validate

public ValidationErrors validate(AlterSequenceStatement alterSequenceStatement,
 Database database,
 SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

Validate the data contained in the SqlStatement. If there are no errors, return an empty ValidationErrors object, not a null value. Liquibase will inspect the ValidationErrors result before attempting to call generateSql.
