Dennis Birkholz 95c41da020 Cache readFilter access and skip inner loops for empty/default readFilter (#773) ... For large XLSX files `Reader/Xlsx::readColumnsAndRowsAttributes()` performs a lot of calls to `$this->getReadFilter()` and `$this->getReadFilter()->readCell()` as `readCell()` is called twice for each (possibbly filled) cell. By ignoring calls to the DefaultReadFilter implementation (which always returns true), using no custom read filter will not incur any runtime penalty. The runtime penaltiy when using a custom read filter is reduced by a third by caching the read filter into a variable instead of using the getter method. Fixes issue #772.		2018-11-29 22:50:48 +01:00
