在Cypher CREATE子句中指定属性的基本类型

Question

Contrary to what's possible with the Java API, there doesn't seem to be a way to specify whether a numeric property is a byte , short , int or long :

CREATE (n:Test {value: 1}) RETURN n

always seems to create a long property. I've tried toInt() , but it is obviously understood in the mathematical sense of "integer" more than in the computer data type sense.

Is there some way I'm overlooking to actually force the type?

We have defined a model and want to insert test data using Cypher statements, but the code using the data then fails with a ClassCastException since the types don't match.

If you run your cypher queries with the embedded API then you can provide parameters in a hashmap with the correctly typed values.

For remote users it doesn't really matter as it goes through JSON serialization back and forth which looses the type information anyway. So it is just "numeric".

Why do you care about the numeric type?

you can also just use ((Number)n.getProperty("value")).xxxValue() (xxx = int,long,byte)
