Detailed Description

The null mapper provides an implementation of the mapper interface that will assert on every single mapper call. This is useful for building new mappers from scratch as you an inherit from the null mapper and only implement mapper calls that are invoked.

◆ configure_context()

void Legion::Mapping::NullMapper::configure_context ( const MapperContext  ctx,
const Task &  task,
ContextConfigOutput &  output 
)
overridevirtual

Implements Legion::Mapping::Mapper.

◆ get_mapper_name()

const char * Legion::Mapping::NullMapper::get_mapper_name ( void  ) const
overridevirtual

Get Mapper Name

Specify a name that the runtime can use for referring to this mapper. This will primarily be used for providing helpful error messages so semantically meaningful names are encouraged. This mapper call must be immutable as it may be made before the synchronization model has been chosen.

Implements Legion::Mapping::Mapper.

overridevirtual

Implements Legion::Mapping::Mapper.

◆ handle_instance_collection()

void Legion::Mapping::NullMapper::handle_instance_collection ( const MapperContext  ctx,

Handle Instance Collection

If a mapper successfully subscribed to an instance then it will receive this callback from the runtime when the instance has been collected by the garbage collector.
