Method Detail

getCallerClass

public static Class getCallerClass(int realFramesToSkip)

Returns the class of the method realFramesToSkip frames up the stack (zero-based), ignoring frames associated with java.lang.reflect.Method.invoke() and its implementation. The first frame is that associated with this method, so getCallerClass(0) returns the Class object for sun.reflect.Reflection. Frames associated with java.lang.reflect.Method.invoke() and its implementation are completely ignored and do not count toward the number of "real" frames skipped.

quickCheckMemberAccess

public static boolean quickCheckMemberAccess(Class memberClass,
                                             int modifiers)

A quick "fast-path" check to try to avoid getCallerClass() calls.

ensureMemberAccess

public static void ensureMemberAccess(Class currentClass,
                                      Class memberClass,
                                      Object target,
                                      int modifiers)
                               throws IllegalAccessException

Throws:

IllegalAccessException

verifyMemberAccess

public static boolean verifyMemberAccess(Class currentClass,
                                         Class memberClass,
                                         Object target,
                                         int modifiers)

registerFieldsToFilter

public static void registerFieldsToFilter(Class containingClass,
                                          String... fieldNames)

registerMethodsToFilter

public static void registerMethodsToFilter(Class containingClass,
                                           String... methodNames)

filterFields

public static Field[] filterFields(Class containingClass,
                                   Field[] fields)

filterMethods

public static Method[] filterMethods(Class containingClass,
                                     Method[] methods)
