Signature
bool DValue::is_list() const
Parameters
return value : true when the value is an array with keys 0..n-1
Returns true for map-shaped values that represent a list. An empty map is a list only if it was explicitly put in list mode with set_array() or by list operations. Non-empty lists must have canonical numeric string keys from 0 through size - 1.
Example
DValue list; DValue item; item = "Ada"; list.push(item); print(list.is_list() ? "list\n" : "map\n");
Output
list
