, such as those used in reflection or dynamic proxy mechanisms.

REGULAR_CLASS

public static final ClassType REGULAR_CLASS

The class is a "regular" Java class, which typically means it was declared with the class or record keyword. A class is considered a "regular class" by exclusion: it is a "regular class" if none of the other types of this enum apply to it.
Example: String

Note that nested classes and anonymous classes may also be considered "regular classes".

Method Detail

values

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

Returns:

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

valueOf

public static ClassType 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
