Responsibility

Provides the KSP implementation for @NavParam. It discovers annotated classes and generates Kotlin source files containing string constants for navigation argument class names.

Design Patterns

  • KSP provider and processor entry points.
  • Dedicated code generator behind the ICodeGenerator interface.
  • KotlinPoet file construction for generated Kotlin objects.

Data & Control Flow

KSP creates NavParamProcessorProvider, which builds NavParamProcessor with the environment logger and code generator. Each round resolves @NavParam class declarations, groups them by parent declaration, and passes each group to NavParamCodeGenerator. The generator writes a ParentParam.kt file for each parent class group.

Integration Points

  • Depends on :annotation, KSP API, and KotlinPoet.
  • Registered through the KSP plugin in build.gradle.kts.
  • Meaningful package maps live under src/main/kotlin/co/anitrend/arch/processor.
