我们是否应该直接使用ScalaSignature？ [英] Should we use the ScalaSignature directly?

问题描述

该ScalaSignature是一个注释。它包含的元信息。

The ScalaSignature is an annotation. It contains meta informations.

• https://github.com/scala/scala/blob/v2.9.2/src/library/scala/reflect/ScalaSignature.java

和则提供解析器。但斯卡拉-library.jar 不包含解析器。它看起来像秘密API。

And then parser is provided. but scala-library.jar is not contains the parser. It seem like secret API.

• https://github.com/scala/scala/blob/v2.9.2/src/scalap/scala/tools/scalap/scalax/rules/scalasig/ScalaSig.scala

但我用ScalaSignature知道一些库。

But I know a few libraries using ScalaSignature.

• https://github.com/lift/framework/blob/2.4-release/core/json/src/main/scala/net/liftweb/json/ScalaSig.scala


• https://github.com/msgpack/msgpack-scala/blob/version-0.6.6/src/main/scala/org/msgpack/scalautil/ScalaSigUtil.scala


• https://github.com/havocp/beaucatcher/blob/v0.5.0/caseclass/src/main/scala/org/beaucatcher/caseclass/ClassAnalysis.scala

顺便说一句，我无法找到ScalaSignature的正式规范。
我担心ScalaSignature的规格可以由斯卡拉版本的变化而变化。
此外，我觉得有使用ScalaSignature因为规范不存在其他一些风险。

By the way, I could not found formal specification of ScalaSignature. I worry that the specification of ScalaSignature may change by a Scala version change. Also I think there are some other risks using ScalaSignature because specification doesn't exists.

此外，Scala2.10将提供一个新的反射API。
我想用ScalaSignature会下降，当2.10发布的原因。

Further, Scala2.10 will provide a new reflection API. I think the reason for using ScalaSignature will decrease, when 2.10 is released.

因此​​，应在使用ScalaSignature？

Thus, should one use the ScalaSignature?

推荐答案

在斯卡拉2.10反射API提供了对Java反射+斯卡拉签名的正式支持的抽象。如果ScalaSignature格式的变化，反射也会随之改变。

Reflection API in Scala 2.10 provides an officially supported abstraction over Java reflection + Scala signatures. If ScalaSignature format changes, reflection will change accordingly.
