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
214 def initialize(&block)
215   @block = block
216 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
220 def each
221   v = value
222   if v.is_a?(String)
223     yield v
224   else
225     v.each{|s| yield s}
226   end
227 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
231 def empty?
232   false
233 end
join()

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

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
236 def join
237   a = []
238   each{|s| a << s}
239   a.join
240 end
length()

Calculate the length for the body.

[show source] 
    # File lib/roda/plugins/sinatra_helpers.rb
243 def length
244   length = 0
245   each{|s| length += s.bytesize}
246   length
247 end
