Recursive Printing

Discussion created by johnmdye on Apr 18, 2013
So I have no clue how to do this but I'm 99% positive it's possible...I think.

I need to execute a function against every single feature in a feature class, but in a sequential and recursive manner. So let's say I'm creating a network value for each feature. The network value for each feature depends on the value of other items in the network. So every time the network value for a feature is calculated, all previously calculated values must be recalculated in order to account for the value of the newly calculated feature's network value.

So, let's say I have a feature class

FeatureClass
[TABLE="class: cms_table_cms_table_grid"]IDShapeNameNetwork Value1PointFeature1<Null>2PointFeature2
<Null>3PointFeature3
<Null>4PointFeature4
<Null>5PointFeature5
<Null>
[/TABLE]



I want to calculate the value for Feature1.
[TABLE="class: cms_table_cms_table_grid"]IDShapeNameNetwork Value1PointFeature11002PointFeature2
<Null>3PointFeature3
<Null>4PointFeature4
<Null>5PointFeature5
<Null>
[/TABLE]




Then I want to calculate the value for Feature2.
[TABLE="class: cms_table_cms_table_grid"]IDShapeNameNetwork Value1PointFeature11002PointFeature2
933PointFeature3
<Null>4PointFeature4
<Null>5PointFeature5
<Null>
[/TABLE]



But now there are multiple items in the network which means that now Feature1's network value is possibly incorrect, so Feature1 has to be recalculated..
[TABLE="class: cms_table_cms_table_grid"]IDShapeNameNetwork Value1PointFeature1982PointFeature2
933PointFeature3
<Null>4PointFeature4
<Null>5PointFeature5
<Null>
[/TABLE]



Now calculate the network value for Feature3, then recalculate Feature2, then recalculate Feature1
[TABLE="class: cms_table_cms_table_grid"]IDShapeNameNetwork Value1PointFeature1922PointFeature2
883PointFeature3
764PointFeature4
<Null>5PointFeature5
<Null>
[/TABLE]

So on and so forth until I've calculated a network value for Feature5 and recalculated the values for features 1-4

Then stop the iteration.

any help or info is appreciated...
