What to extract is determined + * by an {@link ExtractionPolicy}. + * + *

For instance, a {@link ForInBodyExtractionPolicy} extracts the body of every for-in loop in + * the program, whereas a {@link CorrelatedPairExtractionPolicy} extracts pieces of code containing + * correlated property reads and writes of the same property.

+ * + *

As an example, consider the following function:

+ * 
+ *   function extend(dest, src) {
+ *     for(var p in src)
+ *       dest[p] = src[p];
+ *   }
+ *
+ *

Under both {@link ForInBodyExtractionPolicy} and {@link CorrelatedPairExtractionPolicy}, this + * should be transformed into

+ * 
+ *   function extend(dest, src) {
+ *     for(var p in src)
+ *       (function _forin_body_0(p) {
+ *         dest[p] = src[p];
+ *       })(p);
+ *   }
+ *
+ * + *

There are four issues to be considered here.

+ *
    + *
  • References to this: + *

    If the code to extract contains references to this, these references have to be + * rewritten; otherwise they would refer to the global object in the transformed code.

    + *

    We do this by giving the extracted function an extra parameter thi$, and rewriting + * this to thi$ within the extracted code.

    + *

    For instance,

    + * 
    + *   Object.prototype.extend = function(src) {
+ *     for(var p in src)
+ *       this[p] = src[p];
+ *   }
+ *
    + *

    becomes

    + * 
    + *   Object.prototype.extend = function(src) {
+ *     for(var p in src)
+ *       (function _forin_body_0(p, thi$) {
+ *         thi$[p] = src[p];
+ *       })(p, this);
+ *   }
+ *
    + *
    • + *
  • Local variable declarations: + *

    Local variable declarations inside the extracted code have to be hoisted to the enclosing function; + * otherwise they would become local variables of the extracted function instead.

    + *

    This is already taken care of by the translation from Rhino's AST to CAst.

    + *
    • + *
  • break,continue,return: + *

    A break or continue statement within the extracted loop body that refers + * to the loop itself or an enclosing loop would become invalid in the transformed code. A return + * statement would no longer return from the enclosing function, but instead from the extracted function.

    + *

    We transform all three statements into return statements returning an object literal with a + * property type indicating whether this is a 'goto' (i.e., break or return) + * or a 'return'. In the former case, the 'target' property contains an integer identifying the jump target; in + * the latter case, the 'value' property contains the value to return.

    + *

    The return value of the extracted function is then examined to determine whether it completed normally + * (i.e., returned undefined), or whether it returned an object indicating special control flow.

    + *

    For example, consider this code from MooTools:

    + * 
    + *   for(var style in Element.ShortStyles) {
+ *     if(property != style)
+ *       continue;
+ *     for(var s in Element.ShortStyles[style])
+ *       result.push(this.getStyle(s));
+ *     return result.join(' ');
+ *   }
+ *
    + *

    Under {@link ForInBodyExtractionPolicy}, this is transformed into

    + * 
    + *   for(var style in Element.ShortStyles) {
+ *     var s;
+ *     re$ = (function _forin_body_0(style, thi$) {
+ *       if(property != style)
+ *         return { type: 'goto', target: 1 };
+ *       for(s in Element.ShortStyles[style]) {
+ *         (function _forin_body_2(s) {
+ *           result.push(thi$.getStyle(s));
+ *         })(s);
+ *       }
+ *       return { type: 'return', value: result.join(' ') };
+ *     })(style, this);
+ *     if(re$) {
+ *       if(re$.type == 'return')
+ *         return re$.value;
+ *       if(re$.type == 'goto') {
+ *         if(re$.target == 1)
+ *           continue;
+ *       }
+ *     }
+ *   }
+ *
    + *

    Note that at the CAst level, break and continue are represented as goto + * statements, which simplifies the translation somewhat. The numerical encoding of jump targets does not matter + * as long as the extracted function and the fixup code agree on which number represents which label.

    + *
    • + *
  • Assignment to loop variable: + *

    The loop body may assign to the loop variable. If the variable is referenced after the loop, this assignment + * needs to be propagated back to the enclosing function in the extracted code.

    + *

    TODO: This is not handled at the moment.

    + *
    • + *
+ * + *

Finally, note that exceptions do not need to be handled specially.
