Methods
-
addConn(
Direction dir, bool usefd) → void -
inherited
-
addStream(
Direction dir) → void -
inherited
-
beginSpan(
) → Future< ResourceScopeSpan> -
BeginSpan creates a new span scope rooted at this scope.
inherited
-
decRef(
) → void -
inherited
-
done(
) → void -
Done ends the span and releases associated resources.
inherited
-
incRef(
) → void -
inherited
-
isUnused(
{int ownRefs = 0}) → bool -
Whether nothing uses this scope: it holds no resource and no scope or
span refers to it.
ownRefsreferences are not counted; the resource manager holds one on each peer scope it keeps.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
releaseMemory(
int size) → void -
ReleaseMemory explicitly releases memory previously reserved with ReserveMemory.
inherited
-
removeConn(
Direction dir, bool usefd) → void -
inherited
-
removeStream(
Direction dir) → void -
inherited
-
reparent(
List< ResourceScopeImpl> newEdges) → void -
Moves this scope under
newEdges. Its current resources are counted in the ancestors it gains and released from the ones it loses; an ancestor it keeps (the system scope, usually) keeps counting them once. This is how go-libp2p's SetPeer and SetProtocol juggle resources. Throws, and changes nothing, if a gained ancestor's limit would be exceeded.inherited -
reserveMemory(
int size, int priority) → Future< void> -
ReserveMemory reserves memory/buffer space in the scope; the unit is bytes.
inherited
-
setProtocol(
ProtocolID protocol) → Future< void> -
override
-
setService(
String serviceName) → Future< void> -
override
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
