the reason is spi do not want to use interface to reference JsonIterator and JsonStream. If we make JsonIterator/JsonStream interface, it will make spi bottom of the dependency tree. however, that will rely on hotspot to devirtualize the call, otherwise the penality of virtual method call will slow us down. Logically, there are three dependency group. iterator/output/spi
from java.
But there is more than that, e.g. JsoniterSpi depends on java.lang.reflect.* and logic for different gen modes hardcoded in Codegen.gen() method probably could be moved into extensions, so different modes could use/activate corresponding extensions.
from java.
I will move StringShortDecoder out, it is the only place depending on CodegenAccess, which is not about codgen, but private api of JsonStream.
from java.
@ekuleshov I just moved StringIntDecoder and other concrete decoders into com.jsoniter.fuzzy. Spi should only depend on JsonStream and JsonIterator now. We can use interface to decouple the package, but I choose not to do that, unless we can prove all mainstream jvm (including android) can devirtualize method calls reliably.
from java.
