Constructor Detail

JdbcFeatureStore

public JdbcFeatureStore()

Default Constructor.

JdbcFeatureStore

public JdbcFeatureStore(DataSource jdbcDS)

Constructor from DataSource.

Parameters:

jdbcDS - native jdbc datasource

JdbcFeatureStore

public JdbcFeatureStore(DataSource jdbcDS,
                        String xmlConfFile)

Constructor from DataSource.

Parameters:

jdbcDS - native jdbc datasource

Method Detail

createSchema

public void createSchema()

Initialize the target database schema by creating expected structures.

TABLE, INDEX will be created for JDBC, but also COLLECTION and INDEXS for MongoDb, or COLUMN FAMILY for Cassandra. The structures will be created only if they don't exist. In some cases, there is nothing todo (Ehcache, Redis, InMemory), the method won't failed but do nothing (it does not clear the DB)

Specified by:

createSchema in interface FeatureStore

Overrides:

createSchema in class AbstractFeatureStore

enable

public void enable(String uid)

Enable/UP/switch on a FlipPoint.

Parameters:

uid - unique feature identifier

disable

public void disable(String uid)

Create Feature is does not exist and enable it.

exist

public boolean exist(String uid)

Check if Feature Exist.

Returns:

unique feature identifier

read

public Feature read(String uid)

Create Feature is does not exist and enable it.

create

public void create(Feature fp)

Create flipPoint in storage (with roles).

Parameters:

fp - create roles

delete

public void delete(String uid)

Remove fliPoint from store.

grantRoleOnFeature

public void grantRoleOnFeature(String uid,
                               String roleName)

Add a role to a flipPOINT.

removeRoleFromFeature

public void removeRoleFromFeature(String uid,
                                  String roleName)

Remove role to acess flip point

readAll

public Map<String,Feature> readAll()

Access to all features to get information.

Returns:

all features

readAllGroups

public Set<String> readAllGroups()

Return a set of existing groups.

Returns:

set of group in the store
