Enum Class Elements.Origin

java.lang.Object
java.lang.Enum<Elements.Origin>
javax.lang.model.util.Elements.Origin
All Implemented Interfaces:
Serializable, Comparable<Elements.Origin>, Constable
Enclosing interface:
Elements
public static enum Elements.Origin extends Enum<Elements.Origin>
The origin of an element or other language model item. The origin of an element or item models how a construct in a program is declared in the source code, explicitly, implicitly, etc.

Note that it is possible additional kinds of origin values will be added in future versions of the platform.

See Java Language Specification:
13.1 The Form of a Binary

Nested Class Summary

Nested classes/interfaces declared in class java.lang.Enum

Enum.EnumDesc<E extends Enum<E>>

Enum Constant Summary

Enum Constant Description
EXPLICIT
Describes a construct explicitly declared in source code.
MANDATED
A mandated construct is one that is not explicitly declared in the source code, but whose presence is mandated by the specification.
SYNTHETIC
A synthetic construct is one that is neither implicitly nor explicitly declared in the source code.

Method Summary

Modifier and Type Method Description
boolean isDeclared()
Returns true for values corresponding to constructs that are implicitly or explicitly declared, false otherwise.
static Elements.Origin valueOf(String name)
Returns the enum constant of this class with the specified name.
static Elements.Origin[] values()
Returns an array containing the constants of this enum class, in the order they are declared.

Methods declared in class java.lang.Object

getClass, notify, notifyAll, wait, wait, wait

Enum Constant Details

EXPLICIT

public static final Elements.Origin EXPLICIT
Describes a construct explicitly declared in source code.

MANDATED

public static final Elements.Origin MANDATED
A mandated construct is one that is not explicitly declared in the source code, but whose presence is mandated by the specification. Such a construct is said to be implicitly declared. One example of a mandated element is a default constructor in a class that contains no explicit constructor declarations. Another example of a mandated construct is an implicitly declared container annotation used to hold multiple annotations of a repeatable annotation interface.
See Java Language Specification:
8.8.9 Default Constructor
8.9.3 Enum Members
8.10.3 Record Members
9.6.3 Repeatable Annotation Interfaces
9.7.5 Multiple Annotations of the Same Interface

SYNTHETIC

public static final Elements.Origin SYNTHETIC
A synthetic construct is one that is neither implicitly nor explicitly declared in the source code. Such a construct is typically a translation artifact created by a compiler.

Method Details

values

public static Elements.Origin[] values()
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 Elements.Origin 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

isDeclared

public boolean isDeclared()
Returns true for values corresponding to constructs that are implicitly or explicitly declared, false otherwise.
Returns:
true for EXPLICIT and MANDATED, false otherwise.
