You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: SharedTransform.m
    path of file: ./repos/hebi-matlab-examples/include/util
    
    the code of the file until where you have to start completion: %SHAREDTRANSFORM enables sharing of a 4x4 transform across processes.
%   SHAREDTRANSFORM(name) provides access to a 4x4 transform that can be
%   shared across processes, e.g., across multiple MATLAB instances. This
%   is done using memory mapped files, which results in practically zero
%   overhead.
%   
%   Notes:
% 
%   -) Memory mapping requires a binary file b
    
function delete(this)
            
            % unmap memory
            this.file = [];
            
            % give up lock and try to delete file. Note that we disable
            % warnings, as only the last one has permission to actually
            % delete the file.
            fclose(this.fileLock);
            warning('off', 'MATLAB:DELETE:Permission');
            delete(this.store);
            warning('on', 'MATLAB:DELETE:Permission');
            
        end
        
        function T = getTransform(this)
            T = this.file.Data.T(1:4,1:4); % force a copy
        end
