So, consider this filterchain : - * - * <filterchain> - * <stripphpcomments /> - * <linecontains> - * <contains value="foo"> - * </linecontains> - * <tabtospaces tablength="8" /> - * </filterchain> - * - * getAssembledReader will return a Reader object wich read on each - * of these filters. Something like this : ('->' = 'which read data from') : - * - * [TABTOSPACES] -> [LINECONTAINS] -> [STRIPPHPCOMMENTS] -> [FILEREADER] - * (primary reader) - * - * So, getAssembledReader will return the TABTOSPACES Reader object. Then - * each read done with this Reader object will follow this path. - * - * Hope this explanation is clear :) - * - * TODO: Implement the classPath feature. - * - * @author <a href="mailto:yl@seasonfive.com">Yannick Lecaillez</a> - * @version $Id$ - * @access public - * @package phing.filters.util -*/ -class ChainReaderHelper { - - /** Primary reader to wich the reader chain is to be attached */ - private $primaryReader = null; - - /** The site of the buffer to be used. */ - private $bufferSize = 8192; - - /** Chain of filters */ - private $filterChains = array(); - - /** The Phing project */ - private $project; - - /* - * Sets the primary reader - */ - function setPrimaryReader(Reader $reader) { - $this->primaryReader = $reader; - } - - /* - * Set the project to work with - */ - function setProject(Project $project) { - $this->project = $project; - } - - /* - * Get the project - */ - function getProject() { - return $this->project; - } - - /* - * Sets the buffer size to be used.
