Defined in:: lib/bindata/uint8_array.rb

Overview

Uint8Array is a specialised type of array that only contains bytes (Uint8). It is a faster and more memory efficient version of BinData::Array.new(:type => :uint8).

require 'bindata'

obj = BinData::Uint8Array.new(initial_length: 5)
obj.read("abcdefg") #=> [97, 98, 99, 100, 101]
obj[2] #=> 99
obj.collect { |x| x.chr }.join #=> "abcde"

Parameters

Parameters may be provided at initialisation to control the behaviour of an object. These params are:

:initial_length:: The initial length of the array. :read_until:: May only have a value of :eof. This parameter instructs the array to read as much data from the stream as possible.
