unwrap

public <X> X unwrap(Long value,

                    WrapperOptions options)

从接口复制的说明: JavaTypeDescriptor

Unwrap an instance of our handled Java type into the requested type.

As an example, if this is a JavaTypeDescriptor<Integer> and we are asked to unwrap the Integer value as a Long we would return something like Long.valueOf( value.longValue() ).

Intended use is during PreparedStatement binding.

类型参数:

X - The conversion type.

参数:

value - The value to unwrap

type - The type as which to unwrap

options - The options

返回:

The unwrapped value.

wrap

public <X> Long wrap(X value,
                     WrapperOptions options)

从接口复制的说明: JavaTypeDescriptor

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

类型参数:

X - The conversion type.

参数:

value - The value to wrap.

options - The options

返回:

The wrapped value.
