Class ReflectiveVersionMigrationScript<T,E>

java.lang.Object

software.xdev.micromigration.scripts.ReflectiveVersionMigrationScript<T,E>

All Implemented Interfaces:

MigrationScript<T,E>

public abstract class ReflectiveVersionMigrationScript<T,E>
extends java.lang.Object
implements MigrationScript<T,E>

Script which creates the target version of the script through the class name.

Class name has to be in the scheme:
vM_Classname
vM_m_Classname
vM_m_m_Classname
Where v is short for version and is a constant (just a char),
M is a integer for the major version,
m is a integer for the minor version
Classname is a custom String that the user can choose.
This scheme can basically be extended infinetly. For example: v1_1_2_2_MyUpdateScript

Therefore the character _ can only be used as a seperator of versions and may not be used for other purposes.

If the class name has the wrong format, an Error is thrown.
