Hi!

I have a graph with several objects (s1...sn). All the objects are subobjects of a main object (m).

for each s1..sn I am generating dynamic ports. The criteria for ports is the direction property.

I am wondering if it is somehow possible to use object instead of each subobject while navigating the graph. For example.

foreach .m

{

if :direction = 'in'

then

endif

}

Generators allow to access and select subobjects in many ways. If s and m are in different graph types then you need to access the subgraph and the objects there, like for each m:

do decompositions {
foreach .s; where :direction = 'in' {
id newline
}
}

If you need to access only s1..sn which are used in relationships of m1, then you may access them directly from the ports as follows:

foreach .m {
do #() where :direction = 'in' { /* gives ports connected */

id newline

}

If instances of s and m are in the same graph, then you may access them:

foreach .m {
foreach .s; where :direction = 'in' {
id newline
}
}

When accessing instances of s you may also sort them in different ways, like based on their properties, coordinates etc.
