Method Details

addOptions

public void addOptions(joptsimple.OptionParser parser)

Description copied from interface: KVImplementation

Add implementation-specific command line options.

All of the added options must be optional, because multiple key/value implementations will be available when the command line is parsed, and the presence of implementation-specific options determines which one(s) are chosen.

Specified by:

addOptions in interface KVImplementation<SQLiteKVImplementation.Config>

Parameters:

parser - command line flag parser

buildConfig

public SQLiteKVImplementation.Config buildConfig(joptsimple.OptionSet options)

Description copied from interface: KVImplementation

Build a configuration from implementation-specific command line options, if any were given.

If none of this implementation's options were provided, then this method must return null.

Specified by:

buildConfig in interface KVImplementation<SQLiteKVImplementation.Config>

Parameters:

options - parsed command line options

Returns:

corresponding configuration, or null if this implementation was not configured

providesKVDatabase

public boolean providesKVDatabase(SQLiteKVImplementation.Config config)

Description copied from interface: KVImplementation

Determine whether this KVImplementation includes an implementation of the KVDatabase interface.

The implementation in KVImplementation return false.

Specified by:

providesKVDatabase in interface KVImplementation<SQLiteKVImplementation.Config>

Parameters:

config - implementation configuration returned by buildConfig()

Returns:

true if this instance can create an KVDatabase

createKVDatabase

public SQLiteKVDatabase createKVDatabase(SQLiteKVImplementation.Config config,
 KVDatabase kvdb,
 AtomicKVStore kvstore)

Description copied from interface: KVImplementation

Create an KVDatabase using the specified configuration.

The implementation in KVImplementation always throws UnsupportedOperationException.

Specified by:

createKVDatabase in interface KVImplementation<SQLiteKVImplementation.Config>

Parameters:

config - implementation configuration returned by buildConfig()

kvdb - required KVDatabase; will be null unless KVImplementation.requiresKVDatabase(C) returned true

kvstore - required AtomicKVStore; will be null unless KVImplementation.requiresAtomicKVStore(C) returned true

Returns:

new KVDatabase instance

getDescription

public String getDescription(SQLiteKVImplementation.Config config)

Description copied from interface: KVImplementation

Generate a short, human-readable description of the KVDatabase instance configured as given.

Specified by:

getDescription in interface KVImplementation<SQLiteKVImplementation.Config>

Parameters:

config - implementation configuration returned by buildConfig()

Returns:

human-readable description
