Identify Children of Chart
This chart has two children, state A
and a default transition. State A
has four children, state A1
, state A2
, and two transitions.
Open the model and access the Stateflow.Chart
object for the chart.
open_system("sfHierarchyAPIExample") ch = find(sfroot,"-isa","Stateflow.Chart");
Identify the children of the chart. Display the object types of the children.
children = getChildren(ch); classes = arrayfun(@class,children,UniformOutput=false)
classes = 2x1 cell
{'Stateflow.State' }
{'Stateflow.Transition'}
One element in children
is a state. Display the name of the state.
idx = (classes=="Stateflow.State");
state = children(idx);
state.Name
ans = 'A'
Identify the children of state A
. Display the object types of the children.
grandchildren = getChildren(state); classes = arrayfun(@class,grandchildren,UniformOutput=false)
classes = 4x1 cell
{'Stateflow.State' }
{'Stateflow.State' }
{'Stateflow.Transition'}
{'Stateflow.Transition'}
Two elements in grandchildren
are states. Display the names of the states.
idx = (classes=="Stateflow.State");
grandchildren(idx).Name
ans = 'A1'
ans = 'A2'
