public class SingleVariableDeclaration extends VariableDeclaration
SingleVariableDeclaration: { Modifier } Type Identifier { [] } [ = Expression ]For JLS3, the modifier flags were replaced by a list of modifier nodes (intermixed with annotations), and the variable arity indicator was added:
SingleVariableDeclaration: { ExtendedModifier } Type [ ... ] Identifier { [] } [ = Expression ]

Modifier and Type | Method and Description |
---|---|
int |
getExtraDimensions()
Returns the number of extra array dimensions over and above the
explicitly-specified type.
|
Expression |
getInitializer()
Returns the initializer of this variable declaration, or
null if there is none. |
int |
getModifiers()
Returns the modifiers explicitly specified on this declaration.
|
SimpleName |
getName()
Returns the name of the variable declared in this variable declaration.
|
Type |
getType()
Returns the type of the variable declared in this variable declaration,
exclusive of any extra array dimensions.
|
boolean |
isVarargs()
Returns whether this declaration declares the last parameter of
a variable arity method (added in JLS3 API).
|
List |
modifiers()
Returns the live ordered list of modifiers and annotations
of this declaration (added in JLS3 API).
|
static List |
propertyDescriptors(int apiLevel)
Returns a list of structural property descriptors for this node type.
|
void |
setExtraDimensions(int dimensions)
Sets the number of extra array dimensions over and above the
explicitly-specified type.
|
void |
setInitializer(Expression initializer)
Sets or clears the initializer of this variable declaration.
|
void |
setModifiers(int modifiers)
Deprecated.
In the JLS3 API, this method is replaced by
modifiers() which contains a list of a Modifier nodes. |
void |
setName(SimpleName variableName)
Sets the name of the variable declared in this variable declaration
to the given name.
|
void |
setType(Type type)
Sets the type of the variable declared in this variable declaration to
the given type, exclusive of any extra array dimensions.
|
void |
setVarargs(boolean variableArity)
Sets whether this declaration declares the last parameter of
a variable arity method (added in JLS3 API).

Note that the binding for the type Foo
in the vararg method
declaration void fun(Foo... args)
is always for the type as
written; i.e., the type binding for Foo
. However, if you
navigate from the method declaration to its method binding to the
type binding for its last parameter, the type binding for the vararg
parameter is always an array type (i.e., Foo[]
) reflecting
the way vararg methods get compiled.

For example, int x[][]
has a type of
int
and two extra array dimensions;
int[][] x
has a type of int[][]
and zero extra array dimensions. The two constructs have different
ASTs, even though there are really syntactic variants of the same
variable declaration.
