Interface DataTarget<T>

Type Parameters:

T - Target type

All Superinterfaces:

Expression, Path<T>, Path.FinalPath<T>, Serializable

All Known Subinterfaces:

RelationalTarget<T>

public interface DataTarget<T>
extends Path.FinalPath<T>

Representation of the target element of a data model persistence/query operation.

A DataTarget is a Path, so the target data model entity is represented by a String path name. The path is final, i.e. does not support a parent.

A DataTarget.DataTargetResolver can be used to resolve a symbolic named data target into a persistence model specific data target representation.

5.0.0
