Java-Reflection-Utils

A small library for wrapping some reflection logic

see https://github.com/ricomaster9000/Java-Reflection-Utils/blob/main/src/main/java/org/greatgamesonly/opensource/utils/reflectionutils/ReflectionUtils.java for all the methods one can use

add as dependency by using jitpack.io, go to this link: https://jitpack.io/#ricomaster9000/Java-Reflection-Utils/1.1.15
