def initialize asset, client, logger
  @asset = asset
  if asset.is_a?(Collins::Asset) then
    @tag = asset.tag
  else
    @tag = asset
  end
  @client = client
  @logger = logger
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(meth, *args, &block) ⇒ Object

Note:

this method should never be called directly

Fill in the missing asset parameter on the dynamic method if needed

If Client responds to the method, and the method requires an ‘asset_or_tag`, we insert the asset specified during initialization into the args array. If the method does not require an `asset_or_tag`, we simply proxy the method call as is. If Client does not respond to the method, we defer to `super`.

Examples:

collins_client.get('some_tag')            # => returns that asset
collins_client.with_asset('some_tag').get # => returns that same asset
