“foo #{bar}” ^^^^^^^^^^^^

‘foo` ^^^^^

Visit a heredoc node that is representing a string.

Returns the octet string representation of the elliptic curve point.

conversion_form specifies how the point is converted. Possible values are:

• :compressed

• :uncompressed

• :hybrid

“foo” ^^^^^

“foo” ^^^^^

IO streams for strings, with access similar to IO; see IO.

About the Examples

Examples on this page assume that StringIO has been required:

require 'stringio'

Visit a heredoc node that is representing an xstring.

Objects of class Binding encapsulate the execution context at some particular place in the code and retain this context for future use. The variables, methods, value of self, and possibly an iterator block that can be accessed in this context are all retained. Binding objects can be created using Kernel#binding, and are made available to the callback of Kernel#set_trace_func and instances of TracePoint.

These binding objects can be passed as the second argument of the Kernel#eval method, establishing an environment for the evaluation.

class Demo
  def initialize(n)
    @secret = n
  end
  def get_binding
    binding
  end
end

k1 = Demo.new(99)
b1 = k1.get_binding
k2 = Demo.new(-3)
b2 = k2.get_binding

eval("@secret", b1)   #=> 99
eval("@secret", b2)   #=> -3
eval("@secret")       #=> nil

Binding objects have no class-specific methods.
