algorithm
(将删除)指定度量数据分析的逻辑
以后的版本中将会删除度量仪表板用户界面、metricdashboard
函数、slmetric
包 API 以及相应的自定义项。有关详细信息,请参阅Migrating from Metrics Dashboard to Model Maintainability Dashboard。
说明
指定度量算法分析的逻辑。对于库链接和外部 MATLAB 文件组件,不调用以自定义形式创建的度量算法。
输入参数
Metric
— 新模型度量类
slmetric.metric.Metric
对象
为新度量定义的模型度量类。
Component
— 用于度量分析的组件
Advisor.component.Component
对象
用于度量分析的 Advisor.component.Component
的实例。
输出参量
Result
— 算法结果数据
slmetric.metric.Result
对象的数组
算法数据,以 slmetric.metric.Result
对象的数组形式返回。
示例
创建非虚拟模块计数的度量算法
此示例说明如何使用 algorithm
方法创建非虚拟模块计数度量。
通过使用 createNewMetricClass
函数,创建一个名为 nonvirtualblockcount
的度量类。该函数在当前工作文件夹中创建 nonvirtualblockcount.m
文件。
className = 'nonvirtualblockcount';
slmetric.metric.createNewMetricClass(className);
打开并编辑度量算法文件 nonvirtualblockcount.m
。文件包含一个空的度量算法方法。
edit(className);
将以下代码复制并粘贴到 nonvirtualblockcount.m
文件中。保存 nonvirtualblockcount.m
。该代码提供用于对非虚拟模块进行计数的度量算法。
classdef nonvirtualblockcount < slmetric.metric.Metric % nonvirtualblockcount calculate number of non-virtual blocks per level. % BusCreator, BusSelector and BusAssign are treated as non-virtual. properties VirtualBlockTypes = {'Demux','From','Goto','Ground', ... 'GotoTagVisibility','Mux','SignalSpecification', ... 'Terminator','Inport'}; end methods function this = nonvirtualblockcount() this.ID = 'nonvirtualblockcount'; this.Version = 1; this.CompileContext = 'None'; this.Description = 'Algorithm that counts nonvirtual blocks per level.'; this.ComponentScope = [Advisor.component.Types.Model, ... Advisor.component.Types.SubSystem]; end function res = algorithm(this, component) % create a result object for this component res = slmetric.metric.Result(); % set the component and metric ID res.ComponentID = component.ID; res.MetricID = this.ID; % use find_system to get all blocks inside this component blocks = find_system(getComponentSource(component), ... 'FollowLinks','on', 'SearchDepth', 1, ... 'Type', 'Block', ... 'FollowLinks', 'On'); isNonVirtual = true(size(blocks)); for n=1:length(blocks) blockType = get_param(blocks{n}, 'BlockType'); if any(strcmp(this.VirtualBlockTypes, blockType)) isNonVirtual(n) = false; else switch blockType case 'SubSystem' % Virtual unless the block is conditionally executed % or the Treat as atomic unit check box is selected. if strcmp(get_param(blocks{n}, 'IsSubSystemVirtual'), ... 'on') isNonVirtual(n) = false; end case 'Outport' % Outport: Virtual when the block resides within % any SubSystem block (conditional or not), and % does not reside in the root (top-level) Simulink window. if component.Type ~= Advisor.component.Types.Model isNonVirtual(n) = false; end case 'Selector' % Virtual only when Number of input dimensions % specifies 1 and Index Option specifies Select % all, Index vector (dialog), or Starting index (dialog). nod = get_param(blocks{n}, 'NumberOfDimensions'); ios = get_param(blocks{n}, 'IndexOptionArray'); ios_settings = {'Assign all', 'Index vector (dialog)', ... 'Starting index (dialog)'}; if nod == 1 && any(strcmp(ios_settings, ios)) isNonVirtual(n) = false; end case 'Trigger' % Virtual when the output port is not present. if strcmp(get_param(blocks{n}, 'ShowOutputPort'), 'off') isNonVirtual(n) = false; end case 'Enable' % Virtual unless connected directly to an Outport block. isNonVirtual(n) = false; if strcmp(get_param(blocks{n}, 'ShowOutputPort'), 'on') pc = get_param(blocks{n}, 'PortConnectivity'); if ~isempty(pc.DstBlock) && ... strcmp(get_param(pc.DstBlock, 'BlockType'), ... 'Outport') isNonVirtual(n) = true; end end end end end blocks = blocks(isNonVirtual); res.Value = length(blocks); end end end
