Public Class methods

new(&block)

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

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
246 def initialize(&block)
247   @block = block
248 end

Public Instance methods

each()

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

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
252 def each
253   v = value
254   if v.is_a?(String)
255     yield v
256   else
257     v.each{|s| yield s}
258   end
259 end
empty?()

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

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
263 def empty?
264   false
265 end
join()

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

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
268 def join
269   a = []
270   each{|s| a << s}
271   a.join
272 end
length()

Calculate the length for the body.

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
275 def length
276   length = 0
277   each{|s| length += s.bytesize}
278   length
279 end
