validate

public ValidationErrors validate(AddDefaultValueStatement statement,
 Database database,
 SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

validate in interface SqlGenerator<AddDefaultValueStatement>

Overrides:

validate in class AddDefaultValueGenerator

getPriority

public int getPriority()

Description copied from interface: SqlGenerator

Of all the SqlGenerators that "support" a given SqlStatement/Database, SqlGeneratorFactory will return the one with the highest priority.
