    • getValue

      public Object getValue()
      Description copied from interface: Property
      The value or content of the property.

      The class of this object is defined by getType().getBinding().

      This value may be null. In this case getDescriptor().isNillable() would be true.

      Specified by:
      getValue in interface Property
      Returns:
      The value of the property.

    • setValue

      public void setValue(Object value)
      Description copied from interface: Property
      Sets the value or content of the property.

      The class of newValue should be the same as or a subclass of getType().getBinding().

      newValue may be null if getDescriptor().isNillable() is true.

      Specified by:
      setValue in interface Property
      Parameters:
      value - The new value of the property.

    • getDescriptor

      public PropertyDescriptor getDescriptor()
      Description copied from interface: Property
      The PropertyDscriptor of the property, null if this is a top-level value.

      The descriptor provides information about the property with respect to its containing entity (more often then not a Feature or ComplexAttribute.

      Specified by:
      getDescriptor in interface Property
      Returns:
      The property descriptor, null if this is a top-level value.

      Returns:
      The property type.

      public Map<Object,Object> getUserData()

      A map of "user data" which enables applications to store "application-specific" information against a property.

      An example of information that may wish to be stored along with an attribute could be its srs information (in the case of a geometric attribute ). 

       
  GeometryAttribute attribute = ...;

  //set the crs
  CoordinateReferenceSystem crs = CRS.decode("EPSG:4326");
  attribute.setCRS( crs );

  //set the srs
  attribute.getUserData().put( "srs", "EPSG:4326" );
      Specified by:
      getUserData in interface Property
      Returns:
      A map of user data.
