Member Function Documentation

void DLS::Sampler::AddSampleLoop ( sample_loop_t pLoopDef)
inherited

Adds a new sample loop with the provided loop definition.

Parameters
pLoopDef- points to a loop definition that is to be copied

Definition at line 623 of file DLS.cpp.

References DLS::Sampler::pSampleLoops, DLS::Sampler::SampleLoops, and DLS::sample_loop_t::Size.

void DLS::Articulator::CopyAssign ( const Articulator orig)
virtualinherited

Not yet implemented in this version, since the .gig format does not need to copy DLS articulators and so far nobody used pure DLS instrument AFAIK.

Definition at line 236 of file DLS.cpp.

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

void Resource::CopyAssign ( const Resource orig)
virtualinherited

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

Definition at line 534 of file DLS.cpp.

References DLS::Info::CopyAssign(), and DLS::Resource::pInfo.

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

void DLS::Sampler::CopyAssign ( const Sampler orig)
virtualinherited

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

Parameters
orig- original Sampler object to be copied from

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

Make a (semi) deep copy of the Region object given by orig and assign it to this object.

Note that the sample pointer referenced by orig is simply copied as memory address. Thus the respective sample is shared, not duplicated!

Parameters
orig- original Region object to be copied from

void DLS::Sampler::DeleteSampleLoop ( sample_loop_t pLoopDef)
inherited

Deletes an existing sample loop.

Parameters
pLoopDef- pointer to existing loop definition
Exceptions
Exception- if given loop definition does not exist
