程序包 com.mysql.cj.result

类 DefaultValueFactory<T>

java.lang.Object

com.mysql.cj.result.DefaultValueFactory<T>

类型参数:

T - value type

所有已实现的接口:

ValueFactory<T>

直接已知子类:

AbstractDateTimeValueFactory, AbstractNumericValueFactory, BinaryStreamValueFactory, BooleanValueFactory, ByteValueFactory, DbDocValueFactory

public abstract class DefaultValueFactory<T>
extends Object
implements ValueFactory<T>

The default value factory provides a base class that can be used for value factories that do not support creation from every type. The default value factory will thrown an UnsupportedOperationException for every method and individual methods must be overridden by subclasses.
