Method Details
-
asType
TypeMirror asType()Returns the type of this variable. Note that the types of variables range over many kinds of types, including primitive types, declared types, and array types, among others. -
getConstantValue
Object getConstantValue()Returns the value of this variable if this is afinal
field initialized to a compile-time constant. Returnsnull
otherwise. The value will be of a primitive type or aString
. If the value is of a primitive type, it is wrapped in the appropriate wrapper class (such asInteger
).Note that not all
final
fields will have constant values. In particular,enum
constants are not considered to be compile-time constants. To have a constant value, a field's type must be either a primitive type orString
.- Returns:
- the value of this variable if this is a
final
field initialized to a compile-time constant, ornull
otherwise - See Java Language Specification:

getSimpleName
Name getSimpleName()Returns the simple name of this variable element.For method and constructor parameters, the name of each parameter must be distinct from the names of all other parameters of the same executable. If the original source names are not available, an implementation may synthesize names subject to the distinctness requirement above.
For variables, the name of each variable is returned, or an empty name if the variable is unnamed.
- Specified by:
getSimpleName
in interfaceElement
- Returns:
- the simple name of this variable element
- See Also:
-
getEnclosingElement
Element getEnclosingElement()Returns the enclosing element of this variable. The enclosing element of a method or constructor parameter is the executable declaring the parameter.- Specified by:
getEnclosingElement
in interfaceElement
- Returns:
- the enclosing element of this variable
- See Also:
-
isUnnamed
default boolean isUnnamed()isUnnamed
is a reflective preview API of the Java platform.Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.Returnstrue
if this is an unnamed variable andfalse
otherwise.- Implementation Requirements:
- The default implementation of this method calls
getSimpleName()
and returnstrue
if the result is empty andfalse
otherwise. - Returns:
true
if this is an unnamed variable andfalse
otherwise- See Java Language Specification:
