Details¶
DropFront
drops (removes) the first element of the sequence variable that has been passed to in the :Name
parameter.
This shard works on both sequences and tables. Parameter :Key
applies only to tables.
Since variables may be locally scoped (created with (:Global false)
; exists only for current wire) or globally scoped (created with (:Global true)
; exists for all wires of that mesh), both parameters :Global
and :Name
are used in combination to identify the correct variable to drop elements from.
Any input to this shard is ignored and instead passed through as its output.
