Enumerator::Chain.new

Enumerator::Chain.new(*enums) → enum

static VALUE
enum_chain_initialize(VALUE obj, VALUE enums)
{
    struct enum_chain *ptr;

    rb_check_frozen(obj);
    TypedData_Get_Struct(obj, struct enum_chain, &enum_chain_data_type, ptr);

    if (!ptr) rb_raise(rb_eArgError, "unallocated chain");

    return obj;
}

Generates a new enumerator object that iterates over the elements of given enumerable objects in sequence.

Example

e = Enumerator::Chain.new(1..3, [4, 5])
e.to_a #=> [1, 2, 3, 4, 5]
e.size #=> 5
