class Roda::RodaPlugins::SinatraHelpers::DelayedBody

write to it.
of using Roda’s default body array and response.write to
Class used when the response body is set explicitly, instead

returned by calling each on the body.
If the body is a String, yield it, otherwise yield each string

def each
  v = value
  if v.is_a?(String)
    yield v
  else
    v.each{|s| yield s}
  end
end

never empty.
Assume that if the body has been set directly that it is

def empty?
  false
end

called until the body is needed.
Save the block that will return the body, it won’t be

def initialize(&block)
  @block = block
end

Return the body as a single string, mostly useful during testing.

def join
  a = []
  each{|s| a << s}
  a.join
end

Calculate the length for the body.

def length
  length = 0
  each{|s| length += s.bytesize}
  length
end

be called multiple times.
Cache the body returned by the block. This way the block won’t

def value
  @value ||= @block.call
end
