Class RawDataRecordSet

java.lang.Object
  com.bbn.openmap.layer.location.db.RawDataRecordSet

public class RawDataRecordSet
extends java.lang.Object

This class is responsible for retrieving Raw Data from a table in a Database given a key. Users of this class should provide Database connection, Table name, Column name that has the key and column name that has the actual data.

If you are going to use this, there are a couple of properties to set:
prefix.rawDataTableName=table name
prefix.rawDataColumnName=data column name
prefix.rawDataKeyColumnName=data key name

Field Summary

protected java.util.Hashtable	byteCache A hashtable to keep track of the byte arrays, using the key.
protected java.sql.Connection	connection Connection object that will be used to retrieve data
protected java.lang.String	rawDataColumnName Column name in the above table that has Raw Data
static java.lang.String	rawDataColumnNameProperty
protected java.lang.String	rawDataKeyColumnName Column name which has the key to lookup above data
static java.lang.String	rawDataKeyColumnNameProperty
protected java.lang.String	tableName Table name from which data would be retrieved
static java.lang.String	tableNameProperty

Constructor Summary
