##
# Apply a mapping function before calling
# a base output.
#
# Note that this is applied *before* the base output.
# This is different than {SoberSwag::Reporting::Input::Mapped}, which does the reverse.
# IE, this class does `call block -> pass result to base output`,
# while the other does `call serializer -> pass result to block`.
#
# If you want to get *really* nerdy, this is *contravariant* to `Mapped`.
#
# This lets you do things like making an output that serializes to strings via `to_s`:
#
# ```ruby
# ToSTextOutput = SoberSwag::Reporting::Output::ViaMap.new(
# SoberSwag::Reporting::Output.text,
# proc { |arg| arg.to_s }
# )
#
# class Person
# def to_s
# 'Person'
# end
# end
#
# ToSTextOutput.call(Person.new) # => 'Person'
# ```
class ViaMap < Base
def initialize(output, mapper)
@output = output
@mapper = mapper
end
##
# @return [Interface] base output
attr_reader :output
##
# @return [#call] mapping function
attr_reader :mapper
def call(input)
output.call(mapper.call(input))
end
def serialize_report(input)
output.serialize_report(mapper.call(input))
end
def view(view)
ViaMap.new(output.view(view), mapper)
end
def views
output.views
end
def swagger_schema
output.swagger_schema
