Detailed Description

Resource profiling ptree populator.

This class provides functions to populate boost ptree with resource profiling data.

Example

To populate ptree with resource profiling data.

#include <kanzi/kanzi.hpp>
#include <kanzi/core.ui/resource/resource_profiling_ptree_populator.hpp>
#include <kanzi/core/cpp/iostream.hpp>
#include <kanzi/core/cpp/sstream.hpp>
#include <boost/property_tree/json_parser.hpp>

using namespace kanzi;

class ResourceProfilingPtreePopulatorExample : public Application
{
protected:
    void onShutdown() override
    {
        // Populate ptree with profiling data.
        ptree resourceProfilingDataTree = ResourceProfilingPtreePopulator::populatePropertyTree(getResourceManager()->getResourceProfiler());

        // Write ptree in json format to string stream.
        stringstream ss;
        boost::property_tree::json_parser::write_json(ss, resourceProfilingDataTree);

        // Boost json_writer considers "/" as escape character and adds "\" before each "/".
        // This affects how kzb urls are displayed.
        // The following code outputs json to cout replacing "\/" with "/".        
        string str(ss.str());
        string_view strView(str);
        while (!strView.empty())
        {
            size_t backSlashPos = strView.find("\\/");
            if (backSlashPos == string_view::npos)
            {
                cout << strView;
                strView = string_view();
                continue;
            }

            cout << strView.substr(0, backSlashPos);
            strView = strView.substr(backSlashPos + 1);
        }

        cout << "\n";
    }
};

Member Function Documentation

static ptree kanzi::ResourceProfilingPtreePopulator::populatePropertyTree ( const ResourceProfilingAttributes &  attributes )

static

Populates property tree with resource profiling attributes.

Parameters

attributes

The resource profiling attributes.

Returns

The property tree populated with resource profiling attributes.

static ptree kanzi::ResourceProfilingPtreePopulator::populatePropertyTree ( const ResourceProfilingContext &  context )

static

Populates property tree with resource profiling attributes of the context.

Parameters

context

The resource profiling context.

Returns

The property tree populated with resource profiling attributes of the context.

static ptree kanzi::ResourceProfilingPtreePopulator::populatePropertyTree ( const ResourceProfilingContextFactory &  factory )

static

Populates property tree with resource profiling attributes of the contexts stored in the context factory.

This function creates new unnamed ptree node for each context and calls populatePropertyTree() function to populate that ptree node with context attributes. The new ptree node is then added to propertyTree.

Parameters

factory

The resource profiling context factory.

Returns

The property tree populated with resource profiling attributes of the contexts stored in the context factory.

static ptree kanzi::ResourceProfilingPtreePopulator::populatePropertyTree ( const ResourceProfilingDataSample &  dataSample )

static

Populates property tree with attributes of resource profiling data sample.

Parameters

dataSample

The resource profiling data sample.

Returns

The property tree populated with attributes of resource profiling data sample.

static ptree kanzi::ResourceProfilingPtreePopulator::populatePropertyTree ( const ResourceProfilingDataSample::Factory &  factory )

static

Populates property tree with attributes of resource profiling data samples stored in the data sample factory.

This function creates new unnamed ptree node for each data sample and calls populatePropertyTree() function to populate that ptree node with data sample attributes. The new ptree node is then added to propertyTree.

Parameters

factory

The resource profiling data samples factory.

Returns

The property tree populated with attributes of resource profiling data samples stored in the data sample factory.

static ptree kanzi::ResourceProfilingPtreePopulator::populatePropertyTree ( const ResourceProfiler &  profiler )

static

Populates property tree with attributes of all the profiling data stored in profiler.

This function creates a new ptree node for each resource profiling context factory and calls the populatePropertyTree() function to populate that node with profiling data stored in context factory. The name of that ptree node is set to the name of the loading thread to which the resource profiling context factory belongs. Each context factory ptree node is then added as a child to the node named "ThreadContexts" which is in turn added as a child to the root of the resulting ptree.

This function creates a new ptree node named "ResourceProfilingDataSamples". That node is populated with the populatePropertyTree() function called for the profiling data sample factory owned by profiler. To access the profiling data sample factory use the ResourceProfiler::getResourceProfilingDataSampleFactory() function.

Parameters

profiler

The resource profiler.

Returns

The property tree populated with attributes of all the profiling data stored in profiler.
