◆ insert_sub_file()

void dismec::io::model::PartialModelIO::insert_sub_file ( const WeightFileEntry & data )

protected

Inserts a new sub-file entry into the metadata object.

Parameters

data	The specifications of the sub file to be added.

Exceptions

std::logic_error if data has weights for labels that overlap with already existing weights.

◆ label_lower_bound()

auto dismec::io::model::PartialModelIO::label_lower_bound ( label_id_t pos ) const

protected

Gets an iterator into the weight-file list that points to the first element whose starting label is larger than or equal to pos.

Assuming the partial model contains the weights for the label ranges [20, 50) and [100, 150). Then label_lower_bound(label) will return an iterator to the first element for all label values in the range [00, 20], the second for the range (20, 100] and an iterator to end for all others. This corresponds to the position in front of which a new sub-model for label pos would have to be inserted.
