Constructor Detail

ExecutionGroupEdge

public ExecutionGroupEdge(ExecutionGroupVertex sourceVertex,
                  int indexOfOutputGate,
                  ExecutionGroupVertex targetVertex,
                  int indexOfInputGate,
                  ChannelType channelType,
                  boolean userDefinedChannelType,
                  DistributionPattern distributionPattern)

Constructs a new group edge.

Parameters:

sourceVertex - the source vertex this edge originates from

indexOfOutputGate - the index of the source vertex's output gate this edge originates from

targetVertex - the group vertex to be connected

indexOfInputGate - the index of the consuming task's input gate

channelType - the channel type for the edge

userDefinedChannelType - true if the channel type has been specified by the user, false otherwise

distributionPattern - the distribution pattern to create the wiring
