Class Overview

ReflowProcessor is a processor that manages the requests of converting PDF page documents to reflow documents as HTML files. The output reflowable HTML file is identified by the requested page itself. For each PDF document that at least one of its page is requested for converting to reflow, a folder is created in cache directory. The folder name will be set to a unique ID of the PDF document (obtained from PDFUtil::GetUniqueIdString). Also, the output HTML file is obtained by the page object number. For example, the output HTML path of a PDF page with document ID of 2740180447,229945,WT1NOmJhyyH9xNqwbEbbOg== and object number of 123 will be ../trn_reflowcache/2740180447,229945,WT1NOmJhyyH9xNqwbEbbOg==/123.html The cache is placed in the sub-directory 'trn_reflowcache' of the PDFNet Resources folder, which can be set by calling PDFNet::SetPersistentCachePath. In the case the PersistentCachePath is not set the HTML files will be stored in the system temp path (PDFNet::GetSystemTempPath()). The cache will be used by any PDFNet process that uses the resource path. If more than one PDFNet process is running concurrently, the first process to acquire a lock on the cache will use it. Subsequent processes will not read or modify the cache.
