## org.apache.openjpa.jdbc.schema
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.

Method Detail

### setConfiguration

    public void setConfiguration(Configuration conf)

  Description copied from interface: `Configurable`
  Invoked prior to setting bean properties.

  Specified by:
    `setConfiguration` in interface `Configurable`

### startConfiguration

    public void startConfiguration()

  Description copied from interface: `Configurable`
  Invoked before bean property configuration is begun on this object.

  Specified by:
    `startConfiguration` in interface `Configurable`

### endConfiguration

    public void endConfiguration()

  Description copied from interface: `Configurable`
  Invoked upon completion of bean property configuration for this object.

  Specified by:
    `endConfiguration` in interface `Configurable`

### readSchema

    public SchemaGroup readSchema()

  Description copied from interface: `SchemaFactory`
  Return the schema group for the current object model and database.

  Specified by:
    `readSchema` in interface `SchemaFactory`

### storeSchema

    public void storeSchema(SchemaGroup schema)

  Description copied from interface: `SchemaFactory`
  Record the schema group after changes may have been made.

  Specified by:
    `storeSchema` in interface `SchemaFactory`
  Parameters:
    `schema` - the schema definition for the entire system

### isKnownTable

    public boolean isKnownTable(Table table)

  Description copied from class: `SchemaGroup`
  Return true if the given table is known to exist. While `SchemaGroup.findTable(org.apache.openjpa.jdbc.schema.Table)` may exhibit dynamic behavior in some schema group implementations, this method only returns true if the table has been added to this group or is known to exist in the database.

  Overrides:
    `isKnownTable` in class `SchemaGroup`

### isKnownTable

    public boolean isKnownTable(String name)

  Description copied from class: `SchemaGroup`
  Return true if the given table is known to exist. While `SchemaGroup.findTable(org.apache.openjpa.jdbc.schema.Table)` may exhibit dynamic behavior in some schema group implementations, this method only returns true if the table has been added to this group or is known to exist in the database.

  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.

  Overrides:
    `findTable` in class `SchemaGroup`

### newTable

    protected Table newTable(String name,
                             Schema schema)

  Description copied from class: `SchemaGroup`
  Return a new table with the given name and owner schema.

  Overrides:
    `newTable` in class `SchemaGroup`

### newColumn

    protected Column newColumn(String name,
                               Table table)

  Description copied from class: `SchemaGroup`
  Return a new column with the given name and owner table.
