Method Detail

forLoop

public static Expr forLoop(SmallMethod method,
                           java.lang.String varName,
                           int start,
                           int end,
                           Expr body)
                    throws SmallJavaBuildingException
Builds a for loop.

Builds 

   for ([varName]=[start]; [varName]<[end]; [varName]++)
     [body]
into the given method.

Note that the local int variable must be defined before calling this method, like so: 

   // --- print the integers between 0 and 9, inclusive.
   method.local ("I", "i", new Expr.IntConst (0));
   method.add (SmallMacro.forLoop (method, "i", 0, 10, 
                                   SmallMacro.printLocal (method, "i")));

println

public static Expr println()
                    throws SmallJavaBuildingException
Calls Util.out.println ();

println

public static Expr println(java.lang.String msg)
                    throws SmallJavaBuildingException
Calls Util.out.println ("msg");

printField

public static Expr printField(java.lang.String className,
                              java.lang.String descriptor,
                              java.lang.String fieldName)
                       throws SmallJavaBuildingException
Calls Util.out.print, printing the given field reference.

printLocal

public static Expr printLocal(SmallMethod method,
                              java.lang.String fieldName)
                       throws SmallJavaBuildingException
Calls Util.out.print, printing the given local field reference.
