BBox (Bounding box) class

Contents

Description

This is a handle heterogeneous super-class for the definition of bounding boxes.

A bounding box is used to limit the simulation domain. Particles that are outside the bounding box limits are removed from the simulation.

This super-class defines abstract methods that must be implemented in the derived sub-classes:

classdef BBox < handle & matlab.mixin.Heterogeneous

Constant values

    properties (Constant = true, Access = public)
        % Types of bounding box shapes
        RECTANGLE = uint8(1);
        CIRCLE    = uint8(2);
        POLYGON   = uint8(3);
    end

Public properties

    properties (SetAccess = public, GetAccess = public)
        type     uint8  = uint8.empty;    % flag for type of bounding box shape
        interval double = double.empty;   % time interval of activation (initial,final)
    end

Constructor method

    methods
        function this = BBox(type)
            if (nargin > 0)
                this.type = type;
            end
        end
    end

Default sub-class definition

    methods (Static, Access = protected)
        function defaultObject = getDefaultScalarElement
            defaultObject = BBox_Rectangle;
        end
    end
