Class DataType

public abstract class DataType extends Object
Base of the Snowpark type hierarchy, as inline Java handlers see it.

Snowpark gives every SQL type its own class so a handler can write field.dataType() instanceof StringType. The stub keeps that shape rather than collapsing the types into one value class, because collapsing them is exactly what stops such a handler compiling.
