of your first entry point finishes, the next entry point is called immediately.
XML
, we have to first parse the raw XML
text into XML DOM
structure. DOM
structure helps in the navigation of the data. XML
parser is located under XMLParser
class. XMLParser class consists of parse(String) static method which is called to parse the XML
and return a Document object. <someElement></someElement>

code resolves deferred binding configuarations (for example, browser detection) and use lookup table generated by GWT compiler to locate one of the .cache.html

code then creates a html hidden iframe, inserts that iframe into the host page's DOM, and loads the .cache.html
file into the same iframe..cache.html

file every time with the same name whenever a GWT application is compiled. So browser should always download the .nocache.js
