From: Roland Haeder Date: Thu, 15 May 2014 18:56:12 +0000 (+0200) Subject: Continued: X-Git-Url: https://git.mxchange.org/?p=core.git;a=commitdiff_plain;h=86efcb137a3a9a692018ace94bbe5057d23b6825 Continued: - added FileIoIterator class and rewrote BaseFileStack to use it. - added BaseIterator class from 'hub' project. - added SeekableFileIterator which extends SPLs SeekableIterator. - assertion added for above interface to make sure that 'file_io_iterator' is a valid instance.
