Method Detail

getFieldHandlersFromFeatureType

protected List<NativeFieldHandler<org.opengis.feature.simple.SimpleFeature,Object>> getFieldHandlersFromFeatureType(org.opengis.feature.simple.SimpleFeatureType type)

Description copied from class: FeatureDataAdapter

Create List of NativeFieldHandlers based on the SimpleFeature type passed as parameter.

Overrides:

getFieldHandlersFromFeatureType in class FeatureDataAdapter

Parameters:

type - - SFT to be used to determine handlers

Returns:

List of NativeFieldHandlers that correspond to attributes in featureType

getReader

public FieldReader<Object> getReader(String fieldName)

Description copied from class: FeatureDataAdapter

Get a reader for an individual field.

Specified by:

getReader in interface DataReader<Object>

Overrides:

getReader in class FeatureDataAdapter

Parameters:

fieldName - the ID of the field

Returns:

Field Reader for the given Field ID

getWriter

public FieldWriter<org.opengis.feature.simple.SimpleFeature,Object> getWriter(String fieldName)

Description copied from class: FeatureDataAdapter

Get a writer for an individual field given the ID.

Specified by:

getWriter in interface DataWriter<org.opengis.feature.simple.SimpleFeature,Object>

Overrides:

getWriter in class FeatureDataAdapter

Parameters:

fieldName - the unique field ID

Returns:

Field Writer for the given Field ID

getPositionOfOrderedField

public int getPositionOfOrderedField(CommonIndexModel model,
                                     String fieldName)

Description copied from interface: DataTypeAdapter

for efficiency we assume fields have some pre-defined ordering. If the field belongs in the common index model it should be one of the first n positions where n is the number of fields in the common index model.

Specified by:

getPositionOfOrderedField in interface DataTypeAdapter<org.opengis.feature.simple.SimpleFeature>

Overrides:

getPositionOfOrderedField in class FeatureDataAdapter

Parameters:

model - the index model

fieldName - the field name

Returns:

the position

getFieldNameForPosition

public String getFieldNameForPosition(CommonIndexModel model,
                                      int position)

Description copied from interface: DataTypeAdapter

Get the field name for the position

Specified by:

getFieldNameForPosition in interface DataTypeAdapter<org.opengis.feature.simple.SimpleFeature>

Overrides:

getFieldNameForPosition in class FeatureDataAdapter

Parameters:

model - the index model

position - the position

Returns:

the field name, if its part of the common index model, it should be the common field name

newBuilder

protected NativeFieldHandler.RowBuilder<org.opengis.feature.simple.SimpleFeature,Object> newBuilder()

Overrides:

newBuilder in class FeatureDataAdapter
