#to_generate_object(&block_) ⇒ Object

Provide a block to call to generate the appropriate object given a tuple. This block is called when the repository is asked to lookup an object given a tuple, and the provided tuple is not yet present.

The block may take up to three arguments. The first is the tuple. The second is the repository containing the object. The third is a hash of arguments passed to the repository’s lookup method.

The block should return the generated object, or nil if it is unable to generate an object for the given tuple.

#to_generate_tuple(&block_) ⇒ Object
