Instance Method Detail
Must yield this collection's elements to the block.
Returns true if self is empty, false otherwise.
([] of Int32).empty? # => true
([1]).empty? # => falseReturns the first element in the collection. Raises Enumerable::EmptyError
if the collection is empty.
([1, 2, 3]).first # => 1
([] of Int32).first # raises Enumerable::EmptyErrorReturns an Array with all the elements in the collection.
(1..5).to_a # => [1, 2, 3, 4, 5]Returns a nicely readable and concise string representation of this object, typically intended for users.
This method should usually not be overridden. It delegates to
#to_s(IO) which can be overridden for custom implementations.
