Class PartTree

java.lang.Object
  org.springframework.data.repository.query.parser.PartTree

All Implemented Interfaces:

Iterable<PartTree.OrPart>

public class PartTree
extends Object
implements Iterable<PartTree.OrPart>

Class to parse a String into a tree or PartTree.OrParts consisting of simple PartTree.OrPart instances in turn. Takes a domain class as well to validate that each of the PartTree.OrParts are refering to a property of the domain class. The PartTree can then be used to build queries based on its API instead of parsing the method name for each query execution.
