Class IdentityFieldPathUpdateFieldValues

java.lang.Object

com.yahoo.vespa.indexinglanguage.IdentityFieldPathUpdateFieldValues

All Implemented Interfaces:

FieldTypes, FieldValues, UpdateFieldValues

public class IdentityFieldPathUpdateFieldValues
extends Object
implements UpdateFieldValues

No-op update adapter which simply passes through the input update unchanged. I.e. getOutput() will return a DocumentUpdate containing only the FieldPathUpdate the IdentityFieldPathUpdateAdapter was created with. All other applicable calls are forwarded to the provided DocumentAdapter instance. This removes the need for a potentially lossy round-trip of update -> synthetic document -> update.
