defineCommandNames

public String[][] defineCommandNames()

Description copied from interface: CommandStep

Defines new command names For example, if it is part of `liquibase update`, this should return new String[][]{ new String[] {"update"}}. If it is a part of `liquibase example init`, this should return {"example", "init"}.

Description copied from class: AbstractCommandStep

Default implementation makes no changes

Specified by:
