The '''ParentReferenceLink<T>''' component [[drives]] a [[field]] depending on the value of a compatible [[Component:ParentReference|ParentReference]] as part of a [[parent value]] system.
== Fields ==
{{Table ComponentFields
{{Table ComponentFields
|MatchTag|String|
|MatchTag|String|The tag to search for on the slot's immediate parent. Compatible [[Component:ParentReference|ParentReference]] components must have the same <code>Tag</code>.
|Target|{{RootFieldType|RefDrive`1|T}}|TypeAdv1=true|The field to drive using the value of the linked parent.
|WriteBack|Bool|
|WriteBack|Bool|If <code>True</code>, any writes to the driven field will be propagated back to the <code>Reference</code> provided by the ParentReference.
|DefaultReference|'''T'''|TypeAdv3=true|
|DefaultReference|'''T'''|TypeAdv3=true|Default value to use if the component can not find a compatible ParentReference.

== Behavior ==
== Usage ==
Upon a change of parent, this component will search for ParentReference components on the slot's immediate parent that have a matching type and tag. If it can find such a component and link to it, it will drive the <code>Target</code> field based on the <code>Reference</code> of the ParentReference. If it can not find such a component, it will use the <code>DefaultReference</code> value.
If True, any writes to the driven field will be propagated back to the Reference provided by the ParentReference.
DefaultReference
T
Default value to use if the component can not find a compatible ParentReference.
Usage
Upon a change of parent, this component will search for ParentReference components on the slot's immediate parent that have a matching type and tag. If it can find such a component and link to it, it will drive the Target field based on the Reference of the ParentReference. If it can not find such a component, it will use the DefaultReference value.
