java-reflection

java-reflection is an advanced toolbox for finding compatible methods, constructors, annotations and converting values.

It defines utilities on Class level, Method level, Bean level, Package level, Type level and General utilities.

In additions, it provides an advanced conversion framework, that uses Dijkstra's graph to find the most efficient conversion route, through multiple converters if a direct one is not available. It contains many built in converters and allows for easy extension.

  • The Jakarta Activation framework is now an explicit dependency

v3.10.1 (21-October-2019)

  • Made locateClass a little bit more user friendly by deferring return type T

v3.10.0 (28-September-2019)

  • Added methods for finding parameters by annotations type
  • Moved to Intellij @Nullability annotations
  • Added license boilerplate code in Maven build script

v3.9.3 (10-May-2019)

  • Added API for checking method compatibility based on actual arguments rather than by types only
  • Added helper method to zip method parameters with their respective actual arguments
  • Made the LookupMode arguments of type Set rather than EnumSet, so they can be made unmodifiable
  • Added convenience method for returning the verify and return the only method in a findMethods result

v3.9.2 (30-April-2019)

  • Added API to easily invoke bean setters / getters or methods

v3.9.1 (27-April-2019)

v3.8.1 - v3.8.5 (13-October-2018 - 8-Januari-2019)

  • Added support for same-type converters
  • Performance update: implemented cache for generateComptibleSignatureLists
  • Fixed Incompatible type exception if a number is outside of Byte or Short range
  • Incompatible type exceptions are now gathered in case a conversion ultimately failed

v3.8.0 (9-October-2018)

  • Added File based converters to InputStream, DataSource and byte[]
  • Fixed problem with conversion candidates failing during actual conversions, so now we try all candidates rather than just the first one

  • Fixed name based type matching to properly work with arrays vs varargs...

v3.5.0 (30-September-2018)

  • Made method collection facilities in ClassUtil much more robust by allowing any combination of method modifiers to find methods for rather than just a boolean "publicOnly". This includes modifiers other than for visibility as well.

v3.4.0 (26-September-2018)

  • Added BeanUtils API to verify if a given Method is a bean setter / getter

v3.3.0 (26-September-2018)
