Method Detail

convert

public FeatureType convert(FeatureDefn featureDefn,
                  String defaultGeometryField)
                    throws GeometryTypeNotSupportedException,
                           GeometryTypeNotValidException

Converts FeatureDefn to FeatureType and sets default geometry field to created FeatureType.

Parameters:

featureDefn - OGR definition to be converted

defaultGeometryField - Default geometry field. If it is not founded, this method will take the first geometry field.

Returns:

FeatureType Feature type equivalent

Throws:

GeometryTypeNotSupportedException - If there are problems parsing OGR geometry

GeometryTypeNotValidException - If type of OGR Geometry is not supported

convertFields

public List<FieldDefn> convertFields(FeatureType featureType)

Converts FeatureAttributeDescriptor of FeatureType to FieldDefn

Parameters:

featureType - Fields to be converted

Returns:

FieldDefn list OGR fields

convertField

public FieldDefn convertField(FeatureAttributeDescriptor attDescriptor)

Converts FeatureAttributeDescriptor to FieldDefn

Parameters:

attDescriptor -

Returns:

FieldDefn

convertGeometryFields

public List<GeomFieldDefn> convertGeometryFields(FeatureType featureType,
                                        boolean convertDefaultGeometryColumn)

Converts geometry FeatureAttributeDescriptor of FeatureType to GeomFieldDefn

Parameters:

featureType - Geometry fields to be converted

convertDefaultGeometryColumn - True if default geometry will be converted, otherwise default geometry field won't be converted.

Returns:

GeomFieldDefn list OGR Geometry fields

convertGeomField

public GeomFieldDefn convertGeomField(FeatureAttributeDescriptor attDescriptor)

Converts FeatureAttributeDescriptor to GeomFieldDefn

Parameters:

attDescriptor - Attribute to be converted

Returns:

GeomFieldDefn OGR Geometry field

convert

public FeatureProvider convert(FeatureProvider featureProvider,
                      FeatureType featureType,
                      Feature ogrFeature)

Converts Feature to FeatureProvider. If FeatureProvider is null, it will be instantiated. This method only takes into account the fields of received FeatureType.

Parameters:

featureProvider -

featureType - Type of feature provider

ogrFeature - OGR Feature to be converted

Returns:

FeatureProvider FeatureProvder with OGR Feature values

convert

public Feature convert(FeatureProvider featureProvider)
                throws GeometryOperationNotSupportedException,
                       GeometryOperationException

Converts FeatureProvider to Feature.

Parameters:

featureProvider - Feature provider to be converted

Returns:

Feature OGR Feature with feature provider values.

Throws:

GeometryOperationNotSupportedException - If operation used to convert geometries is not supported

GeometryOperationException - If there are some problems converting geometries

convertToOGRGeomType

public int convertToOGRGeomType(int type)

Convert gvSIG geometry type to OGR geometry type. See ogrConstants.

Parameters:

type - A type of Geometry.TYPES

Returns:

int Equivalent type of ogrConstants

convertToGeomType

public int convertToGeomType(int type)

Convert OGR geometry type to gvSIG geometry type. See Geometry.TYPES.

Parameters:

type - A type of ogrConstants

Returns:

int Equivalent type of Geometry.TYPES

convertToOGRType

public int convertToOGRType(int type)

Convert gvSIG type to OGR type. See ogrConstants.

Parameters:

type - A type of DataTypes

Returns:

convert

public org.gdal.ogr.Feature convert(FeatureDefn layerDefn,
                           org.gdal.ogr.Feature feature)

Convert OGR Feature to another OGR Feature. This method take into account only FeatureDefn fields to create new feature. This method is useful when OGR Layer is copied to new DataSource.

Parameters:

layerDefn - Definition of new feature

feature - OGR feature to be converted

Returns:

Fixed feature
