Method Detail

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"}.

This is used to determine the available command names.

This can return null if this step is not defining a new command but "cross-cutting" existing commands.

Specified by:

defineCommandNames in interface CommandStep

Overrides:

defineCommandNames in class InternalDiffCommandStep

adjustCommandDefinition

public void adjustCommandDefinition(CommandDefinition commandDefinition)

Description copied from class: AbstractCommandStep

Default implementation makes no changes

Specified by:

run

public void run(CommandResultsBuilder resultsBuilder)
         throws Exception

Description copied from interface: CommandStep
