Determines whether or not this annotation is equivalent to the annotation passed. This is determined according to the following rules:

• Two annotations x and y are equal if and only if they are members of the same annotation type and all the member values of x are equal to the corresponding member values of y.
• The equality of primitive member values x and y is determined (in a way similar to) using the corresponding wrapper classes. For example, Integer.valueOf(x).equals(Integer.valueOf(y) is used for int values. Note: The behavior is identical to the == operator for all but the floating point type, so the implementation may as well use == in these cases for performance reasons. Only for the float and double types the result will be slightly different: NaN is equal to NaN, and -0.0 is equal to 0.0, both of which is normally not the case.
• The equality of two array member values x and y is determined using the corresponding equals(x, y) helper function in Java.Util.Arrays.
• The hash code for all other member values is determined by simply calling their equals() method.
