Method Detail

getName

@Deprecated
public String getName()

Deprecated.

Description copied from interface: DatabaseStructure

The name of the database structure (table or sequence).

Specified by:

getName in interface DatabaseStructure

getPhysicalName

public QualifiedName getPhysicalName()

Description copied from interface: DatabaseStructure

The physical name of the database structure (table or sequence).

Only available after DatabaseStructure.registerExportables(Database) has been called.

Specified by:

getPhysicalName in interface DatabaseStructure

Returns:

The structure name.

getInitialValue

public int getInitialValue()

Description copied from interface: DatabaseStructure

The configured initial value

Specified by:

getInitialValue in interface DatabaseStructure

Returns:

The configured initial value

getIncrementSize

public int getIncrementSize()

Description copied from interface: DatabaseStructure

The configured increment size

Specified by:

getIncrementSize in interface DatabaseStructure

Returns:

The configured increment size

getTimesAccessed

public int getTimesAccessed()

Description copied from interface: DatabaseStructure

How many times has this structure been accessed through this reference?

Specified by:

getTimesAccessed in interface DatabaseStructure

Returns:

The number of accesses.

getAllSqlForTests

public String[] getAllSqlForTests()

Specified by:

getAllSqlForTests in interface DatabaseStructure

prepare

public void prepare(Optimizer optimizer)

Description copied from interface: DatabaseStructure

Prepare this structure for use. Called sometime after instantiation, but before first use.

Specified by:

prepare in interface DatabaseStructure

Parameters:

optimizer - The optimizer being applied to the generator.

buildCallback

public AccessCallback buildCallback(SharedSessionContractImplementor session)

Description copied from interface: DatabaseStructure

A callback to be able to get the next value from the underlying structure as needed.

Specified by:

buildCallback in interface DatabaseStructure

Parameters:

session - The session.

Returns:

The next value.

isPhysicalSequence

public boolean isPhysicalSequence()

Description copied from interface: DatabaseStructure

Is the structure physically a sequence?

Specified by:

isPhysicalSequence in interface DatabaseStructure

Returns:

true if the actual database structure is a sequence; false otherwise.

registerExportables

public void registerExportables(Database database)

Description copied from interface: DatabaseStructure

Register database objects involved in this structure, e.g. sequences, tables, etc.

This method is called just once, after DatabaseStructure.configure(Optimizer), but before DatabaseStructure.initialize(SqlStringGenerationContext).

Specified by:

registerExportables in interface DatabaseStructure

Specified by:

registerExportables in interface ExportableProducer

Parameters:

database - The database instance

initialize

public void initialize(SqlStringGenerationContext context)

Description copied from interface: DatabaseStructure

Initializes this structure, in particular pre-generates SQL as necessary.

This method is called just once, after DatabaseStructure.registerExportables(Database), before first use.

Specified by:

initialize in interface DatabaseStructure

Parameters:

context - A context to help generate SQL strings
