CPS-766: Get Nodes Endpoint (support multipel to-level nodes)Closed

Implementation Proposal

Creating a new get nodes endpoint

REST Layer

• cpsData.yml

  • New get endpoint for nodesByDataspaceAndAnchor "Get parallel nodes with an option to retrieve all the children for a given anchor and dataspace"

• DataRestController.java

  • New method, getNodesByDataspaceAndAnchor which calls new method getDataNodes from cpsDataService and return obtained datanodes.

• DataRestControllerSpec.groovy

  • Add test for scenario above

Service Layer

• CpsDataService.java

  • new getDataNodes method to be overwritten

• CpsDataServiceImpl.java

  • implement getDataNodes and call getDataNodes from persistence layer

Persistence Layer

• CpsDataPersistenceService.java

  • new method getDataNodes

• CpsDataPersistenceServiceImpl.java

  • implement getDataNodes, call new method getFragmentsByXpath

  • getFragmentsByXpath calls new FragmentRepository method findRootFragmentsByDataspaceAndAnchor if root xpath or new method getFragmentsByDataspaceAndAnchorAndXpath if non root xpath

• FragmentRepository

  • findRootFragmentsByDataspaceAndAnchor obtains nodes when there is no node xpath

  • getFragmentsByDataspaceAndAnchorAndXpath obtains nodes when there is an xpath provided
