All Known Implementing Classes:

DefaultPiPipeconf

@Beta
public interface PiPipeconf

Configuration of a protocol-independent pipeline that includes a pipeline model, a collection of pipeline-specific behaviour implementations, and extensions.

Nested Classes

Modifier and Type	Interface and Description
static class	PiPipeconf.ExtensionType Type of extension of a protocol-independent pipeline configuration.

Method Summary

Modifier and Type	Method and Description
Collection<Class<? extends Behaviour>>	behaviours() Returns all pipeline-specific behaviour interfaces defined by this configuration.
Optional<InputStream>	extension(PiPipeconf.ExtensionType type) Returns, if present, an input stream pointing at the beginning of a file representing a device-specific or control protocol-specific extension of this configuration.
long	fingerprint() Returns the fingerprint of pipeconf.
boolean	hasBehaviour(Class<? extends Behaviour> behaviourClass) Indicates whether or not the pipeconf supports the specified class of behaviour.
PiPipeconfId	id() Returns the identifier of this pipeline configuration.
Optional<Class<? extends Behaviour>>	implementation(Class<? extends Behaviour> behaviour) Returns the implementation class for the given behaviour, if present.
PiPipelineModel	pipelineModel() Returns the pipeline model.

Method Detail

id

PiPipeconfId id()

Returns the identifier of this pipeline configuration.

Returns:

a identifier

pipelineModel

PiPipelineModel pipelineModel()

Returns the pipeline model.

Returns:

a pipeline model

fingerprint

long fingerprint()

Returns the fingerprint of pipeconf.

Returns:

a fingerprint

behaviours

Collection<Class<? extends Behaviour>> behaviours()

Returns all pipeline-specific behaviour interfaces defined by this configuration.

Returns:

a collection of behaviours

implementation

Optional<Class<? extends Behaviour>> implementation(Class<? extends Behaviour> behaviour)

Returns the implementation class for the given behaviour, if present.

Parameters:

behaviour - behaviour interface

Returns:

implementation class

hasBehaviour

boolean hasBehaviour(Class<? extends Behaviour> behaviourClass)

Indicates whether or not the pipeconf supports the specified class of behaviour.

Parameters:

behaviourClass - behaviour class

Returns:

true if behaviour is supported

extension

Optional<InputStream> extension(PiPipeconf.ExtensionType type)

Returns, if present, an input stream pointing at the beginning of a file representing a device-specific or control protocol-specific extension of this configuration. For example, if requesting a target-specific P4 binary, this will return the same bytes produced by the P4 compiler.

Parameters:

type - extension type

Returns:

extension input stream
