DirectiveProcessor.GetPreInitializationCodeForProcessingRun Method

When overridden in a derived class, gets code to add to the start of the initialize method of the generated transformation class.

Namespace:  Microsoft.VisualStudio.TextTemplating
Assembly:  Microsoft.VisualStudio.TextTemplating.11.0 (in Microsoft.VisualStudio.TextTemplating.11.0.dll)

Syntax

'Declaration
Public MustOverride Function GetPreInitializationCodeForProcessingRun As String
public abstract string GetPreInitializationCodeForProcessingRun()
public:
virtual String^ GetPreInitializationCodeForProcessingRun() abstract
abstract GetPreInitializationCodeForProcessingRun : unit -> string
public abstract function GetPreInitializationCodeForProcessingRun() : String

Return Value

Type: String
A String that contains the code to add to the generated transformation class.

Implements

IDirectiveProcessor.GetPreInitializationCodeForProcessingRun()

Remarks

This method adds code to the start of the Initialize method of the generated transformation class. The Initialize method of the generated transformation class contains a call to the Initialize method of the base class, and this code is added before that call. For example, the following pseudo-code shows what the Initialize method of the generated transformation class might resemble:

Method GeneratedTransformationClassInstance.Initialize()

{

<code added by GetPreInitializationCodeForProcessingRun()>

base.Initialize() *This is a call to TextTransformation.Initialize()

<code added by GetPostInitializationCodeForProcessingRun()>

}

Examples

The following code example shows a possible implementation for a custom directive processor. This code example is part of a larger example provided for the DirectiveProcessor class.

public override string GetPreInitializationCodeForProcessingRun()
{
    //We do not need any pre-initialization, so we will just return "".
    //-----------------------------------------------------------------
    return String.Empty;
}
Public Overrides Function GetPreInitializationCodeForProcessingRun() As String

    'We do not need any pre-initialization, so we will just return "".
    '-----------------------------------------------------------------
    Return String.Empty
End Function
