Examples of com.google.gwt.dev.js.ast.JsFor

com.google.gwt.dev.js.ast.JsFor
A for statement. If specified at all, the initializer part is either a declaration of one or more variables, in which case {@link #getInitVars()} is used, or an expression, in which case{@link #getInitExpr()} is used. In the latter case, the comma operator isoften used to create a compound expression.
Note that any of the parts of the for loop header can be null, although the body will never be null.
