Class ReflectionUtils

    • isCallingClassReflectionAvailable

      public static boolean isCallingClassReflectionAvailable()
      Determines whether the getCallingClass methods will return any sensible results. On JVMs that are not Sun derived i.e. (gcj, Harmony) this will likely return false. When not available all getCallingClass methods will return null.
      Returns:
      true if getCallingClass can return anything but null, false if it will only return null.

    • getCallingClass

      public static Class getCallingClass()
      Gets the immediate calling class, ignoring MOP frames.
      Returns:
      The Class of the caller

    • getCallingClass

      public static Class getCallingClass(int matchLevel)
      Gets the called that is matchLevel stack frames before the call, ignoring MOP frames.
      Parameters:
      matchLevel - how may call stacks down to look. If it is less than 1 it is treated as though it was 1.
      Returns:
      The Class of the matched caller, or null if there aren't enough stackframes to satisfy matchLevel

    • getCallingClass

      public static Class getCallingClass(int matchLevel, Collection<String> extraIgnoredPackages)
      Gets the called that is matchLevel stack frames before the call, ignoring MOP frames and desired exclude packages.
      Parameters:
      matchLevel - how may call stacks down to look. If it is less than 1 it is treated as though it was 1.
      extraIgnoredPackages - A collection of string names of packages to exclude in addition to the MOP packages when counting stack frames.
      Returns:
      The Class of the matched caller, or null if there aren't enough stackframes to satisfy matchLevel
