public class ForInStatement
For statement AST node type.
ForStatement: for ( [ ForInit ]; [ Expression ] ; [ ForUpdate ] ) Statement ForInit: Expression { , Expression } ForUpdate: Expression { , Expression }
Note: When variables are declared in the initializer
of a for statement such as "for (int a=1, b=2;;);
",
they should be represented as a single
VariableDeclarationExpression
with two fragments, rather than being split up into a pair
of expressions.

Special note: The JavaScript language does not allow a local variable declaration
to appear as the body of a for statement (they may only appear within a
block). However, the AST will allow a VariableDeclarationStatement
as the body of a ForStatement
. To get something that will
compile, be sure to embed the VariableDeclarationStatement
inside a Block
.
