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: MultiplexPIn.m
    path of file: ./repos/BRAPH-2/braph2/measures
    
    the code of the file until where you have to start completion: classdef MultiplexPIn < Measure
	%MultiplexPIn is the graph Multiplex In-Participation.
	% It is a subclass of <a href="matlab:help Measure">Measure</a>.
	%
	% The Multiplex In
    
function tag = getPropTag(pointer)
			%GETPROPTAG returns the tag of a property.
			%
			% TAG = Element.GETPROPTAG(PROP) returns the tag TAG of the 
			%  property PROP.
			%
			% TAG = Element.GETPROPTAG(TAG) returns TAG, i.e. the tag of 
			%  the property with tag TAG.
			%
			% Alternative forms to call this method are (POINTER = PROP or TAG):
			%  TAG = M.GETPROPTAG(POINTER) returns tag of POINTER of M.
			%  TAG = Element.GETPROPTAG(MultiplexPIn, POINTER) returns tag of POINTER of MultiplexPIn.
			%  TAG = M.GETPROPTAG(MultiplexPIn, POINTER) returns tag of POINTER of MultiplexPIn.
			%
			% Note that the Element.GETPROPTAG(M) and Element.GETPROPTAG('MultiplexPIn')
			%  are less computationally efficient.
			%
			% See also getPropProp, getPropSettings, getPropCategory, getPropFormat,
			%  getPropDescription, getPropDefault, checkProp.
