- org.jibx.binding.def.PassThroughComponent
- - org.jibx.binding.def.OptionalStructureWrapper

All Implemented Interfaces:

IComponent, ILinkable
```
public class OptionalStructureWrapper
extends PassThroughComponent
```
Component decorator for optional structure with associated property. This just handles necessary glue code generation for the marshalling operations, where the presence of the structure needs to be tested before actually handling tag generation.

```
    Description copied from interface: IComponent
    
    Generate attribute marshalling code. This is called within the code generation for the marshaller of the class associated with the containing element. It needs to generate the necessary code for handling the marshalling operation, consuming the marshalled object reference from the stack.
    
    Specified by:
    
    genAttributeMarshal in interface IComponent
    
    Overrides:
    
    genAttributeMarshal in class PassThroughComponent
    
    Parameters:
    
    mb - method builder
    
    Throws:
    
    JiBXException - if error in configuration
  - genContentMarshal
```
public void genContentMarshal(ContextMethodBuilder mb)
                       throws JiBXException
