Overview

Instance Attribute Summary (collapse)

• - (Object) element_class readonly

  Returns the value of attribute element_class.

Instance Method Summary (collapse)

• - (Object) &(ar)

  Overloaded from Array#&, checks for appropriate class of argument elements.

• - (Object) +(ar)

  Overloaded from Array#+, checks for appropriate class of argument elements.

• - (Object) -(ar)

  Overloaded from Array#-, so that an ArrayOf is returned.

• - (Object) <<(el)

  Overloaded from Array#<<, checks for appropriate class of argument.

• - (Object) concat(ar)

  Overloaded from Array#concat, checks for appropriate class of argument elements.

• - (Object) downcase

  We introduce the 'downcase' method, which maps downcase() to all the Array elements, properly failing when the elements don't have a downcase method.

• - (ArrayOf) initialize(kl, ar = []) constructor

  Create a new ArrayOf whose elements are supposed to be all of type kl, optionally filling it with the elements from the Array argument.

• - (Object) insert(idx, *ar)

  Overloaded from Array#insert, checks for appropriate class of argument elements.

• - (Object) inspect
• - (Object) push(*ar)

  Overloaded from Array#push, checks for appropriate class of argument elements.

• - (Object) replace(ar)

  Overloaded from Array#replace, checks for appropriate class of argument elements.

• - (Object) unshift(*els)

  Overloaded from Array#unshift, checks for appropriate class of argument(s).

• - (Boolean) valid?

  This method checks that all elements are of the appropriate class.

• - (Object) validate

  This method is similar to the above, except that it raises an exception if the receiver is not valid.

• - (Boolean) will_accept?(*els)

  This method checks if the passed arguments are acceptable for our ArrayOf.

• - (Object) |(ar)

  Overloaded from Array#|, checks for appropriate class of argument elements.
