%% A test for class

%% Note

% ## Why use classes instead of functions
% ### Encapsulation
% ### Inheritance
% ### Polymorphism
% ### Abstraction 
% etc...

% ## rule of class
% 1 file can only contains 1 class definition
% Name of class should be the same as file name
% Only comments can exist before the class declaration

% ## < handle or not
% If class doesn't inherit from handle,
% than we need to use `test = test.get_pure_name();`
% instead of `test.get_pure_name();`

classdef ClassAlpha
    % all value of this class
    properties 
        name,
        pure_name
    end

    methods 
        % Construct function
        % notice that the name of the methon is equal to class name
        function obj = ClassAlpha()
            obj.name = 'Alpha_Romeo';
            obj.pure_name = '';
        end

        % Change the value of this class
        function obj = get_pure_name(obj)
            obj.pure_name = regexprep(obj.name, '_.*', '');
        end
    end

%% BlockInfo 用于获取块的所有属性

classdef BlockInfo < handle

% 属性
% block                 块的路径
% value_list            一个n*2的cell数组，第一列为属性，第二列为属性的值
%                       用get_param获取block的所有属性和它们的值
% value_list_content    value_list删除属性值为空的行之后的数组
properties
    block
    value_list
    value_list_content
end
methods 
    function obj = BlockInfo()
        obj.block = '';
        obj.value_list = '';
        obj.value_list_content = '';
    end

    %% 获得所有参数并存储于列表中
    function get_block_param(obj, block_path)
        if ~isempty(block_path)
            obj.block = block_path;
            params = get_param(block_path, 'ObjectParameters');
            fields = fieldnames(params);
            obj.value_list = cell(length(fields),2);
            for i = 1:length(fields)
                param = fields{i};
                value = get_param(block_path, param);
                obj.value_list{i,1} = param;
                obj.value_list{i,2} = value;
            end
        else
            disp('Check Input');
        end
    end

    %% 删除数值为空的选项
    % 这段代码的工作原理是这样的：
    % cellfun('isempty',cellArray(:,2))会返回一个逻辑数组，其中第二列为空的行为true，其余行为false。
    % ~操作符会将这个逻辑数组反转，使得第二列为空的行变为false，其余行变为true。
    % 最后，cellArray(~cellfun('isempty',cellArray(:,2)),:)会选择出那些第二列不为空的行。
    function reform_value_list(obj)
        cellArray = obj.value_list;
        cellArray = cellArray(~cellfun('isempty',cellArray(:,2)),:);
        obj.value_list_content = cellArray;
    end
end

end

% % 假设C是您的原始cell数组
% C = cell(10,1);

% % 创建三个空行
% emptyRows = cell(3,1);

% % 在第5行插入空行
% C = vertcat(C(1:4,:), emptyRows, C(5:end,:));
