Enum Class 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.

Enum Constant Summary
Enum Constant | Description |

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
9.6.3 Repeatable Annotation Types
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.
