javax.lang.model.util.Elements.Origin

All Implemented Interfaces:

Serializable, Comparable<Elements.Origin>

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 Constants

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 type with the specified name.
static Elements.Origin[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

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 type.

See The 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 Type

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 Detail

values

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

Returns:

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

valueOf

public static Elements.Origin 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

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.
