Denotes a snippet parameter representing 0 or more arguments that will be bound during
snippet template
instantiation. During snippet
template creation, its value must be an array whose length specifies the number of arguments
(the contents of the array are ignored) bound to the parameter during
instantiation.
Such a parameter must be used in a counted loop in the snippet preceded by a call to
ExplodeLoopNode.explodeLoop()
. The counted looped must be a standard iteration over
all the loop's elements (i.e.
for (T e : arr) ...
).
