PreProcessors

Processor subclasses that run before a third-party package is imported into the project. They prepare the import manifest by translating asset paths, detecting conflicts and changes, and determining item visibility.

Data Flow

Execution Order

PreProcessors run in this order (defined in ThirdPartyPackageProcessor):

1. PathProcessor — translates paths and determines what needs importing

2. PrepareProcessor — determines item visibility for the import dialog

PathProcessor	Non-project assets	DIRECTORIES, FILES, VARIABLES	Translates paths, detects conflicts and changes
