public interface NodeOps

extends Serializable

NodeOps is a service for Node CRUD operations. It is used to manage nodes, including their Properties, in a content repository.

NodeOps rules are defined below.

All nodes are uniquely identified through:

• 1) their ID, which contains the uid that uniquely identifies it within the repository. This uid may be the path, a database id, etc.
• 2) their path that uniquely identifies it within a repository. The path should be in unix-like format such as /a/b/c where / is the root and a is the root's child. The path must always begin with / and never end with it. So neither of the following are valid: a/b/c/d or /a/b/d/d/.

All Properties are identified through their ID, which includes the uid that uniquely identifies the Property in the repository.

A Node may either be a Content Node or a Hierarchy Node as defined by its type. A Hierarchy Node may contain both Hierarchy and Content Nodes, but a Conent Node may only contain other Content Nodes.

Node names must not contain either forward, or backslashes.

If a node contains an ObjectClass, it will also contain a Property for each PropertyDefinition of its ObjectClass and each Property will be in the shape as defined by its corresponding PropertyDefinition.

Most operations use ID objects as parameters. Whenever an ID is used, it must not be null. The uid may be null when dealing with root. For example a call to getNodeChildren(ID id) with a correct repository name and a null uid will return all Nodes at root for that repository. It may also be null on create operations, in which the uid has not been created yet, but will be created and returned by the repository.

The repository implementation may have more specific validation rules than that defined above. If a repository considers an attempted operation invalid, it will throw a RepositoryException.

If a Node has an ObjectClass associated with it, whenever it is retrieved it must contain the ObjectClass. However, the Node Properties need not be present as they may be lazy loaded by the call to getProperties() on the Node. For the getNode implementations, it is best to initially set the Properties on the return.

                       RepositoryException

Deprecated

This method creates a new Node underneath the parent. If the parentId's uid is null then the new Node is created under root.

Parameters

parentId - - the id for the parent of the node. The uid is null if the parent is root.

newNodeName - - the name of Node to create.

type - - the type of the node, either Node.HIERARCHY or #CONTENT. Use of Node.HIERARCHY and Node.CONTENT will be deprecated in future releases.

Returns

the newly created node.

Throws

AuthorizationException - - if the user attempting the operation is not authorized to perform it.

NodeExistsException - - if the name for the node already exists as a child of the parent.

RepositoryException - - if validation error occurs.

createNode

Node createNode(ID parentId,
                String newNodeName,
                int type,

                       NoSuchObjectClassException,
                       RepositoryException

Deprecated

This method creates a new Node underneath the parent. If the parent uid is null then the new Node is created under root. It associates the ObjectClass with the given id to the new Node and adds the given properties (content and meta-content) to the Node. If there is a PropertyDefintion in the given ObjectClass with no corresponding Property in the properties array a Property will be created with a null value, unless the Property is required, in which case a validation exception will be thrown.

Parameters

parentId - - the id for the parent of the node. The parentId's uid is null if the parent is root.

newNodeName - - the name of Node to create.

type - - the type of the node, either Node.HIERARCHY or #CONTENT. Use of Node.HIERARCHY and Node.CONTENT will be deprecated in future releases.

objectClassId - The ID of the ObjectClass to use. This can be null, meaning there is no type associated with the node. Without a type, the node cannot have properties.

properties - The properties (and values) of the node. This can be null, even if the 'objectClassId' is non-null.

Returns

the newly created Node.

Throws

AuthorizationException

NodeExistsException - - if the parent Node already has a child with the same name.

NoSuchObjectClassException - - if the ObjectClass doesn't exist.

RepositoryException - - if a validation error occurs.
