typed-array

Gem provides enforced-type functionality to Arrays

Example

Create Standard Class

 require 'typed-array'
 class Things < Array
   extend TypedArray
   restrict_types Thing1,Thing2
 end

Generate Class using Factory

 require 'typed-array'
 things = TypedArray(Thing1,Thing2)

Adding items to the Array

 # All standard Array interfaces are implemented, including block-processing
 # and variable-number of arguments. For methods that would usually return an
 # Array, they instead return an instance of the current class (except to_a).
 #
 # The difference is that if the method would generate an Array including the
 # wrong types, TypedArray::UnexpectedTypeException is raised and the call is
 # aborted before modifying the enforced TypedArray instance.

 require 'typed-array'
 symbols = TypedArray(Symbol).new([:foo,:bar,:baz,:bingo])
 begin
   integers = TypedArray(Integer).new([1,3,7,2,:symbol])
 rescue TypedArray::UnexpectedTypeException
   puts "An error occured: #{$!}"
 end

Methods

Public Instance methods

Provide a factory method. Takes any number of types to accept as arguments and returns a class that behaves as a type-enforced array.
