class StructFu::Int

Ints all have a value, an endianness, and a default value. Note that the signedness of Int values are implicit as far as the subclasses are concerned; #to_i and #to_f will return Integer/Float versions of the input value, instead of attempting to unpack the pack value. (This can be a useful hint to other functions).

Public Instance Methods

read(i) click to toggle source

Reads either an Integer or a packed string, and populates the value accordingly.

# File lib/packetfu/structfu.rb, line 88
def read(i)
  self.v = i.kind_of?(Integer) ? i.to_i : i.to_s.unpack(@packstr).first
  self
end
to_f() click to toggle source

Returns the Int as a Float.

# File lib/packetfu/structfu.rb, line 79
def to_f
  (self.v || self.d).to_f
end
to_i() click to toggle source

Returns the Int as an Integer.

# File lib/packetfu/structfu.rb, line 74
def to_i
  (self.v || self.d).to_i
end
to_s() click to toggle source

This is a parent class definition and should not be used directly.
