Method Detail

• public static boolean checkAccessible(Class<?> callerClass, Class<?> declaringClass, int memberModifiers, boolean allowIllegalAccess)

• public static boolean checkCanSetAccessible(AccessibleObject accessibleObject, Class<?> caller)

• public static Class getCallingClass()

  Gets the immediate calling class, ignoring MOP frames.

  Returns:

  The Class of the caller

• 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

• 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

• public static Constructor<?>[] getDeclaredConstructorsSorted(Class<?> type)

  Returns the declared constructors of a class in a deterministic order.

  Class.getDeclaredConstructors does not guarantee an order, and a nondeterministic order can flow into generated bytecode; see getDeclaredMethodsSorted(Class).

  Parameters:

  type - the class to introspect

  Returns:

  the declared constructors, sorted by parameter types

  Since:

  5.0.8

• public static List<Method> getDeclaredMethods(Class<?> type, String name, Class<?> parameterTypes)

• public static Method[] getDeclaredMethodsSorted(Class<?> type)

  Returns the declared methods of a class in a deterministic order.

  Class.getDeclaredMethods does not guarantee an order, and HotSpot's varies between JVM runs. When members of a precompiled class are enumerated at compile time (annotation members copied to generated code, trait methods woven into implementing classes, MOP super$ bridge methods, etc.), that order flows into the generated bytecode, so a nondeterministic order produces byte-different class files from identical sources. Callers whose output depends on member order should use this variant so builds are reproducible.

  Parameters:

  type - the class to introspect

  Returns:

  the declared methods, sorted by name then signature

  Since:

  5.0.8

• public static List<Method> getMethods(Class<?> type, String name, Class<?> parameterTypes)

• public static Class<?>[] getPermittedSubclasses(Class<?> clazz)

• 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.
