Example 1 with Path

use of com.blazebit.persistence.Path in project blaze-persistence by Blazebit.

the class AbstractCommonQueryBuilder method getPath.

public Path getPath(String path) {
    if (path == null || path.isEmpty()) {
        JoinNode node = joinManager.getRootNodeOrFail("No or multiple query roots, can't find single root!");
        return new SimplePathReference(node, null, node.getType());
    }
    PathExpression pathExpression = expressionFactory.createPathExpression(path);
    joinManager.implicitJoin(pathExpression, true, true, true, null, null, new HashSet<String>(), false, false, true, false);
    // If we expose the path to the outside world, we can't remove it if it is a default select node
    if (pathExpression.getPathReference() != null) {
        selectManager.removeDefaultSelectNode((JoinNode) pathExpression.getBaseNode());
    }
    return (Path) pathExpression.getPathReference();
