TTGraph class

In-memory graph: holds node state, runs read/write middleware, merges via the GraphMergePort, and fans data to transports. Transport, query and path-write operations live in the part extensions.

Available extensions

• TTGraphQuery
• TTGraphTransports
• TTGraphWrite

Constructors

TTGraph({GraphMergePort? mergePort})

Properties

activeConnectors ↔ num

getter/setter pair

events ↔ TTGraphEvent

late, final

hashCode → int

no setter, inherited

id ↔ String

late, final

runtimeType → Type

A representation of the runtime type of the object.

Methods

connect(GraphTransportPort transport) → TTGraph

Available on TTGraph, provided by the TTGraphTransports extension

Connect to a source/destination for graph data.

disconnect(GraphTransportPort transport) → TTGraph

Available on TTGraph, provided by the TTGraphTransports extension

Disconnect from a source/destination for graph data.

eachConnector(GraphConnectorFuncType cb) → TTGraph

Available on TTGraph, provided by the TTGraphTransports extension

Retained for compatibility; transports conceal connector types (no-op).

get(String soul, [TTMsgCb? cb, String? msgId]) → VoidCallback

Available on TTGraph, provided by the TTGraphQuery extension

Request node data for soul.

getOpt() → TTGraphOptions

getPathSouls(List<String> path) → Future<List<String>>

Available on TTGraph, provided by the TTGraphQuery extension

Resolve the list of souls addressed by path.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

opt(TTGraphOptions options) → TTGraph

Configure graph options. Currently unused.

put(TTGraphData data, [TTMsgCb? cb, String? msgId]) → VoidCallback

Write node data keyed by soul through write middleware, then trigger the put event and re-ingest locally. Returns a listener-cleanup function.

putPath(List<String> fullPath, TTValue data, [TTMsgCb? cb, UUIDFuncType? uuidFn]) → Future<void>

Available on TTGraph, provided by the TTGraphWrite extension

Write graph data to a potentially multi-level deep path.

query(List<String> path, TTOnCb cb) → VoidCallback

Available on TTGraph, provided by the TTGraphQuery extension

Read a potentially multi-level deep path from the graph.

toString() → String

A string representation of this object.

inherited

unuse(TTMiddleware middleware, {TTMiddlewareType kind = TTMiddlewareType.read}) → TTGraph

Available on TTGraph, provided by the TTGraphTransports extension

Unregister graph middleware previously added with use.

use(TTMiddleware middleware, {TTMiddlewareType kind = TTMiddlewareType.read}) → TTGraph

Available on TTGraph, provided by the TTGraphTransports extension

Register graph middleware (read by default, or write via kind).

Operators

operator ==(Object other) → bool

The equality operator.
