Example 1 with PropagatedValueFactory

use of org.apache.cayenne.access.DataDomainSyncBucket.PropagatedValueFactory in project cayenne by apache.

the class FlattenedArcKey method lazyJoinSnapshot.

private Map<String, Object> lazyJoinSnapshot() {
    List<DbRelationship> relList = relationship.getDbRelationships();
    if (relList.size() != 2) {
        throw new CayenneRuntimeException("Only single-step flattened relationships are supported in this operation: %s", relationship);
    }
    DbRelationship firstDbRel = relList.get(0);
    DbRelationship secondDbRel = relList.get(1);
    List<DbJoin> fromSourceJoins = firstDbRel.getJoins();
    List<DbJoin> toTargetJoins = secondDbRel.getJoins();
    Map<String, Object> snapshot = new HashMap<>(fromSourceJoins.size() + toTargetJoins.size(), 1);
    for (DbJoin join : fromSourceJoins) {
        Object value = new PropagatedValueFactory(id1.getSourceId(), join.getSourceName());
        snapshot.put(join.getTargetName(), value);
    }
    for (DbJoin join : toTargetJoins) {
        Object value = new PropagatedValueFactory(id2.getSourceId(), join.getTargetName());
