typed-array

Gem provides enforced-type functionality to Arrays

Ryan Biesemeyer mailto:[email protected]

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
