Method Details

useConnection

public MetaDataImpl useConnection(Connection conn)

Description copied from interface: MetaData

Use the given connection for all database accesses instead of obtaining new ones from the data source.

Specified by:

useConnection in interface MetaData

getDataSourceName

public String getDataSourceName()

Specified by:

getDataSourceName in interface MetaData

getDataSource

public DataSource getDataSource()

Specified by:

getDataSource in interface MetaData

getSchemaName

public String getSchemaName()

Specified by:

getSchemaName in interface MetaData

isDefault

public boolean isDefault()

Specified by:

isDefault in interface MetaData

clearCache

public void clearCache()

Specified by:

clearCache in interface MetaData

getTables

public Iterable<TableMetaData> getTables()

Specified by:

getTables in interface MetaData

getForeignKeyInfo

public Iterable<MetaData.ForeignKeyInfo> getForeignKeyInfo(TableMetaData source,
 TableMetaData target)

Description copied from interface: MetaData

Returns all foreign key information from the source table that references primary or unique keys in the target table.

Most often, this will contain one item or is empty, as there are usually not more than one reference from one table to another.

Specified by:

getForeignKeyInfo in interface MetaData

getForeignKeyInfo

public Iterable<MetaData.ForeignKeyInfo> getForeignKeyInfo(RelationModel model)

Description copied from interface: MetaData

Finds the foreign key information at the database for the given relation model.

If this is a many-to-many relation, there are two foreign key infos returned, where the foreignkey is always the same link table and the primary key either the target or source table of the relation.

If this is a many-to-one relation, there is only one foreign key info returned, where the foreign key is the one-side (source) of the relation and the primary key the many side (target).

Specified by:

getForeignKeyInfo in interface MetaData

forEntity

public Optional<TableMetaData> forEntity(EntityModel model)

Description copied from interface: MetaData

Finds a table corresponding to the given entity model.

Specified by:

forEntity in interface MetaData

forTable

public Optional<TableMetaData> forTable(String tableName)

Description copied from interface: MetaData

Finds a table with the given tablename.

Specified by:

forTable in interface MetaData

forRelation

public Optional<TableMetaData> forRelation(RelationModel relationModel)

Description copied from interface: MetaData

Finds the link table for the given n:m relation model.

Specified by:

forRelation in interface MetaData

findColumns

public Iterable<ColumnMetaData> findColumns(RelationModel relationModel)

Description copied from interface: MetaData

Finds the foreign key columns for the given 1:n relation model.

Specified by:
