PipelineComponent.ReinitializeMetaData Method

Artigo
12/03/2008

Repairs any errors identified during validation that cause the component to return VS_NEEDSNEWMETADATA at design time.

Namespace: Microsoft.SqlServer.Dts.Pipeline
Assembly: Microsoft.SqlServer.PipelineHost (in microsoft.sqlserver.pipelinehost.dll)

Syntax

'Declaration
Public Overridable Sub ReinitializeMetaData

public virtual void ReinitializeMetaData ()

public:
virtual void ReinitializeMetaData ()

public void ReinitializeMetaData ()

public function ReinitializeMetaData ()

Remarks

The ReinitializeMetaData method is called in response to the component returning VSNEEDSNEWMETADATA from Validate. Components should implement code that fixes these errors.

Example

public override DTSValidationStatus Validate()
{
    if (!ComponentMetaData.AreInputColumnsValid)
        return DTSValidationStatus.VS_NEEDSNEWMETADATA;
}
public override void ReinitializeMetaData()
{
    if (!ComponentMetaData.AreInputColumnsValid)
        ComponentMetaData.RemoveInvalidInputColumns();
}

Public Overrides Function Validate() As DTSValidationStatus 
 If Not ComponentMetaData.AreInputColumnsValid Then 
   Return DTSValidationStatus.VS_NEEDSNEWMETADATA 
 End If 
End Function 

Public Overrides Sub ReinitializeMetaData() 
 If Not ComponentMetaData.AreInputColumnsValid Then 
   ComponentMetaData.RemoveInvalidInputColumns 
 End If 
End Sub
