Interface HiveRecordInfoProvider

All Known Implementing Classes:

GeoJsonHiveRecordInfoProvider, ShapefileHiveRecordInfoProvider

public interface HiveRecordInfoProvider

An implementation of this interface is used to extract the geometry information from a Hive table's field representing a geometry. The implementer should know how to interpret the record to provide the geometry. The provided geometry has to be in GeoJSON format and contain the geometry SRID like {"type":"geometry-type", "crs": { "type": "name", "properties": {"name": "EPSG:SRID"}}"coordinates":[c1,c2,....cn]}

Method Summary

Modifier and Type	Method and Description
java.lang.String	getGeometry() Gets the geometry of the current record or null if the record does not have spatial information.
void	setCurrentRecord(java.lang.Object record) Sets the record object.

Method Detail

getGeometry

java.lang.String getGeometry()

Gets the geometry of the current record or null if the record does not have spatial information. The provided geometry has to be in GeoJSON format and contain the geometry SRID like {"type":"geometry-type", "crs": { "type": "name", "properties": {"name": "EPSG:SRID"}}"coordinates":[c1,c2,....cn]}

Returns:

the current record's geometry in GeoJSON format or null if the record does not have spatial information..

setCurrentRecord

void setCurrentRecord(java.lang.Object record)
               throws java.lang.Exception

Sets the record object. The record is a Hive table's field representing a geometry.

Parameters:

record - the record is a Hive table's field representing a geometry.

Throws:

java.lang.Exception
