PathResolver (service 0.11.0 API)

java.lang.Object
- org.ehrbase.aql.sql.PathResolver

```
public class PathResolver
extends Object
```
Resolve the path corresponding to a symbol in a given context
Path are resolved at runtime by performing a query on the CONTAINMENT table. For example to resolve the path of contained archetype 'openEHR_EHR_OBSERVATION_laboratory_test_v0' in composition 'openEHR_EHR_COMPOSITION_report_result_v1', the following query is executed
```
      select "ehr"."containment"."path"
          from "ehr"."containment"
          where (
              "ehr"."containment"."comp_id" = 'b97e9fde-d994-4874-b671-8b1cd81b811c'
              and (label ~ 'openEHR_EHR_COMPOSITION_report_result_v1.*.openEHR_EHR_OBSERVATION_laboratory_test_v0')
          )
      
```
The found path is for example: /content[openEHR-EHR-OBSERVATION.laboratory_test.v0 and name/value='Laboratory test'] it is used then to build the actual path to a datavalue
