Signal Subscriptions
This package implements subscriptions mechanics using signal package.
It defines 3 new RPC methods in the eth namespace and 2 signals.
Methods
###eth_subscribeSignal
Creates a new filter and subscribes to its changes via signals.
Parameters: receives the method name and parameters for the filter that is created.
Example 1:
{
"jsonrpc": "2.0",
"id": 1,
"method": "eth_subscribeSignal",
"params": ["eth_newPendingTransactionFilter", []]
}
Example 2:
{
"jsonrpc": "2.0",
"id": 2,
"method": "eth_subscribeSignal",
"params": [
"shh_newMessageFilter",
[{ "symKeyID":"abcabcabcabc", "topics": ["0x12341234"] }]
]
}
Supported filters: shh_newMessageFilter, eth_newFilter, eth_newBlockFilter, eth_newPendingTransactionFilter
(see Ethereum documentation for respective parameters).
Returns: error or subscriptionID.
###eth_unsubscribeSignal
Unsubscribes and removes one filter by its ID.
NOTE: Unsubscribing from a filter removes it.
Parameters: subscriptionID obtained from eth_subscribeSignal
Returns: error if something went wrong while unsubscribing.
