Constructor & Destructor Documentation

◆ Info()

DLS::Info::Info ( RIFF::List list)

Constructor.

Initializes the info strings with values provided by an INFO list chunk.

Parameters
list- pointer to a list chunk which contains an INFO list chunk

Definition at line 321 of file DLS.cpp.

References ArchivalLocation, Artists, Comments, Commissioned, Copyright, CreationDate, Engineer, Genre, RIFF::List::GetSubList(), Keywords, Medium, Name, Product, Software, Source, SourceForm, Subject, and Technician.

◆ ~Info()

DLS::Info::~Info ( )
virtual

Definition at line 348 of file DLS.cpp.

Member Function Documentation

◆ CopyAssign()

void DLS::Info::CopyAssign ( const Info orig)
virtual

Make a deep copy of the Info object given by orig and assign it to this object.

Parameters
orig- original Info object to be copied from

Definition at line 486 of file DLS.cpp.

References ArchivalLocation, Artists, Comments, Commissioned, Copyright, CreationDate, Engineer, Genre, Keywords, Medium, Name, Product, Software, Source, SourceForm, Subject, and Technician.

Referenced by DLS::Resource::CopyAssign().

◆ DeleteChunks()

void DLS::Info::DeleteChunks ( )
virtual

Remove all RIFF chunks associated with this Info object.

At the moment Info::DeleteChunks() does nothing. It is recommended to call this method explicitly though from deriving classes's own overridden implementation of this method to avoid potential future compatiblity issues.

See Storage::DeleteChunks() for details.

Implements DLS::Storage.

Definition at line 477 of file DLS.cpp.

◆ SetFixedStringLengths()

void DLS::Info::SetFixedStringLengths ( const string_length_t *  lengths)

Forces specific Info fields to be of a fixed length when being saved to a file.

By default the respective RIFF chunk of an Info field will have a size analogue to its actual string length. With this method however this behavior can be overridden, allowing to force an arbitrary fixed size individually for each Info field.

This method is used as a workaround for the gig format, not for DLS.

Parameters
lengths- NULL terminated array of string_length_t elements

Definition at line 362 of file DLS.cpp.

Referenced by gig::Sample::Sample().

◆ UpdateChunks()

void DLS::Info::UpdateChunks ( progress_t pProgress)
virtual

Update chunks with current info values.

Apply current INFO field values to the respective INFO chunks. You have to call File::Save() to make changes persistent.

Parameters
pProgress- callback function for progress notification

Implements DLS::Storage.

Definition at line 412 of file DLS.cpp.
