Detailed Description

Create SignDocDocument objects.

Use getErrorMessage() to get more information after a function call failed.

As the error message is stored in this object, each thread should have its own instance of SignDocDocumentLoader or synchronization should be used.

Unless you need differently configured SignDocDocumentLoader objects, you should have only one SignDocDocumentLoader object per process (but see above). Loading font configuration files can be expensive, in particular if many fonts have to be scanned.

To be able to load documents, you have to register at least one document handler by passing a pointer to a SignDocDocumentHandler object to registerDocumentHandler().

Member Enumeration Documentation

enum de::softpro::doc::SignDocDocumentLoader::Flags

Flags for setFlags().

Enumerator:

f_map_into_memory

Map input files into memory.

If this flag is set, loadFromFile() and other functions will try to map their input file into memory. Doing that may improve performance (on Android, in particular) but read errors and truncating the file will crash the process.

This flag is just a hint and may be ignored.

enum de::softpro::doc::SignDocDocumentLoader::RemainingDays

Specify which expiry date shall be used by getRemainingDays().

Enumerator:

rd_product	Use the expiry date for the product.
rd_signing	Use the expiry date for signing documents.
