MeqReqSeq
The request sequencer is used to execute its children in a fixed order. Its result is the result of child result_index.
Initrec
result_index: number of the child of which the result is passed through. Child numbers count from 0.
Example
result_index: number of the child of which the result is passed through. Child numbers count from 0.
A typical example in a simple selfcal application:
1 ns.Sequencer(ant1, ant2) << Meq.ReqSeq(ns.solver, ns.corrected_data(ant1, ant2), result_index=1)
In this example ns.sequencer first executes the ns.solver node, then the ns.corrected_data(ant1, ant2) node. The result of the sequencer is the result of the ns.corrected_data(ant1, ant2) node.
See also MatrixExample.py where a request sequencer is used to send different requests to various matrix manipulation nodes.
