Here's some code from my project that does it. Unfortunately it's quite
complicated.
some helper methods:
protected FlowBuilder base() {
return new FlowBuilder()
.setTableId(getTableId())
.setBarrier(false)
.setHardTimeout(0)
.setIdleTimeout(0);
}
public static Instructions gotoTableInstructions(short tableId) {
return new InstructionsBuilder()
.setInstruction(ImmutableList.of(new InstructionBuilder()
.setOrder(Integer.valueOf(0))
.setInstruction(gotoTableIns(tableId))
.build()))
.build();
}
public static final InstanceIdentifier<Node>
createNodePath(final NodeId nodeId) {
return InstanceIdentifier.builder(Nodes.class)
.child(Node.class, new NodeKey(nodeId))
.build();
}
/**
* Creates a table path from a node ID and table ID
*
* @param nodePath
* @param tableKey
* @return
*/
public static final InstanceIdentifier<Table>
createTablePath(final NodeId nodeId,
final short tableId) {
return createNodePath(nodeId).builder()
.augmentation(FlowCapableNode.class)
.child(Table.class, new TableKey(tableId))
.build();
}
/**
* Creates a path for particular flow, by appending flow-specific
information
* to table path.
*
* @param table
* @param flowKey
* @return
*/
public static InstanceIdentifier<Flow>
createFlowPath(final InstanceIdentifier<Table> table,
final FlowKey flowKey) {
return table.child(Flow.class, flowKey);
}
/**
* Creates a path for particular flow, by appending flow-specific
information
* to table path.
*
* @param table
* @param flowId
* @return
*/
public static InstanceIdentifier<Flow>
createFlowPath(final InstanceIdentifier<Table> table,
final FlowId flowId) {
return createFlowPath(table, new FlowKey(flowId));
}
The actual code cobbled together from a few other helpers:
ReadWriteTransaction t = ctx.dataBroker.newReadWriteTransaction();
InstanceIdentifier<Table> tiid =
FlowUtils.createTablePath(nodeId, getTableId());
Optional<Table> r =
t.read(LogicalDatastoreType.CONFIGURATION, tiid).get();
FlowBuilder flowb = base()
.setId(flowid)
.setPriority(Integer.valueOf(200))
.setMatch(new MatchBuilder()
.setInPort(port)
.build())
.setInstructions(FlowUtils.gotoTableInstructions((short)(getTableId()+1)));
writeFlow(t, tiid, flowb.build());
t.put(LogicalDatastoreType.CONFIGURATION,
FlowUtils.createFlowPath(tiid, flow.getId()),
flow);
