This weekend I wrote a GIF parser, and refactored it a bit to use these classes (I do have a life--I did other things, too!). I've renamed some things and added some things (like setByteOrder() and BYTE_ORDER_MACHINE) and spent a couple hours writing an invisible buffering mechanism before determining that it actually made performance worse. :-D
Currently, and this is by no means finalized, but this is the structure: Zend_Parser_Interface Zend_Parser_DataSource_Interface Zend_File implements Zend_Parser_DataSource_Interface Zend_File_Parser_Abstract implements Zend_Parser_Interface My_Image_Gif extends Zend_File My_Image_Gif_Parser extends Zend_File_Parser_Abstract Theoretically, if there were something like Zend_String, it could implement Zend_Parser_DataSource_Interface and Zend_String_Parser could implement Zend_Parser_Interface. If you have suggestions on a better structure, I'd like to hear your thoughts. -Matt On Mon, April 2, 2007 3:26 am, Pádraic Brady wrote: > Spent part of the weekend implementing a file buffer class and parser for > yet another format (string, not binary).
