Interface FlowEdge

All Known Implementing Classes:

BaseFlowEdge

@Alpha
public interface FlowEdge

Representation of an edge in a FlowGraph. Each FlowEdge encapsulates:

• two DataNodes as its end points
• a that responsible for data movement between the s.
• a list of SpecExecutors where the FlowTemplate can be executed.

Method Detail

getSrc

String getSrc()

Returns:

the source DataNode id of the edge.

getDest

String getDest()

Returns:

the destination DataNode id of the edge.

getFlowTemplate

FlowTemplate getFlowTemplate()

Returns:

the FlowTemplate that performs the data movement along the edge.

getExecutors

List<SpecExecutor> getExecutors()

Returns:

a list of SpecExecutors that can execute the FlowTemplate corresponding to this edge.

getConfig

com.typesafe.config.Config getConfig()

Get the properties that defines the FlowEdge. Encapsulates all the properties from which the FlowEdge is instantiated. It also includes properties needed for resolving a JobTemplate.

Returns:

the properties of this edge as a Config object.

getId

String getId()

Returns:

the label of the FlowEdge.

isActive

boolean isActive()
