I've made some calculations on my network (eigenvector, degree, etc.) and for some nodes i got the result 0 and null (and by null i mean i got nothing - blank record).
What is the difference between those two outcomes?
Zero could mean that a procedure is executed. What that means depends on what your intent behind executing a thing. On the other hand function does return you some value object. Null means its a function that is designed to return null under specific condition. Once that condition changes it might return some other value that caller will use either to introspect or as signal that tells it about the value it represents.
I am running eigenvector centrality in stream mode and am getting all null values returned. You indicate that the function returns null if a condition is met. What condition when met returns null values? Thank you for your help.
