Class provides a generic lookup class to users with a mechanism to cache data retreived from a table. The object containing the data, query retreiving the data and the key for the cache are all configurable propertied read from the component configuration file.

It reads the data from database using the configured query and loads it into Javabean objects which are then stored in cache.

Returns an instance of configured map implementation. This method just returns a new and blank instance. In case comparator is defined for the map, the appropriate constructor of the map implementation is used to create the new instance.

Loads the cache with data elements. Executes the configured SQL query and loads the data into configured bean.

Creates and executes the PreparedStatement to retrieve data from database.

Returns an instance of configured map implementation. This method just returns a new and blank instance. In case comparator is defined for the map, the appropriate constructor of the map implementation is used to create the new instance.

Please note that the new map instance is not synchronized in this method. As required the synchronization takes place in the WritableCache

Loads the cache with data elements. Executes the configured SQL query and loads the data into configured bean.

Reads the configuration to retrieve a map of db columns and bean attributes. Reads the value for each column from database and populates it into the mapping bean attributes.

Creates and executes the PreparedStatement to retrieve data from database. This method abstracts out the creation and execution of SQL statement.

You can extend this class and provide implementation for this method in case you want to retrieve data using callable statement.
