MappedFile Class

MappedFile is a utility class to read files on a file system. Because MappedFile file is derived from pdftron.Filters.Filter you can directly chain MappedFile objects to other 'pdftron.Filters'. MappedFile objects support random access to files using the Seek method. Seek allows the read/write position to be moved to any position within the file. This is done through a shared memory mapped chunk manager. The byte offset is relative to the seek reference point, which can be the beginning, the current position, or the end of the underlying file, as represented by the three properties of the Filter.ReferencePos class. MappedFile objects are thread-safe, meaning separate copies of a MappedFile can Seek to different locations in the file, without conflicting with one another. Disk files always support random access. At the time of construction, the CanSeek() property value is set to true or false depending on the underlying file type.
