Constructor Detail

### PersistentTagsHandler

    public PersistentTagsHandler()

Method Detail

### isPersistentField

    public static boolean isPersistentField(xjavadoc.XMethod method)

  Returns true if method is a persistent field, false otherwise. Persistent fields are getter methods marked with a ejb:persistent-field tag.

  Parameters:
    `method` - Description of Parameter
  Returns:
    The PersistentField value

### isValueObjectField

    public static boolean isValueObjectField(xjavadoc.XClass clazz,
                                             xjavadoc.XMethod method,
                                             String valueObject)
                                      throws XDocletException

  Gets the ValueObjectField attribute of the PersistentTagsHandler class

  Parameters:
    `clazz` - Describe what the parameter does
    `method` - Describe what the parameter does
    `valueObject` - Describe what the parameter does
  Returns:
    The ValueObjectField value
  Throws:
    `XDocletException`

### isPkField

    public static boolean isPkField(xjavadoc.XMethod method)

  Returns true if method is a primary key field, false otherwise. PK fields are getter methods marked with a ejb:pk-field tag.

  Parameters:
    `method` - Description of Parameter
  Returns:
    The PkField value

### isPkFieldInHeader

    public static boolean isPkFieldInHeader(xjavadoc.XClass clazz)

  Returns true if clazz has ejb:pk-field defined.

  Parameters:
    `clazz` - Description of Parameter
  Returns:
    The PkFieldInHeader value

### fieldList

    public static String fieldList(xjavadoc.XClass clazz,
                                   String inclTag,
                                   String exclTag,

                                   String valueObject,
                                   boolean superclasses)
                            throws XDocletException

  Returns comma-separated list of fields, excluding fields that have tags of exclTag list, including fields that have tags of inclTag list. If name_value_out is true, then the list is in fieldname="value" format.

  Parameters:
    `inclTag` - Fields that have at least of the tags of this comma-separated list are used.
    `exclTag` - Fields that don't have all of the tags of this comma-separated list are used.
    `type` - Type of return (0: comma separated list - 1: field=value comma separated list - 2: getter comma sperated list, 3: comma separated name list)
    `clazz` - Description of Parameter
    `valueObject` -
    `superclasses` -
  Returns:
    Description of the Returned Value
  Throws:
    `XDocletException`
  To do:
    This method only takes the field of the current class. I think it's ok. Any objection ?
