Size-only mode tags the stream as only reading size data. More... | |

PageHandle::Ptr | createHandle (std::streamsize n) |
Creates a PageHandle to access the next. More... | |
void | read (PageHandle::Ptr &pageHandle, std::streamsize n, bool delayed=true) |
Takes a pageHandle and updates the referenced page with the current stream pointer position and if delayed is false performs an immediate read of the data. More... | |
