Interface VariableTree

All Superinterfaces:: StatementTree, Tree

public interface VariableTree extends StatementTree

A tree node for a variable declaration. For example:

  modifiers type name initializer ;
  modifiers type qualified-name.this

See Java Language Specification:: 8.3 Field Declarations
14.4 Local Variable Declarations
Since:: 1.6

Tree.Kind

Modifier and Type	Interface	Description
`static enum`	`Tree.Kind`	Enumerates all kinds of trees.

Method Summary

Modifier and Type	Method	Description
`ExpressionTree`	`getInitializer()`	Returns the initializer for the variable, or `null` if none.
`ModifiersTree`	`getModifiers()`	Returns the modifiers, including any annotations, on the declaration.
`Name`	`getName()`	Returns the name of the variable being declared or empty name if both the variable is unnamed and the preview features are enabled (Unnamed Patterns and Variables).
`ExpressionTree`	`getNameExpression()`	Returns the qualified identifier for the name being "declared".

Methods declared in interface Tree

accept, getKind

`<R,D> R`	`accept(TreeVisitor<R,D> visitor, D data)`	Accept method used to implement the visitor pattern.
`Tree.Kind`	`getKind()`	Returns the kind of this tree.

Method Details

getModifiers

ModifiersTree getModifiers()

Returns the modifiers, including any annotations, on the declaration.

Returns:: the modifiers

getName

Name getName()

Returns the name of the variable being declared or empty name if both the variable is unnamed and the preview features are enabled (Unnamed Patterns and Variables).

Returns:: the name

getNameExpression

ExpressionTree getNameExpression()

Returns the qualified identifier for the name being "declared". This is only used in certain cases for the receiver of a method declaration. Returns null in all other cases.

Returns:: the qualified identifier of a receiver declaration

getType

Tree getType()

Returns the type of the variable being declared..

API Note:

The type of the variable can be one of the following:

if the variable is declared using var, then the returned value is a VarTypeTree,
if the variable is a lambda parameter declared without a type (i.e. relying on type inferrence), then the returned value is null,
otherwise, the variable is declared with an explicit type, and the returned value is that type.

Returns:

the type of the variable being declared.

getInitializer

ExpressionTree getInitializer()

Returns the initializer for the variable, or null if none.

Returns:: the initializer
