public interface Selector
extends Source

Selects a subset of the nodes in the repository based on node type.

A selector selects every node in the repository, subject to access control constraints, that satisfies at least one of the following conditions:

• the node's primary node type is nodeType, or
• the node's primary node type is a subtype of nodeType, or
• the node has a mixin node type that is nodeType, or
• the node has a mixin node type that is a subtype of nodeType.

The query is invalid if nodeType or selectorName is not a syntactically valid JCR name.

The query is invalid if selectorName is identical to the selectorName of another selector in the query.

If nodeType is a valid JCR name but not the name of a node type available in the repository, the query is valid but the selector selects no nodes.

Since:

JCR 2.0
