DLS::File::File | ( | ) |
Constructor.
Default constructor, use this to create an empty DLS file. You have to add samples, instruments and finally call Save() to actually write a DLS file.

void DLS::File::UpdateChunks | ( | ) | [virtual] |
Apply all the DLS file's current instruments, samples and settings to the respective RIFF chunks.
You have to call Save() to make changes persistent.

Referenced by Save(), and gig::File::UpdateChunks().
void DLS::File::Save | ( | const String & | Path | ) | [virtual] |
Save changes to another file.
Make all changes persistent by writing them to another file. Caution: this method is optimized for writing to another file, do not use it to save the changes to the same file! Use Save() (without path argument) in that case instead! Ignoring this might result in a corrupted file!
After calling this method, this File object will be associated with the new file (given by Path) afterwards.
Path | - path and file name where everything should be written to |

References pRIFF, RIFF::File::Save(), and UpdateChunks().
void DLS::File::Save | ( | ) | [virtual] |
Save changes to same file.
Make all changes persistent by writing them to the actual (same) file. The file might temporarily grow to a higher size than it will have at the end of the saving process.

DLS::Exception | if any kind of DLS specific error occured |
