methods/* These files define all methods callable under web3.db.* web3.eth.* web3.net.* web3.personal.* web3.shh.*
Methods and properties are first defined as a dictionary
and then are converted to real functions and attached to the
respective objects. This will make it easier to mirror the
next migrations of the web3.js library. Both types are defined
in method.py and property.py respectively.
RequestManager Is supplied with one Provider at initialisation which can be replaced by calling setProvider(). It uses Jsonrpc to convert the methods into raw payloads and to validate responses attained with receive().
Has three other methods:
- send(data, timeout=None)
If timeout is None, send blocks until the result is
available, which it then returns.
If the timeout is 0, send returns immediately, only
returning the id of the request, which can be used
to poll with receive() later.
If the timeout is greater than 0, it blocks until
either the result is available or the timeout is
reached, at which point a ValueError is thrown.
send() makes use of the other two functions:
- forward(data)
Forwards the data to the provider and returns the
request id.
- receive(requestid, timeout=0)
Implements the timeout functionality described in send.
If timeout is 0, it returns None if the response was
not available.
Provider On initialisation, is started in a separate thread. Continuously fetches incoming requests from a queue and appends the responses to another queue. Providers only receives and returns "raw" requests, JSON validation and decoding happens in the Request Manager.
As of now there are two implementations:
- RPCProvider
- IPCProvider
