getAttributeValue

private java.lang.Object getAttributeValue(java.lang.reflect.Method attributeMethod)

cloneArray

private java.lang.Object cloneArray(java.lang.Object array)

Clone the provided array, ensuring that original component type is retained.

Parameters:

array - the array to clone

annotationEquals

private boolean annotationEquals(java.lang.Object other)

See Annotation.equals(Object) for a definition of the required algorithm.

Parameters:

other - the other object to compare against
