Construct and Work with Object Arrays
Object array construction and concatenation; heterogeneous arrays
Construct object arrays, reference objects and their properties from arrays, and design class hierarchies that support the formation of heterogeneous (mixed class) arrays.
|Create empty array of specified class|
|Superclass for heterogeneous array formation|
Build Object Arrays
- Construct Object Arrays
Build object arrays in the constructor and return the array as the output argument.
- Initialize Object Arrays
MATLAB® calls the class constructor with no arguments to initialize array elements with a default object.
- Initialize Arrays of Handle Objects
MATLAB uses a default object to initialize the empty elements of an array of handle objects.
- Empty Arrays
Empty arrays have no elements, but are of a certain class.
- Accessing Dynamic Properties in Arrays
Access dynamic properties in object arrays by referring to individual objects.
Object Converters and Class of Arrays
- Designing Heterogeneous Class Hierarchies
Heterogeneous arrays can contain objects of different class, but all objects in the array must derive from a common superclass.
- Heterogeneous Array Constructors
The class of a heterogeneous object array can change as you add array elements of different classes. You must ensure that constructors return objects that are the same class as the class defining the constructor.
