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   @value = nil
217 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
221 def each
222   v = value
223   if v.is_a?(String)
224     yield v
225   else
226     v.each{|s| yield s}
227   end
228 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
232 def empty?
233   false
234 end
join()

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

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

Calculate the length for the body.

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