polyglot.ext.jl.ast.Term_c
polyglot.ext.jl.ast.Stmt_c
polyglot.ext.jl.ast.Loop_c
polyglot.ext.jl.ast.Do_c
A immutable representation of a Java language do statement.
It contains a statement to be executed and an expression to be tested
indicating whether to reexecute the statement.

public Type childExpectedType(Expr child,
AscriptionVisitor av)
Nodethis.
The expected type is determined by the context in that the child occurs
(e.g., for x = e, the expected type of e is
the declared type of x.
The expected type should impose the least constraints on the child's
type that are allowed by the parent node.
