Method Detail

getTableMap

protected java.util.Map<java.lang.String,Table> getTableMap()

Description copied from class: AbstractSchema

Returns a map of tables in this schema by name.

The implementations of AbstractSchema.getTableNames() and AbstractSchema.getTable(String) depend on this map. The default implementation of this method returns the empty map. Override this method to change their behavior.

Overrides:

getTableMap in class AbstractSchema

Returns:

Map of tables in this schema by name
