class ArgumentCount {}

Exception for when an incorrect number of arguments are passed to a method.


Typically, this exception is used when all arguments for a method are optional, but certain arguments need to be passed together, i.e. a method which can be called with no arguments or with two arguments, but not with one argument.

Along the same lines, this exception is also used if a method expects an array with a certain number of elements and the provided number of elements does not comply.
