Functions

RegenerateEntityIds

func RegenerateEntityIds(desc *EntityDescription) map[engine.EntityId]engine.EntityId

RegenerateEntityIds replaces every non-empty entity id in desc and its children, returning the old-to-new id map for the duplicated subtree.

RegenerateEntityIdsAndRewriteReferences

func RegenerateEntityIdsAndRewriteReferences(desc *EntityDescription) map[engine.EntityId]engine.EntityId

RegenerateEntityIdsAndRewriteReferences regenerates subtree ids and rewrites EntityId fields that point at entities inside the same duplicated subtree.

RewriteEntityIdReferences

func RewriteEntityIdReferences(desc *EntityDescription, idMap map[engine.EntityId]engine.EntityId)

RewriteEntityIdReferences rewrites EntityId values in entity data bindings when their target appears in idMap. References outside idMap are left intact.

SetupEntityFromDescription

func SetupEntityFromDescription(e *engine.Entity, host *engine.Host, se *EntityDescription) (*engine.Entity, error)
