## Class SessionNode

- java.lang.Object
- - org.modeshape.jcr.cache.document.SessionNode

- All Implemented Interfaces:
    CachedNode, MutableCachedNode

      @ThreadSafe
      public class SessionNode
      extends Object
      implements MutableCachedNode

  A node used within a `session` when that node has (or may have) transient (unsaved) changes. This node is an extension of a `CachedNode`, and thus can be used as a regular cached node. All transient changes are captured as a delta on top of the underlying `workspace node`, and so any changes to the workspace node (made by other sessions' save operations) are immediately reflected.

          protected final Path.Segment getSegment(NodeCache cache,

          public int getDepth(NodeCache cache)
                       throws NodeNotFoundException

      Description copied from interface: `CachedNode`
      Get the depth of this node. The depth is equivalent to the number of segments in the node's path (0 for the root node, 1 for "`/foo`", 2 for "`/foo/bar`", etc.), although this method will likely compute the depth more efficiently that finding the path and asking for the number of segments.

      The depth is calculated based upon the primary parent (and `primary path`). This is, although shared nodes are accessible at multiple paths, only the primary path is used to determine the depth of the node.

      Specified by:
        `getDepth` in interface `CachedNode`
      Parameters:
        `cache` - the cache to which this node belongs, required in case this node needs to use the cache; may not be null
      Returns:
        the depth of this node; 0 for the root, or a positive number for all other nodes

        `NodeNotFoundException` - if this node no longer exists

      Description copied from interface: `CachedNode`

      Returns:
        the node's path; never null with at least one segment for all nodes except the root node

      Returns:

    - #### isQueryable

          public boolean isQueryable(NodeCache cache)

      Description copied from interface: `CachedNode`
      Determine if this node should be indexed and therefore available for querying. By default, every node is queryable, so only in certain cases can a node be made non-queryable.
      Specified by:

      Parameters:
        `cache` - the cache to which this node belongs, required in case this node needs to use the cache; may not be null *
