Detailed Description

The basic scene graph node interface.

Any class that is supposed to be part of a scene graph hierarchy must implement this interface.

See SetId() for a description of valid node IDs.
See Graph::INamespace for details about the hierarchical organization of node IDs.

◆ DeserializeNode()

virtual Bool Murl::Graph::INode::DeserializeNode ( IDeserializeAttributeTracker tracker)

pure virtual

Set the node ID.

A node may have an optional ID, by which it can later be referenced from another node in the scene graph, or from a Logic::IProcessor to directly manipulate the node's properties from code. A valid node ID can only contain underscores ('_'), digits ('0'..'9') and/or alphabetic characters ('a'..'z' and 'A'..'Z'), and must not begin with a digit. In addition, node IDs must be unique within a common namespace.
See Graph::INamespace for examples of how to refer to individual nodes by their ID.

Parameters
idThe node ID to set.
Returns
true if successful.

◆ GetId()

◆ GetPath()

virtual String Murl::Graph::INode::GetPath ( ) const
pure virtual

Calculate the absolute path to the node.

Returns
The node path.

◆ IsPrivate()

virtual Bool Murl::Graph::INode::IsPrivate ( ) const
pure virtual

Check if this node is considered private.

If a node is marked private, it is not possible to reference that node or any of its children from outside the sub-graph beneath that node.

Returns
true if private.

◆ SetHead()

virtual Bool Murl::Graph::INode::SetHead ( Bool  isHead)
pure virtual

Define whether this node represents the head of a sub-graph.

When a sub-graph is created and added as a child of an existing scene graph node, this method must be called on the sub-graph's top node with isHead set to true. This must be done in order to detect any sub-graphs that were not correctly detached and destroyed before their respective parent graph is destroyed. Failing to do so may result in memory leaks or invalid node pointers.

Parameters
isHeadIf true, the node is set to be a head node.
Returns
true if successful.

◆ IsHead()

virtual Bool Murl::Graph::INode::IsHead ( ) const
pure virtual

Check whether this node represents the head of a sub-graph.

Returns
true if the node is a head node.

◆ SetLocked()

virtual Bool Murl::Graph::INode::SetLocked ( Bool  isLocked)
pure virtual

Lock/unlock the node.

Creating and destroying sub-graphs is usually an asynchronous task that is carried out in multiple stages. To prevent interference with regular graph traversals, it is necessary to have a sub-graph locked whenever it being initialized or de-initialized while it is linked to another scene graph node. Therefore, this method must be called with isLocked set to true prior to inserting it into the scene graph or prior to de-initializing it. The sub-graph may only be safely unlocked after it has been fully initialized, or detached from its parent.

Parameters
isLockedIf true, the node gets locked for regular traversals.
Returns
true if successful.

◆ IsLocked()

virtual Bool Murl::Graph::INode::IsLocked ( ) const
pure virtual

Check if this node is locked for regular traversals.

See SetLocked().

Returns
true if locked.

◆ SetSwapped()

virtual Bool Murl::Graph::INode::SetSwapped ( Bool  isSwapped)
pure virtual

Set/clear the node's initial swap state.

The node's swapped state is used as a hint to the engine, so that the node may decide to delay creation of any internal objects until they are actually used. This is usually the case for e.g. textures, which consume a large amount of video memory. Here, setting the node's swapped state results in not creating the video memory resources until the texture is referenced for the first time. By default, the swapped state is disabled. Note that this property can only be set before the node is initialized, after that the method returns false.

Parameters
isSwappedThe swap state of the node.
Returns
true if successful.

◆ IsSwapped()

virtual Bool Murl::Graph::INode::IsSwapped ( ) const
pure virtual

Check if this node is initially in the swapped state.

See SetSwapped().

Returns
true if in the swapped state.

◆ SetAutomaticSwappingEnabled()

virtual Bool Murl::Graph::INode::SetAutomaticSwappingEnabled ( Bool  enabled)
pure virtual

Enable/disable auto-swapping for this node.

When enabled, the engine may decide to swap-out any node-specific resources when they have not been used during the last frame. Like the initial swap state set via SetSwapped(), this is only a hint and applies to certain nodes only, such as textures. By default, this feature is disabled. Note also that auto-swapping can only be set before the node is initialized. When auto-swapping is enabled, it is usually a good idea to also set the initial swap state to true (via SetSwapped()), as otherwise the node's resources are created at initialization and possibly immediately swapped out when the node is not being used in the following frame.

Parameters
enabledIf true, auto swapping is enabled.
Returns
true if successful.

◆ IsAutomaticSwappingEnabled()

virtual Bool Murl::Graph::INode::IsAutomaticSwappingEnabled ( ) const
pure virtual

Check if auto-swapping is enabled for this node.

See SetSwappable().

Returns
true if enabled.

◆ SetManualSwappingEnabled()

virtual Bool Murl::Graph::INode::SetManualSwappingEnabled ( Bool  enabled)
pure virtual

Enable/disable manual swapping for this node.

When enabled, the user can trigger a swap-out of any node-specific resources when they have not been used during the last frame, by calling the TriggerSwapping() method on the Graph::IRoot object that can be accessed e.g. via the Logic::IState object. See SetAutomaticSwappingEnabled().

Parameters
enabledIf true, manual swapping is enabled.
Returns
true if successful.

◆ IsManualSwappingEnabled()

pure virtual

See SetManualSwappingEnabled().

Returns

Returns
true if pending.

◆ SetBoundingVolumeModified()

virtual Bool Murl::Graph::INode::SetBoundingVolumeModified ( Bool  isModified)
pure virtual

Set/reset the "bounding volume modified" state of the node.

The "bounding volume modified" state signals that there was some modification of one or more of the nodes within this node's sub-graph which affects this node's overall bounding volume. If isModified is true, the change is propagated to all of the node's parents, whereas a value of false clears this state in all of the node's child sub-graphs. This propagation is only done when the node is not locked. See SetModifiedFlags() and ClearModifiedFlags(), together with NODE_FLAG_IS_BOUNDING_VOLUME_MODIFIED.

Parameters
isModifiedIf true, the bounding volume is flagged as modified.
Returns
true if successful.

true if successful.

◆ ClearModifiedFlags()

◆ AddReference()

virtual Bool Murl::Graph::INode::AddReference ( )
pure virtual

Increment the node's internal reference counter by 1.

Whenever a node is persistently referenced from a different location in the application, this method must be called to indicate that it must not be destroyed, to prevent existing pointers to become invalid. Using a Graph::IReference node automatically performs this task together with its counterpart RemoveReference(), as do the individual Logic::GraphNodeT helpers. If a node is directly referenced from user code, it is up to the user to correctly increment/decrement the node's reference counter. A sub-graph can only be correctly destroyed when all of its children have a reference counter of 0.

Returns
true if successful.
