DeserializeObjectError Event

Summary

Represents the event to trigger when an error occurs during loading an annotation object.

Syntax

C++/CLI

Java

Python

public event EventHandler<AnnSerializeObjectEventArgs> DeserializeObjectError

public void addDeserializeObjectErrorListener(AnnSerializeObjectListener listener) 
public void removeDeserializeObjectErrorListener(AnnSerializeObjectListener listener)

public:  
   event EventHandler<AnnSerializeObjectEventArgs^>^ DeserializeObjectError

def DeserializeObjectError(sender,e): # sender: AnnDeserializeOptions e: AnnSerializeObjectEventArgs

Event Data

The event handler receives an argument of type AnnSerializeObjectEventArgs containing data related to this event. The following AnnSerializeObjectEventArgs properties provide information specific to this event.

Property	Description
AnnObject	The annotation object being loaded or saved.

Remarks

AnnSerializeObjectEventArgs This event will trigger once for each annotation object being loaded with the AnnSerializeObjectEventArgs event data members containing the following:

Member	Description
AnnSerializeObjectEventArgs.Error	The error that occurred.
AnnSerializeObjectEventArgs.TypeName	The type name of the AnnObject being loaded.
AnnSerializeObjectEventArgs.AnnObject	The AnnObject being loaded.
AnnSerializeObjectEventArgs.SkipObject	Set to false. You can change this value to true to skip loading this object and continue to the next.
