public DirectGeneric(IContainer parent,
                     java.lang.String type)
```
    Constructor without implicit property.
    
    Parameters:
    
    parent - containing binding definition structure
    
    type - fully qualified class name of object type handled by this binding (null if unspecified)
  - DirectGeneric
```
public DirectGeneric(IContainer parent,
                     java.lang.String type,
                     PropertyDefinition prop)
```
    Constructor with defined property.
    
    Parameters:
    
    parent - containing binding definition structure
    
    type - fully qualified class name of object type handled by this binding (null if unspecified)
    
    prop - associated property information
- Method Detail
  - genTestPresent
```
public void genTestPresent(ContextMethodBuilder mb)
```
    Generate presence test code for this mapping. The generated code just checks that a start tag is next in the document, rather than an end tag.
    
    Parameters:
    
    mb - method builder
  - genUnmarshal
```
public void genUnmarshal(ContextMethodBuilder mb)
                  throws JiBXException
```
    Generate unmarshalling code for this mapping. The generated code just calls the generic unmarshal element method, leaving the unmarshalled object on the stack (after casting it, if necessary, to the appropriate type). TODO: Instead call unmarshalling method with class passed directly, for better error reporting.
    
    Parameters:
    
    mb - method builder
    
    Throws:
    
    JiBXException
  - genMarshal
```
public void genMarshal(ContextMethodBuilder mb)
                throws JiBXException
```
    Generate marshalling code for this mapping. The generated code loads the object reference and casts it to the generic marshal interface, then calls the marshal method of that interface.
    
    Parameters:
    
    mb - method builder
    
    Throws:
    
    JiBXException
  - isOptional

  - genAttrPresentTest
```
public void genAttrPresentTest(ContextMethodBuilder mb)
```
    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
  - genAttributeUnmarshal
```
public void genAttributeUnmarshal(ContextMethodBuilder mb)
```
    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
  - genAttributeMarshal
```
public void genAttributeMarshal(ContextMethodBuilder mb)
```
    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
  - 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
```

                           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
```
    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:

  - 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
    
    Check if component defines an ID value for instances of context object.

    hasId in interface IComponent
    
    Returns:
    
    true if ID value defined for instances, false if not
  - genLoadId
```
public void genLoadId(ContextMethodBuilder mb)
```
    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
  - 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()
```
    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
  - print
```
public void print(int depth)
```
    Specified by:
    
    print in interface IComponent
