Package org.infinispan.query

Interface Transformer

public interface Transformer

Converts objects (cache keys only) to and from their Java types to String representations so that Infinispan can index them. You need to convert custom types only. Infinispan transforms boxed primitives, java.lang.String, java.util.UUID, and byte arrays internally.

Implementations must be thread-safe! It is recommended they are also stateless.
