Enum Class ContentType

java.lang.Object

java.lang.Enum<ContentType>

org.jooq.ContentType

All Implemented Interfaces:

Serializable, Comparable<ContentType>, Constable

@Experimental
public enum ContentType
extends Enum<ContentType>

The File.type().

This type describes the semantics of File.content(). The files contained in Commit.delta() will be processed in the following order:

• SNAPSHOT (replacing all other contents of this Commit as well as previous commits, if migrating from Node.root())
• INCREMENT
• SCRIPT
• SCHEMA

When undoing a migration, the order is:

• SCHEMA
• DECREMENT

Enum Constant Summary

Enum Constants

Enum Constant	Description
DECREMENT	The file contains decrement information.
INCREMENT	The file contains increment information.
SCHEMA	The file contains partial schema information.
SCRIPT	The file contains a script.
SNAPSHOT	A snapshot (or tag?) is a file / set of files that describes the entire schema.

Method Summary

Modifier and Type	Method	Description
static ContentType	valueOf(String name)	Returns the enum constant of this class with the specified name.
static ContentType[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

SCHEMA

public static final ContentType SCHEMA

The file contains partial schema information.

Partial schema information could be CREATE TABLE and similar statements, which are not applied as increments in a Migration, but used to create a diff between two Version using Meta.migrateTo(Meta).

INCREMENT

public static final ContentType INCREMENT

The file contains increment information.

Increments could be ALTER TABLE or UPDATE and similar statements, which are applied as increments in a migration using Meta.apply(Queries).

Within the same Commit, increments are sorted according to their File.path().

DECREMENT

public static final ContentType DECREMENT

The file contains decrement information.

Decrements work like INCREMENT typed files, but are applied only when downgrading to a previous version, decrements are sorted in reverse order according to their File.path().

This API is part of a commercial only feature. To use this feature, please use the jOOQ Professional Edition or the jOOQ Enterprise Edition.

SCRIPT

public static final ContentType SCRIPT

The file contains a script.

Scripts are increments that are not processed by jOOQ, and can thus not be interpreted. They can contain vendor-specific SQL that jOOQ doesn't understand.

SNAPSHOT

public static final ContentType SNAPSHOT

A snapshot (or tag?) is a file / set of files that describes the entire schema.

In order to restore a database, or install a new one, we don't have to go back any further than the snapshot.

Method Details

values

public static ContentType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ContentType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
