NDExStore

The NDExStore provides storage and interactions with an NDEx server. The NDExStore contains a lucene store with actions for querying the NDEx repository for networks given a list of search terms. It also contains a server store that contains information about the server and login information. Actions on the server store can change the NDEx target and log in and log out a user.

CyStore Library Name: NDExStore

Note: A CyStore's library name appears in npm, and is the name used for importing the CyStore as a library.

CyStore Registered Name: ndex

Note: The CyStore's registered name appears when it's initialized with the CyFramework in the CyFramework's data model.

Sample Usage

#Create an instance of the CyFramework using the factory method config, pass in the CyStore dependancy list. var cyto = CyFramework.config([NDExStore]) #Dispatch an action to the CyFramework, in this case, we are starting a lucene search for 'brc1' cyto.dispatch(NDExStore.luceneActions.searchFor('brc1') #Get the state of store 'ndex'. This is the data model associated with the NDExStore CyStore. var state = cyto.store('ndex') #Get the list of networks returned from the lucene search, we use .get() because lucene is an immutablejs map. console.log(state.lucene.get('networks'))

lucene
---
> The lucene store is an immutablejs map. The lucene store has a flag indicating whether the client is still searching fo networks (for displaying a spinner, etc). It also containers an error that is filled if the search fails, and a list of networks that contain the results of the previous search.

__Data model__
> ```javascript
  lucene: Map({
    searching: false,
    networkSummaries: Set(),
    error: null
  })

Action Creators

Registed Name: luceneActions

The object under which the action creators are exported under.

searchBegin()

Sets the searching flag to true, use before beginning a search with searchFor/3

searchError(error)

Called from searchFor/3, not normally used elsewhere, sets the error field with the value of error.

Params

• error: An error object that can be inspected to see the error reason of a failed lucene search.

seachFor(server, query, resultSize)

Begins a lucene search agains the server with a query string, this search will either update networkSummaries or error, depending on the outcome of the search. Either way, it will then flip the searching flag to false.

Params

• server: A string, usually taken from the server store to reflect the store's choice of server.
• query: A string, the lucene query to search against NDEx.
• resultSize(OPTIONAL): Default of 50, setting this to a high value will incease the searchTime. This is the max number of results returned by the lucene search.

server

The server store is an immutable map. It containers information about the NDEx server to be used, the username and password, and the log in state of the user. If loggedIn is false, th userName and userPass fields are considered garbage. Actions allow setting the server name and address, and logging the user in and out.

Data model

lucene: Map({ serverName: "Public NDEx", serverAddress: "http://public.ndexbio.org", userName: "", userPass: "", loggedIn: false })
