end

#find(id, pool = nil) {|object| ... } ⇒ any

Find object by ‘id` and `pool`.

There are two ways to specify a pool:

- use the `pool` argument
- when `pool` is `nil` and `id` contains a colon, it is parsed as
  `<pool>:<id>`

Parameters:

  • id (String)
  • pool (String, Pool, nil) (defaults to: nil)

Yield Parameters:

  • object (any)

Returns:

  • (any)
