Method: Newman::Store#initialize

Defined in:

lib/newman/store.rb

#initialize(filename) ⇒ Store

To initialize a ‘Newman::Store` object, a `filename` string must be provided, i.e.

store = Newman::Store.new("simple.store")

This filename will be used to initialize a ‘PStore` object after first running `FileUtils.mkdir_p` to create any directories within the path to the filename if they do not already exist. Once that `PStore` object is created, two root keys will be mapped to empty Hash objects if they are not set already: `:indentifers` and `:columns`.

While it’s okay to treat the ‘PStore` object as an implementation detail, we will treat our interactions with it as part of Newman’s **external interface**, so that we are more conservative about making backwards incompatible changes to the databases created by ‘Newman::Store`.

  FileUtils.mkdir_p(File.dirname(filename))

  self.data = PStore.new(filename)

  write do
    data[:identifiers] ||= {} 
    data[:columns]     ||= {}
  end
