Interface DatabaseStructure

All Superinterfaces:

ExportableProducer

All Known Implementing Classes:

SequenceStructure, TableStructure

public interface DatabaseStructure
extends ExportableProducer

Encapsulates definition of the underlying data structure backing a sequence-style generator.

Method Summary

Modifier and Type	Method	Description
AccessCallback	buildCallback(SharedSessionContractImplementor session)	A callback to be able to get the next value from the underlying structure as needed.
default void	configure(Optimizer optimizer)	Configures this structure with the given arguments.
default String[]	getAllSqlForTests()	Deprecated. Exposed for tests only.
int	getIncrementSize()	The configured increment size
int	getInitialValue()	The configured initial value
default String	getName()	Deprecated. Use getPhysicalName() instead.
QualifiedName	getPhysicalName()	The physical name of the database structure (table or sequence).
int	getTimesAccessed()	How many times has this structure been accessed through this reference?
default void	initialize(SqlStringGenerationContext context)	Initializes this structure, in particular pre-generates SQL as necessary.
boolean	isPhysicalSequence()	Is the structure physically a sequence?
default void	prepare(Optimizer optimizer)	Deprecated. Use configure(Optimizer) instead.
void	registerExportables(Database database)	Register database objects involved in this structure, e.g.

Method Detail

getName

@Deprecated
default String getName()

Deprecated.

Use getPhysicalName() instead.

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

getPhysicalName

QualifiedName getPhysicalName()

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

Only available after registerExportables(Database) has been called.

Returns:

The structure name.

getTimesAccessed

int getTimesAccessed()

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

Returns:

The number of accesses.

getInitialValue

int getInitialValue()

The configured initial value

Returns:

The configured initial value

getIncrementSize

int getIncrementSize()

The configured increment size

Returns:

The configured increment size

buildCallback

AccessCallback buildCallback(SharedSessionContractImplementor session)

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

Parameters:

session - The session.

Returns:

The next value.

prepare

@Deprecated
default void prepare(Optimizer optimizer)

Deprecated.

Use configure(Optimizer) instead.

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

Parameters:

optimizer - The optimizer being applied to the generator.

configure

default void configure(Optimizer optimizer)

Configures this structure with the given arguments.

Called just after instantiation, before initialize(SqlStringGenerationContext)

Parameters:

optimizer - The optimizer being applied to the generator.

registerExportables

void registerExportables(Database database)

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

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

Specified by:

registerExportables in interface ExportableProducer

Parameters:

database - The database instance

initialize

default void initialize(SqlStringGenerationContext context)

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

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

Parameters:

context - A context to help generate SQL strings

isPhysicalSequence

boolean isPhysicalSequence()

Is the structure physically a sequence?

Returns:

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

getAllSqlForTests

@Deprecated
default String[] getAllSqlForTests()

Deprecated.

Exposed for tests only.
