Package core implements Neo ledger functionality.
|
|
It's built around the Blockchain structure that maintains state of the ledger.
|
|
|
|
Events
|
|
|
|
You can subscribe to Blockchain events using a set of Subscribe and Unsubscribe
|
|
methods. These methods accept channels that will be used to send appropriate
|
|
events, so you can control buffering. Channels are never closed by Blockchain,
|
|
you can close them after unsubscription.
|
|
|
|
Unlike RPC-level subscriptions these don't allow event filtering because it
|
|
doesn't improve overall efficiency much (when you're using Blockchain you're
|
|
in the same process with it and filtering on your side is not that different
|
|
from filtering on Blockchain side).
|
|
|
|
The same level of ordering guarantees as with RPC subscriptions is provided,
|
|
albeit for a set of event channels, so at first transaction execution is
|
|
announced via appropriate channels, then followed by notifications generated
|
|
during this execution, then followed by transaction announcement and then
|
|
followed by block announcement. Transaction announcements are ordered the same
|
|
way they're stored in the block.
|
|
|
|
Be careful using these subscriptions, this mechanism is not intended to be used
|
|
by lots of subscribers and failing to read from event channels can affect
|
|
other Blockchain operations.
