Interface INodeManager

public interface INodeManager

Interface to access and manage content node information in the repository, while honoring security(DA/Visitor) constraints placed on them.

Methods returning an ISortableFilterablePagedList may perform sorting and filtering. See the documentation in com.bea.content.paging and Node.

Note: new methods may be added to this interface periodically -- therefore, this not a good CM extension point. The recommended extension point is at the Service Provider Interface, in package com.bea.content.spi.

This interface is intended to be implemented only by BEA Weblogic Portal.BEA Systems reserves the right to add abstract methods to this interface without notice. Implementations of this interface by other parties must not be expected to compile without change in future versions of BEA Weblogic Portal.

Method Detail

addNode

Node addNode(ContentContext context,
             String relPath,
             String primaryNodeTypeName,
             Property[] props)
             throws AuthorizationException,
                    NodeExistsException,
                    NoSuchObjectClassException,
                    RepositoryException

This method adds a new node to the repository. This operation will honor the security capabilities set on the parent node. For example, if the user does not have CREATE capabilities on the parent node, or INSTANTIATE capabilities on the type of the node, the operation might fail.

Parameters

context - The ContentContext Object

relPath - The absolute path to this node, appended with the node's name. For example /A/B/C indicates a node C being added under the parent node B.

primaryNodeTypeName - The type name of the node to create.

props - The properties of the node

Returns

The newly created node.

Throws

AuthorizationException - - if the user does not have CREATE capability on the parent node, or if the user does not have INSTANTIATE capability on the type of the node. This exception will also be thrown if the user is not authorizated by the repository.

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

NoSuchObjectClassException - - if the node's ObjectClass doesn't exist.

RepositoryException - - for any other exception

getNodeByUUID

Node getNodeByUUID(ContentContext context,
                   ID nodeId)
                   throws AuthenticationException,
                          AuthorizationException,
                          NoSuchNodeException,
                          RepositoryException

This method gets a particular Node based on its ID. If there is an ObjectClass associated with it then it along with the Node Properties will be contained in the Node.

If a Property is Binary, then the bytes will not be contained in the BinaryValue. In order to get the bytes a call to (@link #getStream} is necessary. Before retrieving the node it will see if the node has VIEW capability on it. If the capability is not set, the method will disallow the operation & throw an exception.

Parameters

context - The contentContext object

nodeId - - the ID for the node to get. The ID must include the repository and uid.

Returns

Node - the retrieved Node.

Throws

AuthenticationException - - if the user attempting the operation isn't authenticated against the repository.

AuthorizationException - - if the user does not have VIEW capability on the node This exception will also be thrown if the user is not authorizated by the repository.

NoSuchNodeException - - if the node to get can't be found.

RepositoryException - - for any other exception

This method retrieves the Binary data for the given Node and its property. This method returns the binary data of the property of the PUBLISHED node [if you have a versioning enabled repository] After calling this method and retrieving the InputStream, you must close the InputStream when finished reading it in a finally block. If this is a nested property type, the name will reflect the nested hierarchy with NESTED_DELIMITER between each parent and child property name. The delimiter is not valid for use within the actual name, only to seperate the parent/child names. If the nested property type is multi-valued, then the name passed through should be the indexed name, which contains an index representing which multivalued property is being referenced. See Property indexedName.

Parameters

nodeId - - the node Id

propertyName - - the name for the Property that contains the binary data.

Returns

InputStream - the binary data.

Throws

AuthenticationException - - if the user attempting the operation is not authenticated to perform it.

AuthorizationException - if the user does not have VIEW capabilities on the node. This exception will also be thrown if the user is not authorizated by the repository.

NoSuchPropertyException - - if the Property does not exist.

                 AuthorizationException,
                 RepositoryException

This method updates an existing node in a single transaction. The changed node attributes will be updated accordingly, including changed properties. This is a less granular way of performing similar actions like addNodeContent, moveNode, renameNode, and updateProperties. Additionally this provides access to modify a node's workflow status and workflow id. The node is assumed to be retrieved from this API and therefore properly formed when this call is made. Therefore if this method is called and some property values are not specified, those property values will be made null. The following node attributes cannot be modified via this API. created by, created date, modified by, modified date and path (modifying the parent will cause the node path to be updated properly). Please note that if the node is library services enabled, this method will not change any properties of the node. You need to use the VersionManager.save method to accomplish that.

Parameters

node - The node to update with the various changes set accordingly.

Returns

The updated node

Throws

AuthenticationException - - if the user attempting the operation is not authenticated to perform it.

AuthorizationException - - if the user does not have UPDATE capability on the node. This exception will also be thrown if the user is not authorizated by the repository.

RepositoryException - - for any other exception
