  • Field Details

  • Method Details

    • getConstructorArgumentIndex

      int getConstructorArgumentIndex()
      Returns the index within the constructor argument array where the value of this field should be. A value less than zero indicates that the value of this field is set via a normal setter method and not via the constructor.

      Note: This only applies to attribute mapped fields at this time.

      Returns:
      the index within the constructor argument array for this field.
      See Also:
    • isConstructorArgument

      boolean isConstructorArgument()
      Returns true if the value of the field represented by this descriptor should be set via the constructor of the containing class. This is only valid for attribute mapped fields.
      Returns:
      true if the value of the field represented by this descriptor should be set via the constructor of the containing class.
    • getLocationPath

      String getLocationPath()
      Returns the "relative" XML path for the field being described.

      In most cases, this will be null. However sometimes a field may be mapped to a nested element. In which case the value returned by this method should be the nested element name. If more than one level of nesting is needed each nested element name should be separated by by a path separator (forward slash '/').

      The location path name is "relative" to the parent Class. The name of the parent must not be included in the path.

      For example, give the following two classes:

          class Root {
              Bar bar;
          }
      
          class Bar {
             String value;
          }
       
      And the following XML:
          <root>
             <foo>
                <bar> value of bar </bar>
             </foo>
          </root>
       
      Since <foo> has no associated class, the path for 'bar' would be: "foo"
      Returns:
      The "relative" XML path for the field being described.
    • getNameSpacePrefix

      String getNameSpacePrefix()
      Return the "suggested" namespace prefix to use when marshaling as XML.
      Returns:
      the "suggested" namespace prefix.
    • getNameSpaceURI

      String getNameSpaceURI()
      Returns the namespace URI to be used when marshaling and unmarshaling as XML.
      Returns:
      the namespace URI.
    • getNodeType

      NodeType getNodeType()
      Returns the node type of the field being described. The NodeType represents the type of node that the field will be marshaled into XML as.
      Returns:
      the NodeType of the Field being described.
    • getXMLProperty

      String getXMLProperty(String propertyName)
      Returns the value property with the given name or null if no such property exists. This method is useful for future evolutions of this interface as well as for user-defined extensions. See class declared properties for built-in properties.
      Parameters:
      propertyName - the name of the property whose value should be returned.
      Returns:
      the value of the property, or null.
    • getSchemaType

      String getSchemaType()
      Returns the XML Schema type of the XML field being described.
      Returns:
      the XML Schema type of the XML field being described.
    • getValidator

      FieldValidator getValidator()
      Returns a specific validator for the field described by this descriptor. A null value may be returned if no specific validator exists.
      Returns:
      the field validator for the described field
    • getXMLName

      String getXMLName()
      Returns the XML Name for the field being described.
      Returns:
      the XML name.
    • isContainer

      boolean isContainer()
      Returns true if the field described by this descriptor is a container field. A container is a field that is not a first-class object, and should therefore have no XML representation.
      Returns:
      true if the field is a container
    • isIncremental

      boolean isIncremental()
      Returns the incremental flag which when true indicates that this member may be safely added before the unmarshaler is finished unmarshaling it.
      Returns:
      true if the Object can safely be added before the unmarshaler is finished unmarshaling the Object.
    • isMapped

      boolean isMapped()
      Returns true if the field described by this descriptor is Map or Hashtable. If this method returns true, it must also return true for any call to isMultivalued().
      Returns:
      true if the field described by this desciptor is a Map or Hashtable, otherwise false.
    • isMultivalued

      boolean isMultivalued()
      Returns true if the field described by this descriptor can contain more than one value.
      Specified by:
      isMultivalued in interface FieldDescriptor
      Returns:
      true if the field described by this descriptor can contain more than one value
    • isNillable

      boolean isNillable()
      Returns true if the field described by this descriptor may be nillable. A nillable field is one that may have empty content and still be valid. Please see the XML Schema 1.0 Recommendation for more information on nillable.
      Returns:
      true if the field may be nillable.
    • isReference

      boolean isReference()
      Returns true if the field described by this descriptor is a reference (ie. IDREF) to another object in the "Object Model" (e.g., XML tree).
      Returns:
      true if the field described by this descriptor is a reference to another object in the "Object Model"
    • matches

      boolean matches(String xmlName)
      Returns true if this descriptor can be used to handle elements or attributes with the given XML name. By default this method simply compares the given XML name with the internal XML name. This method can be overridden to provide more complex matching.
      Parameters:
      xmlName - the XML name to compare
      Returns:
      true if this descriptor can be used to handle elements or attributes with the given XML name.
    • matches

      boolean matches(String xmlName, String namespace)
      Returns true if this descriptor can be used to handle elements or attributes with the given XML name. By default this method simply compares the given XML name with the internal XML name. This method can be overridden to provide more complex matching.
      Parameters:
      xmlName - the XML name to compare
      namespace - the namespace URI
      Returns:
      true if this descriptor can be used to handle elements or attributes with the given XML name.
    • getSubstitutes

      List<String> getSubstitutes()
      Returns the possible substitution groups for this class.
      Returns:
      the possible substitution groups for this class.
    • setSubstitutes

      void setSubstitutes(List<String> substitutes)
      Sets the possible substitution groups for this class.
      Parameters:
      substitutes - Possible substitution groups for this class.
    • setDerivedFromXSList

      void setDerivedFromXSList(boolean derivedFromXSList)
      Sets whether the field described by this XMLFieldDescriptorImpl is created as a result of a invalid input: '<'xs:list> definition.
      Parameters:
      derivedFromXSList - A boolean value, true or false.
    • isDerivedFromXSList

      boolean isDerivedFromXSList()
      Indicates whether the field described by this XMLFieldDescriptorImpl is created as a result of a invalid input: '<'xs:list> definition.
      Parameters:
      derivedFromXSList - Trueif the field described by this XMLFieldDescriptorImpl is created as a result of a invalid input: '<'xs:list> definition. .
