Instance Method Details

#[](token) ⇒ Module, ...

subscripting a JSI schema module or a NotASchemaModule will subscript the node, and if the result is a JSI::Schema, return the JSI Schema module of that schema; if it is a PathedNode, return a NotASchemaModule; or if it is another value (a basic type), return that value.

Parameters:

  • token (Object)

Returns:

def [](token)
  sub = @possibly_schema_node[token]
  if sub.is_a?(JSI::Schema)
    sub.jsi_schema_module
  elsif sub.is_a?(JSI::PathedNode)
    NotASchemaModule.new(sub)
  else
    sub
  end
end

#name_from_ancestor ⇒ String?

a name relative to a named schema module of an ancestor schema. for example, if Foos = JSI::JSONSchemaOrgDraft07.new_schema_module({'items' => {}}) then the module Foos.items will have a name_from_ancestor of "Foos.items"

Returns:

  • (String, nil)
