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:

Serializable, 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, java.lang.String, int, int) is called.

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.

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

isKnownTable

public boolean isKnownTable(QualifiedDBIdentifier path)

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

findTable

public Table findTable(DBIdentifier name)

findTable

public Table findTable(QualifiedDBIdentifier path)

Overrides:

findTable in class SchemaGroup

newTable

protected Table newTable(DBIdentifier name,
                         Schema schema)

Overrides:

newTable in class SchemaGroup

newColumn

protected Column newColumn(DBIdentifier name,
                           Table table)

Overrides:

newColumn in class SchemaGroup
