Service information

From outside the service, you can get information about its input, internal and output attributes.

This can be useful, for example, when implementing complex service processing. Or for testing.

For example, the service describes the following attributes:

class BuildFullName < ApplicationService::Base
  input :first_name, type: String
  input :middle_name, type: String, required: false
  input :last_name, type: String

  internal :prepared_full_name, type: String

  output :full_name, type: String

  # ...
end

You can obtain information about them in the following ways:

BuildFullName.info

# => #<Servactory::Info::Result:0x00000001118c7078 @inputs=[:first_name, :middle_name, :last_name], @internals=[:prepared_full_name], @outputs=[:full_name]>

BuildFullName.info.inputs

# => [:first_name, :middle_name, :last_name]

BuildFullName.info.internals

# => [:prepared_full_name]

BuildFullName.info.outputs

# => [:full_name]
