Method Details

requiredDependencies

public List<Class<?>> requiredDependencies()

Description copied from interface: CommandStep

Return a list of configured Classes that this command requires to be passed as a dependency.

requiredDependencies in interface CommandStep

Overrides:

requiredDependencies in class AbstractRollbackCommandStep

Returns:

list with the required classes types

run

public void run(CommandResultsBuilder resultsBuilder)
         throws Exception

Description copied from interface: CommandStep

Performs the business logic. This method should not be called directly. It is called by the overall pipeline logic in the CommandScope.execute() order.

Specified by:

run in interface CommandStep

Overrides:

run in class RollbackCommandStep

Throws:

Exception

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 RollbackCommandStep

adjustCommandDefinition

public void adjustCommandDefinition(CommandDefinition commandDefinition)

Description copied from class: AbstractCommandStep

Default implementation makes no changes

Specified by:

adjustCommandDefinition in interface CommandStep

Overrides:

adjustCommandDefinition in class RollbackCommandStep
