Methods

Create(ActorSystem)

Declaration

public static ActorMaterializerSettings Create(ActorSystem system)

Parameters

Type	Name	Description
ActorSystem	system

Returns

Type	Description
ActorMaterializerSettings

Equals(object)

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
object	obj

Returns

Type	Description
bool

Overrides

object.Equals(object)

GetHashCode()

Declaration

public override int GetHashCode()

Returns

Type	Description
int

Overrides

object.GetHashCode()

WithAutoFusing(bool)

TBD

Declaration

public ActorMaterializerSettings WithAutoFusing(bool isAutoFusing)

Parameters

Type	Name	Description
bool	isAutoFusing	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithDebugLogging(bool)

Enable to log all elements that are dropped due to failures (at DEBUG level).

Declaration

public ActorMaterializerSettings WithDebugLogging(bool isEnabled)

Parameters

Type	Name	Description
bool	isEnabled	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithDispatcher(string)

This setting configures the default dispatcher to be used by streams materialized with the ActorMaterializer. This can be overridden for individual parts of the stream topology by using ActorAttributes.Dispatcher.

Declaration

public ActorMaterializerSettings WithDispatcher(string dispatcher)

Parameters

Type	Name	Description
string	dispatcher	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithFuzzingMode(bool)

Test utility: fuzzing mode means that GraphStage events are not processed in FIFO order within a fused subgraph, but randomized.

Declaration

public ActorMaterializerSettings WithFuzzingMode(bool isFuzzingMode)

Parameters

Type	Name	Description
bool	isFuzzingMode	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithInputBuffer(int, int)

Each asynchronous piece of a materialized stream topology is executed by one Actor that manages an input buffer for all inlets of its shape. This setting configures the default for initial and maximal input buffer in number of elements for each inlet. This can be overridden for individual parts of the stream topology by using Attributes.InputBuffer.

Declaration

public ActorMaterializerSettings WithInputBuffer(int initialSize, int maxSize)

Parameters

Type	Name	Description
int	initialSize	TBD
int	maxSize	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithMaxFixedBufferSize(int)

Configure the maximum buffer size for which a FixedSizeBuffer will be preallocated. This defaults to a large value because it is usually better to fail early when system memory is not sufficient to hold the buffer.

Declaration

public ActorMaterializerSettings WithMaxFixedBufferSize(int maxFixedBufferSize)

Parameters

Type	Name	Description
int	maxFixedBufferSize	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithOutputBurstLimit(int)

Maximum number of elements emitted in batch if downstream signals large demand.

Declaration

public ActorMaterializerSettings WithOutputBurstLimit(int limit)

Parameters

Type	Name	Description
int	limit

Returns

Type	Description
ActorMaterializerSettings

WithStreamRefSettings(StreamRefSettings)

Declaration

public ActorMaterializerSettings WithStreamRefSettings(StreamRefSettings settings)

Parameters

Type	Name	Description
StreamRefSettings	settings

Returns

Type	Description
ActorMaterializerSettings

WithSubscriptionTimeoutSettings(StreamSubscriptionTimeoutSettings)

Leaked publishers and subscribers are cleaned up when they are not used within a given deadline, configured by StreamSubscriptionTimeoutSettings.

Declaration

public ActorMaterializerSettings WithSubscriptionTimeoutSettings(StreamSubscriptionTimeoutSettings settings)

Parameters

Type	Name	Description
StreamSubscriptionTimeoutSettings	settings	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithSupervisionStrategy(Decider)

Decides how exceptions from application code are to be handled, unless overridden for specific flows of the stream operations with ActorAttributes.SupervisionStrategy

Declaration

public ActorMaterializerSettings WithSupervisionStrategy(Decider decider)

Parameters

Type	Name	Description
Decider	decider	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD

WithSyncProcessingLimit(int)

Limit for number of messages that can be processed synchronously in stream to substream communication

Declaration

public ActorMaterializerSettings WithSyncProcessingLimit(int limit)

Parameters

Type	Name	Description
int	limit	TBD

Returns

Type	Description
ActorMaterializerSettings	TBD
