Class TenantlessPathSerializer

java.lang.Object

com.fasterxml.jackson.databind.JsonSerializer<org.hawkular.inventory.paths.Path>

org.hawkular.inventory.json.TenantlessPathSerializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable

public final class TenantlessPathSerializer
extends com.fasterxml.jackson.databind.JsonSerializer<org.hawkular.inventory.paths.Path>

Used to strip the tenant from the canonical path when serializing it.

Note that while the stripping can be done using a custom serializer statelessly, the re-introduction of the tenant id to the paths needs manual intervention because the resolution is contextual - it depends on the tenant ID as well as the intended type of the target entity and the path that the path is relative against (if the path is relative). That's why the DetypedPathDeserializer contains a couple of static methods to inject this context into it.

So while this serializer is universally usable, the deserializer is not. It can only be used in places that can reliably inject the necessary state before the deserialization occurs.

To use this path serializer to serialize canonical (and relative) paths, you need to configure Jackson for example by providing a mixin class with custom annotations.
