Interface VariableElement

All Superinterfaces:
AnnotatedConstruct, Element
public interface VariableElement
extends Element

Represents a field, enum constant, method or constructor parameter, local variable, resource variable, or exception parameter.

Since:
1.6

Methods

getConstantValue

Object getConstantValue()

Returns the value of this variable if this is a final field initialized to a compile-time constant. Returns null otherwise. The value will be of a primitive type or a String. If the value is of a primitive type, it is wrapped in the appropriate wrapper class (such as Integer).

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 or String.

Returns:
the value of this variable if this is a final field initialized to a compile-time constant, or null otherwise

Elements.getConstantExpression(Object)

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.

Specified by:
getSimpleName in interface Element
Returns:
the simple name of this variable element
See Also:
PackageElement.getSimpleName(), ExecutableElement.getSimpleName(), TypeElement.getSimpleName(), getSimpleName()

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 interface Element
Returns:
the enclosing element of this variable
