WithCalledMemberOwner Code Mapping Condition

Description

Tests conditions against the owner of a method being called.

This means that for a method call:

  anInstance.foo();

The inner conditions of this element are tested against the anInstance part of the expression.

Properties

Property	Usage	Description
SubCondition	Required/Content property	The conditions to test on the left side of the invoked member owner.

Example

The following example captures the variable holding a reference calls to Microsoft.Phone.Maps.Controls.Map.SetView in order to transform them to calls to MapControl.TrySetView .

<MapUnit xmlns="clr-namespace:Mobilize.Mappers.Extensibility.Core;assembly=Mobilize.ExtensibleMappers"
         xmlns:map="clr-namespace:Mobilize.Mappers.Extensibility.Code;assembly=Mobilize.ExtensibleMappers">
  <MapUnit.Elements>
    <map:CodeMapPackage Type="Microsoft.Phone.Maps.Controls.Map">
      <map:CodeMapPackage.Maps>

        ...
        <map:CodeMap Kind="Call" MemberName="SetView">
          <map:Conditional>
            <map:Case>
              <map:Case.Condition>
                <map:WithMethodCall>
                  <map:WithCalledMemberOwner>
                    <map:AssignName>$mapInstance</map:AssignName>
                  </map:WithCalledMemberOwner>
                  <map:WithArgument Position="0">
                    <map:AssignName>$arg0</map:AssignName>
                  </map:WithArgument>
                  <map:WithArgument Position="1">
                    <map:AssignName>$arg1</map:AssignName>
                  </map:WithArgument>
                </map:WithMethodCall>
              </map:Case.Condition>
              <map:Case.Action>
                <map:ReplaceWithTemplate>
                  await $mapInstance.TrySetViewAsync($arg0, $arg1)
                </map:ReplaceWithTemplate>
              </map:Case.Action>
            </map:Case>
            ...
          </map:Conditional>
        </map:CodeMap>
        ...
    </map:CodeMapPackage>
</MapUnit.Elements>
</MapUnit>

Given the following code:

--Windows Phone 8 Silverlight--

void SetMapView(Map aMap)
{
    aMap.SetView(coordinate, 0.5);
}

We can apply this mapping and get the following code:

async void SetMapView(Windows.UI.Xaml.Controls.Maps.MapControl aMap)
{
    await aMap.TrySetViewAsync(coordinate, 0.5);
}

The WithCalledMemberOwner code action is used in this case to capture parts of a expression. The following picture shows how the different parts of the expression are captured.

Notes

• This condition succeeds if the current element is of the form a.foo().
