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

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 AbstractCommandStep

parseSchemas

public static CatalogAndSchema[] parseSchemas(Database database,
                                              String... schemas)

getSnapshotMetadata

public Map<String,Object> getSnapshotMetadata()

setSnapshotMetadata

public void setSnapshotMetadata(Map<String,Object> snapshotMetadata)

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.

Throws:

Exception

printSnapshot

public static String printSnapshot(CommandScope commandScope,
                                   CommandResults snapshotResults)
                            throws LiquibaseException

Throws:

LiquibaseException

logUnsupportedDatabase

public static void logUnsupportedDatabase(Database database,
                                          Class callingClass)
