Class DynamicSchemaFactory

java.lang.Object
  org.apache.openjpa.jdbc.schema.NameSet
      org.apache.openjpa.jdbc.schema.SchemaGroup
          org.apache.openjpa.jdbc.schema.DynamicSchemaFactory

All Implemented Interfaces:

Cloneable, SchemaFactory, Configurable

public class DynamicSchemaFactory
extends SchemaGroup
implements SchemaFactory, Configurable

Factory whose schema group dynamically fills itself with information as mappings validate themselves in their map method. Tables are added when SchemaGroup.findTable(org.apache.openjpa.jdbc.schema.Table) is called. Columns are added to tables when Table.getColumn(java.lang.String) is called. And the column types are set when Column.isCompatible(int, int) is called.

Overrides:

isKnownTable in class SchemaGroup

findTable

public Table findTable(String name)

Description copied from class: SchemaGroup

Find the table with the given name in the group, using '.' as the catalog separator. Returns null if no table found.
