clear

void clear()

Method to clear out any cached schema information.

createDatabase

void createDatabase(String catalogName,
                    String schemaName,
                    Properties props,
                    Object connection)

Method to create the specified database (catalog/schema).

Parameters:

catalogName - Name of the catalog

schemaName - Name of the schema

props - Any properties controlling the schema generation

connection - Connection to use (null implies this will obtain its own connection)

deleteDatabase

void deleteDatabase(String catalogName,
                    String schemaName,
                    Properties props,
                    Object connection)

Method to delete the specified database (catalog/schema).

Parameters:

catalogName - Name of the catalog

schemaName - Name of the schema

props - Any properties controlling the schema deletion

connection - Connection to use (null implies this will obtain its own connection)

createSchemaForClasses

void createSchemaForClasses(Set<String> classNames,
                            Properties props,
                            Object connection)

Method to generate the required schema for the supplied classes. Note that this does not generate a "schema", just the tables. Refer to createDatabase to create a "schema".

Parameters:

classNames - Names of the classes we want the schema generating for.

props - Any properties controlling the schema generation

connection - Connection to use (null implies this will obtain its own connection)

deleteSchemaForClasses

void deleteSchemaForClasses(Set<String> classNames,
                            Properties props,
                            Object connection)

Method to delete the schema for the supplied classes. Note that this does not delete a "schema", just the tables. Refer to deleteDatabase to delete a "schema".

Parameters:

classNames - Names of the classes we want the schema deleting for.

props - Any properties controlling the schema deletion

connection - Connection to use (null implies this will obtain its own connection)

validateSchema

void validateSchema(Set<String> classNames,
                    Properties props,
                    Object connection)

Method to validate the schema for the supplied classes.

Parameters:

classNames - Names of classes

props - Any properties controlling schema validation

connection - Connection to use (null implies this will obtain its own connection)

getSchemaData

StoreSchemaData getSchemaData(Object connection,
                              String name,
                              Object[] values)

Accessor for schema data store under the provided name and defined by the specified values. The supported types of values is particular to the implementation.

Parameters:

connection - Connection to the datastore

name - Name of the schema component to return.

values - Value(s) to use as qualifier(s) for selecting the schema component

Returns:

Schema data definition for this name
