NodeData
class NodeData extends AbstractNodeData (View source)
The node data inside the content repository. This is only a data container that could be exchanged in the future.
NOTE: This is internal only and should not be used or extended by userland code.

Details
__construct(string $path, Workspace $workspace, string $identifier = null, array $dimensions = null)
Constructs this node data container
Creating new nodes by instantiating NodeData is not part of the public API! The content repository needs to properly integrate new nodes into the node tree and therefore you must use createNode() or createNodeFromTemplate() in a Node object which will internally create a NodeData object.
void
ensurePropertiesIsNeverNull()
Make sure the properties are always an array.
If the JSON in the DB is corrupted, decoding it can fail, leading to a null value. This may lead to errors later, when the value is used with functions that expect an array.
void
setProperty(string $propertyName, mixed $value)
Sets the specified property.
If the node has a content object attached, the property will be set there if it is settable.
protected
persistRelatedEntities(mixed $value)
Checks if a property value contains an entity and persists it.
bool
hasProperty(string $propertyName)
If this node has a property with the given name.
If the node has a content object attached, the property will be checked there.
mixed
getProperty(string $propertyName)
Returns the specified property.
If the node has a content object attached, the property will be fetched there if it is gettable.
void
removeProperty(string $propertyName)
Removes the specified property.
If the node has a content object attached, the property will not be removed on that object if it exists.
array
getProperties()
Returns all properties of this node.
If the node has a content object attached, the properties will be fetched there.
array
getPropertyNames()
Returns the names of all properties of this node.
void

Returns the absolute path of this node with additional context information (such as the workspace name).
Example: /sites/mysitecom/homepage/about@user-admin
int
getDepth()
Returns the level at which this node is located.
Counting starts with 0 for "/", 1 for "/foo", 2 for "/foo/bar" etc.
void
setWorkspace(Workspace $workspace = null)
Sets the workspace of this node.
string
getIdentifier()
Returns the identifier of this node.
This UUID is not the same as the technical persistence identifier used by Flow's persistence framework. It is an additional identifier which is unique within the same workspace and is used for tracking the same node in across workspaces.
It is okay and recommended to use this identifier for synchronisation purposes as it does not change even if all of the nodes content or its path changes.
void
setIndex(int $index)

int
getIndex()
Returns the index of this node which determines the order among siblings with the same parent node.

NOTE: This is only used for some very rare cases (to replace existing instances when moving).
protected NodeData[]
getChildNodeData()
Returns all direct child node data of this node data with reducing the result by dimensionHash only
Only used internally for setting the path of all child nodes.
int
getNumberOfChildNodes(string $nodeTypeFilter, Workspace $workspace, array $dimensions)

remove()
Removes this node and all its child nodes. This is an alias for setRemoved(true)
void
setRemoved(bool $removed)
Enables using the remove method when only setters are available
bool
isRemoved()
If this node is a removed node.
bool
isVisible()
Tells if this node is "visible".
For this the "hidden" flag and the "hiddenBeforeDateTime" and "hiddenAfterDateTime" dates are taken into account. The fact that a node is "visible" does not imply that it can / may be shown to the user. Further modifiers such as isAccessible() need to be evaluated.
bool
isAccessible()
Tells if this node may be accessed according to the current security context.
bool
hasAccessRestrictions()
Tells if a node, in general, has access restrictions, independent of the current security context.

No description
void
similarize(AbstractNodeData $sourceNode, bool $isCopy = false)
Make the node "similar" to the given source node. That means,

- node type
- content object will be set to the same values as in the source node.
array
getDimensionValues()
Returns the dimensions and their values.
protected void
buildDimensionValues()
Build a cached array of dimension values and a hash to search for it.
string
getDimensionsHash()
Get a unique string for all dimension values
Internal method
bool
matchesWorkspaceAndDimensions(Workspace $workspace, array $dimensions = null)
Checks if this instance matches the given workspace and dimensions.
bool
isInternal()
Check if this NodeData object is a purely internal technical object (like a shadow node).
An internal NodeData should never produce a Node object.
NodeData
move(string $targetPath, Workspace $targetWorkspace)
Move this NodeData to the given path and workspace.
Basically 4 scenarios have to be covered here, depending on:
- Does the NodeData have to be materialized (adapted to the workspace or target dimension)?
- Does a shadow node exist on the target path?
Because unique key constraints and Doctrine ORM don't support arbitrary removal and update combinations, existing NodeData instances are re-used and the metadata and content is swapped around.
protected NodeData|null
getExistingShadowNodeDataInExactWorkspace(string $path, Workspace $workspace, array $dimensionValues)
Find an existing shadow node data on the given path for the current node data of the node (used by setPath)
NodeData
createShadow(string $path)
Create a shadow NodeData at the given path with the same workspace and dimensions as this
Note: The constructor will already add the new object to the repository Internal method, do not use outside of the content repository.
protected void
setAsShadowOf(NodeData $nodeData = null)
This becomes a shdow of the given NodeData object.
If NULL or no argument is given then movedTo is nulled and removed is set to false effectively turning this into a normal NodeData.
protected NodeData
materializeToWorkspace(Workspace $workspace)
Materializes the original node data (of a different workspace) into the current workspace, excluding content dimensions
This is only used in setPath for now
protected void
calculatePathHash()
Calculates the hash corresponding to the path of this instance.
protected void
calculateParentPathHash()
Calculates the hash corresponding to the dimensions and their values for this instance.
void
__clone()
Create a fresh collection instance and clone dimensions
protected void
emitNodePathChanged(NodeData $nodeData)
Signals that a node has changed its path.
