◆ Remove()

Result<void> Remove ( Opt< ChangeList & > list = {} ) const

Removes the referenced g-node from this node system. Internally how the removal is done depends on the situation:

If the node is not defined by this node system, but inherited from a base, it is marked as removed in this node system, so effectively the inherited node is hidden.
If the node is defined by this node system, the node definition is removed. If this makes an inherited node visible, the latter is marked as removed as in the first case.

Not all g-nodes can be removed:

Input or output port lists can never be removed.
Top-level ports can only be removed if they belong to the root node. There are no restrictions on nested ports.
True nodes can only be removed if they are direct children of the root node.
Parameters

[in] list An optional ChangeList to track the changes.

◆ InheritChild()

Result<void> InheritChild	(	const InternedId &	childId,
		Opt< ChangeList & >	list = `{}`
	)		const

Removes any data for the child node #childId of the referenced node from the node system so that the state of the child node is restored to an unmodified instance of its base node. If there is no base, the node ceases to exist in the current node system. This function only has an effect if modifications to the child node have been made at the level of the node system of this reference.

Parameters

[in]	childId	The identifier of the child of this node which shall be restored to its inherited state.
[in]	list	An optional ChangeList to track the changes.

◆ InheritValue()

Result<Bool> InheritValue	(	const InternedId &	attr,
		Opt< ChangeList & >	list = `{}`
	)		const

Restores the inherited state of the value for #attr. This removes any value which has been set in this node system. It will also annul the effect of a previous invocation of RemoveValue().

Parameters

[in]	attr	The attribute whose value at this g-node shall be restored to the inherited state.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.

See also: RemoveValue

◆ RemoveValue()

Result<Bool> RemoveValue	(	const InternedId &	attr,
		Opt< ChangeList & >	list = `{}`
	)		const

Removes an attribute value from this g-node. The node won't have a value for #attr afterwards, i.e., even if one of its bases has a value for #attr, this node doesn't inherit the value. The removal can be undone by calling InheritValue().

Parameters

[in]	attr	The attribute whose value shall be removed from this g-node.
[in]	list	An optional ChangeList to track the changes.

Returns: True if modified.

See also: InheritValue

◆ SetValue() [1/5]

Result<Bool> SetValue	(	const InternedId &	attr,
		ForwardingDataPtr &&	value,
		Opt< ChangeList & >	list = `{}`
	)		const

Sets the value of #attr to value for this g-node. This will override any value which would otherwise be inherited for the attribute from a base.

Parameters

[in]	attr	The attribute whose value shall be set.
[in]	value	The new value for the attribute.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.

◆ SetValue() [2/5]

Result<Bool> SetValue	(	const ATTR &	attr,
		const typename ATTR::ValueType &	value,
		Opt< ChangeList & >	list = `{}`
	)		const

Sets the value of #attr to value for this g-node. This will override any value which would otherwise be inherited for the attribute from a base. Example:

MutablePort port;

port.SetValue(InheritNestedPorts, false) iferr_return;

iferr_return

#define iferr_return

Definition: resultbase.h:1519

Parameters

[in]	attr	The attribute whose value shall be set.
[in]	value	The new value for the attribute.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.

◆ SetValue() [3/5]

Result<Bool> SetValue	(	const ATTR &	attr,
		typename ATTR::ValueType &&	value,
		Opt< ChangeList & >	list = `{}`
	)		const

Sets the value of #attr to value for this g-node. This will override any value which would otherwise be inherited for the attribute from a base. Example:

MutablePort port;
TypeAccess ta;
port.SetValue(FixedPortType, std::move(ta)) iferr_return;

Parameters

[in]	attr	The attribute whose value shall be set.
[in]	value	The new value for the attribute, this will be moved into the g-node.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.

◆ SetValue() [4/5]

Result<Bool> SetValue	(	const typename ATTR::ValueType &	value,
		Opt< ChangeList & >	list = `{}`
	)		const

Sets the value of ATTR to value for this g-node. This will override any value which would otherwise be inherited for the attribute from a base. Example:

MutablePort port;

port.SetValue<decltype(InheritNestedPorts)>(false) iferr_return;

Template Parameters

ATTR	The attribute whose value shall be set.

Parameters

[in]	value	The new value for the attribute.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.

◆ SetValue() [5/5]

Result<Bool> SetValue	(	typename ATTR::ValueType &&	value,
		Opt< ChangeList & >	list = `{}`
	)		const

Sets the value of ATTR to value for this g-node. This will override any value which would otherwise be inherited for the attribute from a base. Example:

MutablePort port;
TypeAccess ta;
port.SetValue<decltype(FixedPortType)>(std::move(ta)) iferr_return;

Template Parameters

ATTR	The attribute whose value shall be set.

Parameters

[in]	value	The new value for the attribute, this will be moved into the g-node.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.

◆ ChangeValue()

Result<void> ChangeValue	(	const InternedId &	attr,
		const SubDataOperation &	op,
		const SubDataPathBlock &	path,
		ForwardingDataPtr &&	value,
		Opt< ChangeList & >	list = `{}`
	)		const

Sets a part of the value of #attr to value for this g-node.

Parameters

[in]	attr	The attribute whose value shall be set.
[in]	op	The SubDataOperation to use.
[in]	path	The path to the part of the attribute value which shall be changed.
[in]	value	The new value for the part.
[in]	list	An optional ChangeList to track the changes.

Returns: OK on success.
