Connect()

Result<void> Connect	(	Result< MutablePort > &&	target,
		Wires	modes = WIRE_MODE::CONNECT_DEFAULT,
		Opt< ChangeList & >	list = {}
	)		const

Connects this port to the other port #target using the given wire #modes. Usually you use one of the values WIRE_MODE::MIN, WIRE_MODE::NORMAL, WIRE_MODE::MAX for #modes, then a connection with a value wire of the given priority is created from this port to the #target port. But you can also add dependency and event wires by using an appropriate Wires value for #modes. And for each wire you can specify one of the special wire modes:

• WIRE_MODE::NONE doesn't change the current wire mode.
• WIRE_MODE::REMOVE removes the wire. If necessary, this hides inherited wires.
• WIRE_MODE::INHERIT inherits the wire from a base node system.

Typically, you connect an output port of a root child node to an input port of another root child node. But you can also connect

• an output port of a root child node to an output port of the root node (to forward the output of the child node to the root node)
• an input port of the root node to an input port of a root child node, (to forward the input of the root node to the child node)
• an input port of the root node to an output port of the same root node (to forward the input directly to the output without changing anything).

It is not possible to connect ports which don't belong to the root node or its direct children.

It is not allowed to create a cycle in the graph. However the Connect function itself doesn't check this, it is done later during e.g. MutableRoot::Validate or MutableRoot::EndModification. Therefore it is possible to temporarily introduce a cycle and resolve this immediately afterwards by removing another connection.

Parameters

[in]	target	The target port to connect to. Result<MutablePort> is accepted and the error, if any, is forwarded.
[in]	modes	The Wires to use for the connection.
[in]	list	An optional ChangeList to track the changes.

Returns

OK on success.

SetDefaultValue()

Result<void> SetDefaultValue

(

T &&

value

)

const

Sets the value of the DefaultValue attribute to value for this port. This will override any values which would otherwise be inherited from a base port.

Parameters

[in]

value

The value for the DefaultValue attribute.

Returns

OK on success.

SetType() [1/2]

Result<void> SetType

(

const DataType &

dataType

)

const

Sets the given #dataType as the value of the FixedPortType attribute.

Parameters

[in]

dataType

The data type for this port.

Returns

OK on success.

SetType() [2/2]

Result<void> SetType

(

)

const

Sets the type T as the value of the FixedPortType attribute.

Template Parameters

T	The data type for this port.

Returns

OK on success.

SetConnectionValue() [1/3]

Result<Bool> SetConnectionValue	(	const MutablePort &	target,
		CONNECTION_POSITION	position,
		const InternedId &	attr,
		ForwardingDataPtr &&	value,
		Opt< ChangeList & >	list = {}
	)		const

Sets the value of #attr to value for the connection from this port to #target. This will override any previously existing value.

Parameters

[in]	target	The other end of the connection.
[in]	position	The connection position at which the attribute's value shall be set.
[in]	attr	The attribute whose value shall be set.
[in]	value	The value for the attribute.

Returns

True if the value has been changed.

SetConnectionValue() [2/3]

Result<Bool> SetConnectionValue	(	const MutablePort &	target,
		CONNECTION_POSITION	position,
		const ATTR &	attr,
		const typename ATTR::ValueType &	value,
		Opt< ChangeList & >	list = {}
	)		const

Sets the value of #attr to value for this node. This will override any previously existing value.

Parameters

[in]	attr	The attribute whose value shall be set.
[in]	target	The other end of the connection.
[in]	position	The connection position at which the attribute's value shall be set.
[in]	value	The value for the attribute.

Returns

True if the value has been changed.

SetConnectionValue() [3/3]

Result<Bool> SetConnectionValue	(	const MutablePort &	target,
		CONNECTION_POSITION	position,
		const ATTR &	attr,
		typename ATTR::ValueType &&	value,
		Opt< ChangeList & >	list = {}
	)		const

Sets the value of #attr to value for this node. This will override any previously existing value.

Parameters

[in]	attr	The attribute whose value shall be set.
[in]	target	The other end of the connection.
[in]	position	The connection position at which the attribute's value shall be set.
[in]	value	The value for the attribute.

Returns

True if the value has been changed.
