setLoadEagerly
public void setLoadEagerly(boolean pLoadEagerly) Instructs the reader wether it should read and cache alle thumbnails in sequence, during the first read operation.This is useful mainly if you need to read all the thumbnails, and you need them in random order, as it requires less repositioning in the underlying stream.
- Parameters:
pLoadEagerly
-true
if the reader should read all thumbs on first read
