Class KeyPathValidator

java.lang.Object

com.hotels.road.partition.KeyPathValidator

public class KeyPathValidator
extends Object

Validates that the supplied period delimited path can be used to locate a node in an Avro Schema and related Avro data object. With the exception of NULL, any Avro type can be used as a key. Note that by design individual elements contained within ARRAYs and MAPs cannot be addressed as these are only verifiable at runtime, subject to the context of the message being sent.

If the path is empty, blank, or null then the entire message is used as the key.
