jarrayp

Arguments: object &optional modifier

With only one argument, this function is a predicate that returns nil if the object is not a remote reference to a Java array. When the result is true, the value is the rank of the array.

If the optional argument is the keyword :dim, the value returned is nil or a list of the dimensions of the array.

If the optional argument is an integer smaller than the rank of the array, then the value returned is the maximum index in the specified dimension.
