CurrencySQLLoader

public CurrencySQLLoader()

Method Detail

changed

public void changed(Currency changedRecord)

Description copied from interface: RecordLoader

accept a notification from a record that it has been changed.

Specified by:

changed in interface RecordLoader<Currency>

Parameters:

changedRecord - the record that has been changed

See Also:

RecordLoader.changed(org.starhope.appius.util.DataRecord)

from

protected Currency from(ResultSet resultSet)
                 throws DataException,
                        SQLException

WRITEME: Document this method brpocock@star-hope.org

Parameters:

resultSet - WRITEME

Returns:

WRITEME

Throws:

SQLException - WRITEME

DataException - WRITEME

getSubversionRevision

public String getSubversionRevision()

Description copied from interface: HasSubversionRevision

Return the Subversion revision level of this class's source code file, as supplied via the special "$Rev: " sequence.

As an example,the Subversion revision string for this file is "$Rev: 1968 $"

 
 @Override
 public String getSubversionRevision () {
        return "$Rev: ";
 }
 

Specified by:

getSubversionRevision in interface HasSubversionRevision

Returns:

The Subversion revision level for this class's source code file.

See Also:

HasSubversionRevision.getSubversionRevision()

initializeStorage

public void initializeStorage(String storageURL)
                       throws NotReadyException

Description copied from interface: RecordLoader

Prepare the RecordLoader for accessing a given storage medium. Usually identifies a URL for the storage mechanism, but can also pull information from AppiusConfig.

Specified by:

initializeStorage in interface RecordLoader<Currency>

Parameters:

storageURL - A URL or identifier of the storage engine. The syntax is specific to the RecordLoader implementation.

Throws:

NotReadyException - if the storage engine can't be initialised

See Also:

RecordLoader.initializeStorage(java.lang.String)

isRealtime

public boolean isRealtime()

Specified by:

isRealtime in interface RecordLoader<Currency>

Returns:

true, if this is a type that requires realtime performance on changes. Note that I/O bound storage such as SQL database saves and file writes will generally return false, whereas RPC mirroring will probably want to return true, unless latency is not an issue.

See Also:

RecordLoader.isRealtime()

loadRecord

public Currency loadRecord(int id)
                    throws NotFoundException

Description copied from interface: RecordLoader

Load the record with the given ID number from the storage system

Specified by:

loadRecord in interface RecordLoader<Currency>

Parameters:

id - the ID number for the record

Returns:

the data record in question

Throws:

NotFoundException - if the record can't be loaded

See Also:

RecordLoader.loadRecord(int)

loadRecord

public Currency loadRecord(String id)
                    throws NotFoundException

Description copied from interface: RecordLoader

Load the data record identified from the storage system. The format and interpretation of the identifier is specific to the data record type, but must be a guaranteed-unique

Specified by:

loadRecord in interface RecordLoader<Currency>

Parameters:

id - database ID

Returns:

currency with that database ID

Throws:

NotFoundException - if it's not found in the database

RuntimeException - if something else wonky were to happen

removeRecord

public void removeRecord(Currency record)

Specified by:

removeRecord in interface RecordLoader<Currency>

Parameters:

record - Record to be deleted/removed

See Also:

RecordLoader.removeRecord(org.starhope.appius.util.DataRecord)

saveRecord

public void saveRecord(Currency record)

Description copied from interface: RecordLoader

Save a record back to the storage system

Specified by:

saveRecord in interface RecordLoader<Currency>

Parameters:

record - the record to be saved

See Also:

RecordLoader.saveRecord(org.starhope.appius.util.DataRecord)

refresh

public void refresh(Currency record)

Description copied from interface: RecordLoader

Refreshes the record: Re-read the contents of the database into the given record. This is a rather cruel hack to work around some of the legacy tools in Tootsville™ that aren't hooked into the game server properly, and might be fiddling around with the SQL backing-store directly. This works together with e.g. SimpleDataRecord.checkStale() to try to reload data when it might have been changed: it's trading elegance and efficiency for expediency, but eventually, it should be removed.

Specified by:

refresh in interface RecordLoader<Currency>

Parameters:

record - the record to be reloaded.
