                                                    throws IOException

Add the attributes, types and classifications for the SimpleFeatureType to the provided FeatureDefinition

Parameters:

fd - - existing Feature Definition (or new one if null)

sft - - SimpleFeatureType of the simpleFeature being serialized

defaultClassifications - - map of attribute names to classification

defaultClassification - - default classification if one could not be found in the map

Returns:

the feature definition

Throws:

IOException

Create an AttributeValue from the SimpleFeature's attributes

Parameters:

sf -

sft -

Returns:

the attribute value
