Instance Method Details

#each_with_floe ⇒ Object

For each element in the array, calls the block with two arguments: the element and a “floe” object.

  ary.each_with_floe do |element, floe|
    if floe.first?
        puts "#{element} is the first element"
    end
    if floe.last?
        puts "#{element} is the last element"
    end
    if floe.odd?
        puts "#{element} is an odd-numbered element"
    end
    if floe.even?
        puts "#{element} is an even-numbered element"
    end
end

If no block is given, an enumerator is returned instead.

#each_with_index_floe ⇒ Object

For each element in the array, calls the block with three arguments: the element, its index, and a “floe” object.

ary.each_with_index_floe do |element, i, floe|
    assert_equal(i == 0,        floe.first?)
    assert_equal(i == ary.last, floe.last?)
    assert_equal(i % 2 == 1,    float.odd?)
    assert_equal(i % 2 == 1,    float.even?)
end

If no block is given, an enumerator is returned instead.
