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 AbstractCommandStep

Returns:

list with the required classes types

providedDependencies

public List<Class<?>> providedDependencies()

Description copied from interface: CommandStep

Returns a list of all the dependency Classes that this step provides

Specified by:

providedDependencies in interface CommandStep

Overrides:

providedDependencies in class AbstractCommandStep

Returns:

list with the provided classes types

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

adjustCommandDefinition

Description copied from class: AbstractCommandStep

Default implementation makes no changes

Specified by:

adjustCommandDefinition in interface CommandStep

Overrides:

adjustCommandDefinition in class AbstractCommandStep

run

public void run(CommandResultsBuilder resultsBuilder)
         throws Exception

Description copied from interface: CommandStep

validate

public void validate(CommandScope commandScope)
              throws CommandValidationException

Description copied from class: AbstractCommandStep

Default implementation does no additional validation.

Specified by:

Overrides:

validate in class AbstractCommandStep

Throws:

CommandValidationException
