Namespace: SnapObjects.Data

Assembly: SnapObjects.Data.dll

Syntax

public ISqlModelMapper Track(IMapperTrackable mapperTrackable, params object[] saveParms);

Parameters

mapperTrackable

The IMapperTrackable object to be tracked.

saveParms

The parameters used by the SaveChanges method of IMapperTrackable.

Returns

SnapObjects.Data.ISqlModelMapper

Returns the current ISqlModelMapper object, which can be used to execute other methods.

Examples

The following code example demonstrates how to track an IMapperTackable object. When saving the changes, it calls the SaveChanges method of the IMapperTrackable object, and commits the transaction at last.

using SnapObjects.Data;
using Appeon.ApiDoc.Models.School;
using System;

namespace Appeon.ApiDoc.ISqlModelMapperExamples
{
    public class TrackExample
    {
        private SchoolContext _context;

        public TrackExample(SchoolContext dataContext)
        {
            // Sets the data context.
            _context = dataContext;
        }

        public void Example4(IMapperTrackable newStudent)
        {
            var mapper = _context.SqlModelMapper;

            // Tracks the IMapperTrackable object for the new student.
            // There is no implement for IMapperTrackable in this library.
            mapper.Track(newStudent);

            // When saving the changes, it calls the SaveChanges method of the IMapperTrackable object. 
            var dbResult = mapper.SaveChanges();
        }
    }
}
