Interface DirectedCodegen<C extends CodegenContext<S,?,I>,S,I extends SmithyIntegration<S,?,C>>

Type Parameters:
C - Smithy CodegenContext to use in directed methods.
S - Settings object passed to directed methods as part of the context.
I - SmithyIntegration type to use in directed methods.
public interface DirectedCodegen<C extends CodegenContext<S,?,I>,S,I extends SmithyIntegration<S,?,C>>
Provides a directed code generation abstraction to make it easier to implement a Smithy code generator for a single service that leverages other abstractions in smithy-codegen-core, including SmithyIntegration, SymbolProvider, CodegenContext, SymbolWriter, and WriterDelegator.

  • Method Details

    • createSymbolProvider

      SymbolProvider createSymbolProvider(CreateSymbolProviderDirective<S> directive)
      Create the SymbolProvider used to map shapes to code symbols.
      Parameters:
      directive - Directive context data.
      Returns:
      Returns the created SymbolProvider.

    • createContext

      C createContext(CreateContextDirective<S,I> directive)
      Creates the codegen context object.
      Parameters:
      directive - Directive context data.
      Returns:
      Returns the created context object used by the rest of the directed generation.

    • generateService

      void generateService(GenerateServiceDirective<C,S> directive)
      Generates the code needed for a service shape.
      Parameters:
      directive - Directive to perform.

    • generateResource

      default void generateResource(GenerateResourceDirective<C,S> directive)
      Generates the code needed for a resource shape.
      Parameters:
      directive - Directive to perform.

    • generateOperation

      default void generateOperation(GenerateOperationDirective<C,S> directive)
      Generates the code needed for an operation shape.
      Parameters:
      directive - Directive to perform.

    • generateStructure

      void generateStructure(GenerateStructureDirective<C,S> directive)
      Generates the code needed for a structure shape.

      This method should not be invoked for structures marked with the error trait.

      Parameters:
      directive - Directive to perform.

    • generateError

      void generateError(GenerateErrorDirective<C,S> directive)
      Generates the code needed for an error structure.
      Parameters:
      directive - Directive to perform.

    • generateUnion

      void generateUnion(GenerateUnionDirective<C,S> directive)
      Generates the code needed for a union shape.
      Parameters:
      directive - Directive to perform.

    • generateEnumShape

      void generateEnumShape(GenerateEnumDirective<C,S> directive)
      Generates the code needed for an enum shape, whether it's a string shape marked with the enum trait, or a proper enum shape introduced in Smithy IDL 2.0.
      Parameters:
      directive - Directive to perform.

    • generateIntEnumShape

      void generateIntEnumShape(GenerateIntEnumDirective<C,S> directive)
      Generates the code needed for an intEnum shape.
      Parameters:
      directive - Directive to perform.

    • customizeBeforeShapeGeneration

      default void customizeBeforeShapeGeneration(CustomizeDirective<C,S> directive)
      Performs any necessary code generation before all shapes are generated, using the created codegen context object.
      Parameters:
      directive - Directive to perform.

    • customizeBeforeIntegrations

      default void customizeBeforeIntegrations(CustomizeDirective<C,S> directive)
      Performs any necessary code generation after all shapes are generated, using the created codegen context object before integrations perform customizations.
      Parameters:
      directive - Directive to perform.

    • customizeAfterIntegrations

      default void customizeAfterIntegrations(CustomizeDirective<C,S> directive)
      Performs any necessary code generation after all shapes are generated, using the created codegen context object after all integrations have performed customizations.

      This method should be used to do things like:

      • Flush any code writers created by your WriterDelegator.
      • Generate dependency manifests (e.g., poms) from WriterDelegator.
      • Perform any remaining codegen tasks like formatting or validating the generated output.
      Parameters:
      directive - Directive to perform.
