StreamPipeline

public StreamPipeline(StreamGenerator generatorNode)

Parameters:

generatorNode -

Method Details

getUpstream

public List<Node> getUpstream()

Description copied from interface: Node

Returns the list of upstream nodes, ie. nodes which output is required in order to execute the current node. For Source nodes, this should be empty. For Pipe and Sink nodes, this should be a list of size 1. For Join nodes, this should be a list of size 2.

Returns:

the list of upstream nodes

getRequirements

public List<Node> getRequirements()

Description copied from interface: Node

Returns the list of upstream requirement nodes, ie. nodes which need to be executed before, but which outputs aren't required for execution. There can be any number of requirements for a given node.

Specified by:

getRequirements in interface Node

Overrides:

getRequirements in class AbstractNode

Returns:

the list of upstream requirement nodes

after

public Node after(Node other)

Description copied from interface: Node

Requests for the current node to be executed after the provided node. It should result in the current node having a requirement towards the provided node.

Specified by:

after in interface Node

Overrides:

after in class AbstractNode

Parameters:

other - the node after which it has to be executed

Returns:

the current node

See Also:

Node.getRequirements()

after

public Node after(Collection<Node> others)

Description copied from interface: Node

Requests for the current node to be executed after the provided nodes. It should result in the current node having a requirement towards each node in the provided collection.

Specified by:

after in interface Node

Overrides:

after in class AbstractNode

Parameters:

others - the nodes after which it has to be executed

Returns:

the current node
