Assertion Events

Declaration

Delegate Sub
  Mpx.Global.AssertionDelegate(file As String, 
                               line As UInt32, 
                               condition As String)

Public Shared Event
  Mpx.Global.AssertionEvent(file As String, 
                            line As UInt32, 
                            condition As String)

Description

AssertEvent is invoked when an internal MPX assertion occurs. After AssertionEvent has been invoked, an exception of type Mpx.AssertException is thrown.

AssertionEvent accepts delegates whose signatures match AssertionDelegate.

file	The source file where the assertion occurred.
line	The line where the assertion occurred.
condition	A text representation of the of the condition that failed.

Sample Code

The following code sets up an delegate to log MPX library assertions to a file using an undefined function LogToFile that takes a single argument of type String.


Public Sub MpxAssertHandler(ByVal file As String, 
                            ByVal line As UInt32, 
                            ByVal condition As String)
   LogToFile("Exception as " + file + ":" + line.ToString() + 
             ".  Condition: " + condition)
End Sub

Private Sub Form_Load(ByVal sender As System.Object, 
                      ByVal e As System.EventArgs) _Handles MyBase.Load
   AddHandler mpx.Global.AssertionEvent, AddressOf Me.MpxAssertHandler
End Sub
