All Implemented Interfaces:
IComponent, ILinkable
public class DirectGeneric extends Object implements IComponent
Linkage to generic object with defined marshaller and/or unmarshaller. This provides methods used to generate code for marshalling and unmarshalling objects of types unknown at binding time, so long as they have mappings defined.

      Constructor with defined property.

  • Method Details

    • 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

      public boolean isOptional()
      Description copied from interface: IComponent
      Check if component is an optional item.
      Specified by:
      isOptional in interface IComponent
      Returns:
      true if optional, false if required

    • hasAttribute

      public boolean hasAttribute()
      Description copied from interface: IComponent
      Check if component defines one or more attribute values of the containing element.
      Specified by:
      hasAttribute in interface IComponent
      Returns:
      true if one or more attribute values defined for containing element, false if not

    • 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

      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:
      JiBXException - if error in configuration

    • genContentMarshal

      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.

      Specified by:
      genContentMarshal in interface IComponent
      Parameters:
      mb - method builder
      Throws:
      JiBXException - if error in configuration

    • 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 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.
      Specified by:
      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
