List all child feature ids of a MoMa NodeΒΆ
For this example we show how to get a list of all child feature ids of a MoMa node.
Lets assume our current MoMa tree looks like the following.
And we have two feature classes like the following.
Feature class innercity.
id | name |
---|---|
1 | innercity_feature_1 |
2 | innercity_feature_2 |
3 | innercity_feature_3 |
Feature class area1.
id | name |
---|---|
12 | area1_feature_1 |
13 | area1_feature_2 |
14 | area1_feature_3 |
We want to get a list of the feature ids belonging to the node Augsburg.
Full code sample
import GSTPy
owner = ni.get_current_gst_user()
levels = ni.list_levels()
models = ni.list_elements(owner, levels[0])
model_links = ni.list_children()
augsburg_model = next((model for model in models if model.label == "Augsburg"))
augsburg_link = next(
(link for link in model_links
if link.target_id == augsburg_model.id and
link.target_type == GSTPy.LinkAdjacencyTargetType.Element))
feature_ids = ni.list_feature_ids_of_link(augsburg_link)
With the example above we can expect the return value as follows. (The order can be different).
>>> print feature_ids
[1, 2, 3, 14, 13, 12]
