示例1: computeReturnConversion
import sun.invoke.util.ValueConversions; //导入方法依赖的package包/类
/**
* Caller will be expecting a result from a call to {@code type},
* while the internal adapter entry point is rawEntryType.
* Also, the internal target method will be returning a boxed value,
* as an untyped object.
* <p>
* Produce a value converter which will be typed to convert from
* {@code Object} to the return value of {@code rawEntryType}, and will
* in fact ensure that the value is compatible with the return type of
* {@code type}.
