                    NoSuchObjectClassException

Create a Node in the repository. This operation will honor the DA capabilities set on the parent node. For example, if the user does not have CREATE capabilities on the parent node, the operation might fail.

Parameters

context - The ContentContext Object

type - The type of node - can be Node.HIERARCHY or Node.CONTENT

parentPath - The path to the parent of the new node to create.

newNodeName - The name of the node

Returns

The newly created node.

Throws

RepositoryException

NodeExistsException

AuthorizationException

NoSuchObjectClassException

addNode

Node addNode(ContentContext context,
             int type,

                    NodeExistsException,
                    NoSuchObjectClassException

Create a Node in the repository. This operation will honor the DA capabilities set on the parent node. For example, if the user does not have CREATE capabilities on the parent node, the operation might fail. If the repository is a managed repository, it will also check out the node for the user.

Parameters

context - The ContentContext Object

type - The type of node - can be Node.HIERARCHY or Node.CONTENT

parentPath - The path to the parent of the new node to create.

newNodeName - The name of the node

objectClassName - The object class name to be associated with the node.

properties - The properties of the node.

Returns

The newly created node. The returned VirtualNode will have all the objectClass information and the properties of the node in the getCurrentVersion() method - irrespective of whether the node is for a managed repository or not.

Throws

RepositoryException

AuthorizationException

NodeExistsException

NoSuchObjectClassException

getNodeByUUID

Node getNodeByUUID(ContentContext context,
                   ID nodeId)
                   throws RepositoryException,

                          AuthenticationException,
                          NoSuchNodeException

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 #getPropertyBytes} is necessary.

The Node Cache will be checked first before going to the spi to retrieve the Node.

Before retrieving the node it will see if the node has BROWSE & the VIEW capability on it. If either one of them is not set, it'll 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

RepositoryException

AuthorizationException

AuthenticationException

NoSuchNodeException

                    NoSuchNodeException

Get a node by path. throws RepositoryException, AuthorizationException if node does not have VIEW / BROWSE capabilities.

Parameters

context - The content context object

path -

Returns

The virtual node

Throws

RepositoryException

AuthorizationException

NoSuchNodeException

Gets 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

AuthorizationException - if the user does not have VIEW capabilities on the node.

NoSuchPropertyException - - if the Property does not exist.

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 lifecycle status and lifecycle 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

AuthorizationException

RepositoryException
