Member Function Documentation

virtual DtGroup* DtShapeFeatureFile::import ( DtShapeReader *  reader )

virtual

Override from DtShapeFile. Returns 0.

Implements DtShapefile.

virtual bool DtShapeFeatureFile::importFeatures ( DtShapeVectorReader *  reader )

virtual

Reads the feature and associated attributes (if specified in the .map file) for each DtShapeRecord in myList.

Implements DtShapefile.

virtual bool DtShapeFeatureFile::initSpecification ( int &  fccCode, DtSpecification &  spec, DtSpecificationID &  specID, DtFeatureTypes  featureType, int  recordNumber, const DtShapeVectorInitializer::DtShapeAttributeMapContainer &  attributeAliasMap  )

protectedvirtual

Called by import features with a spec that contains a DtFidCode and DtFeatureType.

If the spec is not already contained in myVectorReader's local specification list, it is created according to dfad_sedris_map.txt.

virtual bool DtShapeFeatureFile::createNewSpecification ( const DtFilename &  specificationFilename, int  fccCode, DtSpecification &  spec, DtSpecificationID &  specID, DtFeatureTypes  featureType, bool  warn = true  )

protectedvirtual

virtual void DtShapeFeatureFile::readMappedFeatureAttributes ( DtSpecification &  spec, DtSpecificationID &  specID, int  recordNumber, const DtShapeVectorInitializer::DtShapeAttributeMapContainer &  attributeMap, std::list< DtString > &  fieldNamesRead  )

protectedvirtual

Attempts to add an attribute for each dBASE field specified in the supplied mapping.

Any fields that are read by this function have their name added

virtual bool DtShapeFeatureFile::readSingleFeatureAttribute ( DtSpecification &  spec, int  recordNumber, unsigned int  attributeType, const DtString &  fieldName, const DtString &  attributeName  )

protectedvirtual

virtual void DtShapeFeatureFile::readAllFeatureAttributes ( DtSpecification &  spec, DtSpecificationID &  specID, int  recordNumber, const std::list< DtString > &  fieldsToExclude  )

protectedvirtual

Adds an attribute for every field specified in .dbf file.
