getArrayElementType

public Type getArrayElementType()

Description copied from class: RefLikeType

If I have a variable x of declared type t, what is a good declared type for the expression ((Object[]) x)[i]? The getArrayElementType() method in RefLikeType was introduced even later to answer this question for all classes implementing RefLikeType. If t is an array, then the answer is the same as getElementType(). But t could also be Object, Serializable, or Cloneable, which can all hold any array, so then the answer is Object.
