SerializeObject Event

Summary

Event that triggers when an annotation object is being saved.

Syntax

Objective-C

C++/CLI

Java

Python

public event EventHandler<AnnSerializeObjectEventArgs> SerializeObject

@property (nonatomic,assign) id<LTAnnSerializeObjectDelegate> delegate;

public void addSerializeObjectListener(AnnSerializeObjectListener listener) 
public void removeSerializeObjectListener(AnnSerializeObjectListener listener)

public:  
   event EventHandler<AnnSerializeObjectEventArgs^>^ SerializeObject

def SerializeObject(sender,e): # sender: AnnSerializeOptions 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	Gets or sets the annotation object being loaded or saved.

Remarks

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

Member	Description
TypeName	The type name of the AnnObject being saved.
AnnObject	The AnnObject being saved.
SkipObject	Set to false. You can change this value to true to skip saving this object and continue to the next.

Example
