HeapSnapshotGraph class

A graph representation of a heap snapshot.

Constructors

HeapSnapshotGraph.fromChunks(List<ByteData> chunks, {bool calculateReferrers = true, bool decodeObjectData = true, bool decodeExternalProperties = true, bool decodeIdentityHashCodes = true})
Populates the HeapSnapshotGraph by parsing the events from the HeapSnapshot stream.

Static Methods

getSnapshot(VmService service, IsolateRef isolate, {bool calculateReferrers = true, bool decodeObjectData = true, bool decodeExternalProperties = true, bool decodeIdentityHashCodes = true}) → Future<HeapSnapshotGraph>
Requests a heap snapshot for a given isolate and builds a HeapSnapshotGraph.
