public class VariableDeclarationExpression extends Expression
This kind of node collects together several variable declaration fragments
(VariableDeclarationFragment
) into a single expression
(Expression
), all sharing the same modifiers and base type.
This type of node can be used as the initializer of a
ForStatement
, or wrapped in an ExpressionStatement
to form the equivalent of a VariableDeclarationStatement
.
VariableDeclarationExpression: { Modifier } Type VariableDeclarationFragment { , VariableDeclarationFragment }For JLS3, the modifier flags were replaced by a list of modifier nodes (intermixed with annotations):
VariableDeclarationExpression: { ExtendedModifier } Type VariableDeclarationFragment { , VariableDeclarationFragment }Provisional API: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
