Defined in:
lib/bit_magic/bit_field.rb

#read_field(*args) ⇒ Integer Also known as: []

Read the specified bit indices as a group, in the order given

Examples:

Read bits or a list of bits into an integer

bit_field = BitField.new(101) # 1100101 in binary, lsb on the right
bit_field.read_field(0, 1, 2) #=> 5 # or 101
bit_field.read_field(0) #= 1
bit_field.read_field( (2..6).to_a ) #=> 25 # or 11001
