you say nothing about what the methods return; this is practically useless01:11 05-04-2010dsilva
Hi "wtf882",Too bad you didn't go to the trouble of reading the cheatsheet in PDF or the introduction in this page that says that the content in the page is just a "brief description" to the pdf.
On the PDF you can find what each method returns, among other things.
