      org.placelab.mapper.TempMapper

All Implemented Interfaces:

Mapper

public class TempMapper

extends AbstractMapper

This mapper resides purely in memory, so it is NOT persistent. Use this for debugging.

Method Detail

query

public java.util.Enumeration query(Coordinate c1,
                                   Coordinate c2)

Description copied from interface: Mapper

c1 and c2 define opposing corners of a rectangular area in which you wish to get an Iterator over all Beacons in that area.

Specified by:

query in interface Mapper

Specified by:

query in class AbstractMapper

findBeaconsImpl

protected java.util.Vector findBeaconsImpl(java.lang.String id)

Specified by:

findBeaconsImpl in class AbstractMapper

putBeaconsImpl

protected boolean putBeaconsImpl(java.lang.String id,
                                 java.util.Vector beacons)

Specified by:

putBeaconsImpl in class AbstractMapper

open

public boolean open()

Description copied from interface: Mapper

Opens the Mapper. You must call this method before querying the mapper.

Returns:

whether or not the Mapper was successfully opened.

close

public boolean close()

Description copied from interface: Mapper

Closes the Mapper. Closed Mappers can no longer be queried.

Returns:

whether or not the Mapper was successfully closed.

deleteAll

public boolean deleteAll()

Description copied from interface: Mapper

Deletes all Beacon records in the Mapper. This is typically used by MapLoaders prior to reloading the Mapper with data.

Returns:

whether or not the Mapper was successfully emptied.

isOpened

public boolean isOpened()

startBulkPuts

public void startBulkPuts()

Description copied from interface: Mapper

Signals to the Mapper that it is about to be loaded in bulk. Some implementations can use this to lock their underlying database and speed up loading. You should not query the Mapper while using bulk loading.
