Detailed Description

MutableGNode is the base class of mutable node references. The class hierarchy is

GNodeBase
- MutableGNode
  - MutableNode
    - MutableRoot
  - MutablePortList
    - MutablePort

See also usernodes_nodes for a class diagram and more details. The function NodeSystem::BeginModification() returns a reference to the root node of a node system with write access, from this all other nodes and ports can be found and modified.

Constructor & Destructor Documentation

◆ MutableGNode() [1/3]

MutableGNode ( )

default

Constructs a null node reference.

◆ MutableGNode() [2/3]

MutableGNode	(	NodeSystemInterface *	system,
		const GNodeHandle &	node
	)

private

◆ MutableGNode() [3/3]

MutableGNode	(	NodeSystemInterface *	system,
		GNodeHandle &&	node
	)

private

Member Function Documentation

◆ Reset()

void Reset ( )

Resets this @CLASS to the state it has right after default construction. This includes freeing all resources held by this @CLASS.

◆ operator=()

MutableGNode& operator= ( std::nullptr_t )

Resets this reference to a null reference.

◆ InitFromPath() [1/2]

Result<void> InitFromPath	(	NodeSystemInterface *	system,
		const NodePath &	path,
		NODE_KIND	check = `NODE_KIND::ALL_MASK`
	)

Initializes a g-node reference from a node system and a path. If there's no node in the node system for the given path, this reference is set to a null reference. If a node exists but its kind doesn't match the check mask, an IllegalArgumentError is returned.

Parameters

[in]	system	The node system to use.
[in]	path	A path which points to a g-node in the given node system.
[in]	check	A mask of the expected node kind(s).

Returns: Usually OK (even when path doesn't exist), but an IllegalArgumentError if path exists but doesn't match check.

◆ InitFromPath() [2/2]

Result<void> InitFromPath	(	NodeSystemInterface *	system,
		const PathBlock &	path,
		NODE_KIND	check = `NODE_KIND::ALL_MASK`
	)
