Constructor & Destructor Documentation

◆ Resource()

Resource::Resource	(	Resource *	Parent,
		RIFF::List *	lstResource
	)

protected

Constructor.

Initializes the 'Resource' object with values provided by a given INFO list chunk and a DLID chunk (the latter optional).

Parameters

Parent	- pointer to parent 'Resource', NULL if this is the toplevel 'Resource' object
lstResource	- pointer to an INFO list chunk

Member Function Documentation

◆ CopyAssign()

void Resource::CopyAssign ( const Resource * orig )

virtual

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

Parameters

orig	- original Resource object to be copied from

Referenced by DLS::Region::CopyAssign(), DLS::Sample::CopyAssignCore(), and DLS::Instrument::DeleteChunks().

◆ DeleteChunks()

void Resource::DeleteChunks ( )

virtual

Remove all RIFF chunks associated with this Resource object.

At the moment Resource::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.

Reimplemented in DLS::Instrument, DLS::Region, and DLS::Sample.

Definition at line 555 of file DLS.cpp.

Referenced by DLS::Sample::DeleteChunks(), DLS::Region::DeleteChunks(), and DLS::Instrument::DeleteChunks().

◆ UpdateChunks()

void Resource::UpdateChunks ( progress_t * pProgress )

virtual

Update chunks with current Resource data.

Apply Resource data persistently below the previously given resource list chunk. This will currently only include the INFO data. The DLSID will not be applied at the moment (yet).

You have to call File::Save() to make changes persistent.

Parameters

pProgress - callback function for progress notification

Implements DLS::Storage.

Reimplemented in gig::File, gig::Instrument, gig::Region, gig::Sample, DLS::File, DLS::Instrument, DLS::Region, and DLS::Sample.
