Class CompositeNavPathRewriter

The composite-child transition-path rewrite algorithm, extracted out of UnityCompositeViewDefinitionEditor so the CustomEditor only drives the "what changed" detection while this class owns the "::"-path segment algebra. Lives beside CompositeNavWiring (which already centralizes the same separator/path conventions for the builder) rather than in Business/Ui: RewriteMenuTransitionSegment(string, string, string) is inherently editor tooling (it walks and mutates UnityEditor.SerializedObjects across the project via UnityEditor.AssetDatabase), so the class as a whole cannot be engine-agnostic even though its innermost helper, RewriteChildSegment(string, string, string, string), is pure string logic. Splitting just that one pure method into Business would separate the rule from the only code that exercises it, without giving any other consumer (runtime only walks paths via UnityMenuView.Actions; nothing else rewrites them) a reason to depend on it — so this stays extract-only, editor-side.

Syntax

public static class CompositeNavPathRewriter

Methods

RewriteChildSegment(string, string, string, string)

Returns value with each consecutive "compositeId::oldChildId" segment pair rewritten so the child becomes newChildId; returns null when the value contains no such pair (so callers can skip it).

Declaration

public static string RewriteChildSegment(string value, string compositeId, string oldChildId, string newChildId)

Parameters

Type	Name	Description
string	value	The transition value to inspect.
string	compositeId	The parent composite id to match.
string	oldChildId	The child id to match (immediately after the composite).
string	newChildId	The replacement child id.

Returns

Type	Description
string	The rewritten value, or null when unchanged.

RewriteMenuTransitionSegment(string, string, string)

Across all menu definition assets, rewrites every MENU_TRANSITION value whose transition path contains the consecutive segment pair "compositeId::oldChildId", replacing that child segment with newChildId. This keeps both direct ("composite::child") and full-path ("root::...::composite::child") targets in sync. Done over UnityEditor.SerializedObject (found by type name) so this editor needs no dependency on the menu module; changes register Undo and dirty the assets.

Declaration

public static void RewriteMenuTransitionSegment(string compositeId, string oldChildId, string newChildId)

Parameters

Type	Name	Description
string	compositeId	The composite whose child slot changed.
string	oldChildId	The previous child id.
string	newChildId	The new child id.

SyncNavTransitionsForChangedChildren(string, List<string>, List<string>)

When a child slot's hosted view was REPLACED (its id changed and the old id no longer appears anywhere in the composite), rewrites every menu's matching transition target "compositeId::oldChildId" to "compositeId::newChildId" so nav options follow the swap. Skips slot reorders (old id still present) and slot add/remove (different child count), which are ambiguous to auto-rewrite.

Declaration

public static void SyncNavTransitionsForChangedChildren(string compositeId, List<string> oldIds, List<string> newIds)

Parameters

Type	Name	Description
string	compositeId	The id of the edited composite.
List<string>	oldIds	Child ids before the edit.
List<string>	newIds	Child ids after the edit.
