public abstract class AbstractArgumentFactory<T>
extends Object
implements ArgumentFactory.Preparable
An
ArgumentFactory
base class for arguments of type T
. For values of type T
, factories
produces arguments from the build(Object, ConfigRegistry)
method. For null values with a known expected type
of T
, produces null arguments for the sqlType
passed to the constructor.
class ValueType { String value; } class ValueTypeArgumentFactory extends AbstractArgumentFactory<ValueType> { ValueTypeArgumentFactory() { super(Types.VARCHAR); } @Override protected Argument build(ValueType valueType, ConfigRegistry config) { return (pos, stmt, ctx) -> stmt.setString(pos, valueType.value); } }Don't forget to override
Object.toString()
in your Argument
instances if you want to be able to log their values with an SqlLogger
