"""The conversation and replies adapters
|
||
|
|
|
||
|
|
The conversation is responsible for storing all comments. It provides a
|
||
|
|
dict-like API for accessing comments, where keys are integers and values
|
||
|
|
are IComment objects. It also provides features for finding comments quickly.
|
||
|
|
|
||
|
|
The two IReplies adapters - one for the IConversation and one for IComment -
|
||
|
|
manipulate the same data structures, but provide an API for finding and
|
||
|
|
manipulating the comments directly in reply to a particular comment or at the
|
||
|
|
top level of the conversation.
