Class AddOnloadFunctionProcessor

java.lang.Object

org.apache.shindig.gadgets.js.AddOnloadFunctionProcessor

All Implemented Interfaces:

JsProcessor

public class AddOnloadFunctionProcessor
extends Object
implements JsProcessor

Adds code to call an onload function after the Javascript code has been interpreted. The onload function can be injected in one of two ways: 1. Via the &onload query parameter. This is used for "first-stage" JS when the method is directly injected. 2. Via ___jsl.c variable. This is set by "loader" JS which loads highly-cached 2nd-stage code that does not have onload injected.
