dotAssign

Class: matlab.mixin.indexing.RedefinesDot
Namespace: matlab.mixin.indexing

Customize handling of object index assignments that begin with dots

Since R2021b

Syntax

updatedObj = dotAssign(obj,indexOp,varargin)


Description

updatedObj = dotAssign(obj,indexOp,varargin) handles index assignment operations that begin with dots and index into fields that are inaccessible or nonexistent, such as obj.PrivateProp = 3 or obj.NotAProp{1} = 4. The indexOp object contains the indices of the values being changed, and varargin is a cell array of values to be assigned to those indexed locations. The method returns the updated object.

Input Arguments

obj — Object that implements customized dot indexing

object

Object that implements customized dot indexing by inheriting from matlab.mixin.indexing.RedefinesDot.

indexOp — Types of indexing operations and indices referenced

array of IndexingOperation objects

Types of indexing operations and indices referenced, specified as an array of IndexingOperation objects. For a dot assignment, the first object in the array has a Type property of Dot.

varargin — Values to be assigned in indexing operation

cell array

Values to be assigned in the indexing operation, specified as a cell array. For example, in the assignment operation obj.Prop = B, the value of varargin is {B}.

Output Arguments

updatedObj — Updated object after assignment operation

object

Updated object after assignment operation.
