Method Detail

getVertices

public Iterable<DefaultLogicalVertex> getVertices()

Description copied from interface: Topology

Returns an iterable over all vertices, topologically sorted.

Specified by:

getVertices in interface Topology<JobVertexID,IntermediateDataSetID,DefaultLogicalVertex,DefaultLogicalResult>

Returns:

topologically sorted iterable over all vertices

containsCoLocationConstraints

public boolean containsCoLocationConstraints()

Description copied from interface: Topology

Returns whether the topology contains co-location constraints. Co-location constraints are currently used for iterations.

Specified by:

containsCoLocationConstraints in interface Topology<JobVertexID,IntermediateDataSetID,DefaultLogicalVertex,DefaultLogicalResult>

Returns:

whether the topology contains co-location constraints
