                        throws JiBXException
```
    Description copied from interface: IComponent
    
    Generate code to test for attribute present. This generates code that tests if a child is present as determined by attributes of the containing start tag. It leaves the result of the test (zero if missing, nonzero if present) on the stack. This call is only valid if this component has one or more attributes for the containing element.
    
    Specified by:
    
    genAttrPresentTest in interface IComponent
    
    Parameters:
    mb - method builder
    
    Throws:
    
    JiBXException - if configuration error
  - genAttributeUnmarshal
```
public void genAttributeUnmarshal(ContextMethodBuilder mb)
                           throws JiBXException
```
    Description copied from interface: IComponent
    
    Generate attribute unmarshalling code. This is called within the code generation for the unmarshaller of the class associated with the containing element. It needs to generate the necessary code for handling the unmarshalling operation, leaving the unmarshalled object reference on the stack.
    
    Specified by:
    
    genAttributeUnmarshal in interface IComponent
    
    Parameters:
    mb - method builder
    
    Throws:
    
    JiBXException - if error in configuration
  - genAttributeMarshal
```
public void genAttributeMarshal(ContextMethodBuilder mb)
                         throws JiBXException
```
    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
    
    Parameters:
    mb - method builder
    
    Throws:
    
    JiBXException - if error in configuration
  - hasContent
```
public boolean hasContent()
```
    Description copied from interface: IComponent
    
    Check if component defines one or more elements or text values as children of the containing element. This method is only valid after the call to ILinkable.setLinkages().
    
    Specified by:
    
    hasContent in interface IComponent
    
    Returns:
    true if one or more content values defined for containing element, false if not
  - genContentPresentTest
```
public void genContentPresentTest(ContextMethodBuilder mb)
                           throws JiBXException
```
    Description copied from interface: IComponent
    
    Generate code to test for content present. This generates code that tests if a required element is present, leaving the result of the test (zero if missing, nonzero if present) on the stack. This call is only valid if this component has one or more content components for the containing element.
    
    Specified by:
    
    genContentPresentTest in interface IComponent
    
    Parameters:
    mb - method builder
    
    Throws:
    
    JiBXException - if configuration error
  - genContentUnmarshal
```
public void genContentUnmarshal(ContextMethodBuilder mb)
                         throws JiBXException
```
    Description copied from interface: IComponent
    
    Generate element or text unmarshalling code. This is called within the code generation for the unmarshaller of the class associated with the containing element. It needs to generate the necessary code for handling the unmarshalling operation, leaving the unmarshalled object reference on the stack.
    
    Specified by:
    
    genContentUnmarshal in interface IComponent
    
    Parameters:
    mb - method builder
    
    Throws:

```
public void genContentMarshal(ContextMethodBuilder mb)
                       throws JiBXException
```
    Description copied from interface: IComponent
    
    Generate element or text 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:
    
    genContentMarshal in interface IComponent
    
    Parameters:
    mb - method builder

  - genNewInstance
```
public void genNewInstance(ContextMethodBuilder mb)
```
    Description copied from interface: IComponent
    
    Generate code to create new instance of object. This is called within the code generation for the unmarshaller of the class associated with the containing element. It needs to generate the necessary code for creating an instance of the object to be unmarshalled, leaving the object reference on the stack.
    
    Specified by:
    
    genNewInstance in interface IComponent
    
    Parameters:
    mb - method builder
  - getType
```
public java.lang.String getType()
```
    Description copied from interface: IComponent
    
    Get type expected by component.
    
    Specified by:
    
    getType in interface IComponent
    
    Returns:
    fully qualified class name of expected type
  - hasId
```
public boolean hasId()
```
    Description copied from interface: IComponent

    hasId in interface IComponent
    
    Returns:
    true if ID value defined for instances, false if not
  - genLoadId
```
public void genLoadId(ContextMethodBuilder mb)
               throws JiBXException
```
    Description copied from interface: IComponent
    
    Generate code to load ID value of instance to stack. The generated code should assume that the top of the stack is the reference for the containing object. It must consume this and leave the actual ID value on the stack (as a String).
    
    Specified by:
    
    genLoadId in interface IComponent
    
    Parameters:
    mb - method builder
    
    Throws:
    
    JiBXException - if configuration error
  - getWrapperName
```
public NameDefinition getWrapperName()
```
    Description copied from interface: IComponent
    
    Get element wrapper name. If the component defines an element as the container for content, this returns the name information for that element.
    
    Specified by:
    
    getWrapperName in interface IComponent
    
    Returns:
    component element name, null if no wrapper element
  - setLinkages
```
public void setLinkages()
                 throws JiBXException
```
    Description copied from interface: ILinkable
    
    Establish and validate linkages between binding components. This is called after the basic binding structures have been set up. All linkages between components must be resolved by this method, in order to prevent problems due to the order of definitions between components. This implies that each component must in turn call the same method for each child component. None of the other method calls defined by this interface are valid until after this call.
    
    Specified by:
    
    setLinkages in interface ILinkable
    
    Throws:
    
    JiBXException - if error in configuration
  - print
```
public void print(int depth)
```
    Specified by:
    
    print in interface IComponent
