Class OverrideStubGenerator

java.lang.Object

org.ek9lang.compiler.fuzz.OverrideStubGenerator

final class OverrideStubGenerator
extends Object

Generates override method stubs for child classes derived from harvested parent methods. Produces 6 pattern variations: correct override, wrong return type, wrong param count, missing override keyword, narrowed access, and purity mismatch. Extracted from TemplateEnrichmentGenerator.

Method Summary

Modifier and Type	Method	Description
(package private) static String	addOverrideStubs(String body, List<HarvestedTemplate> templates, String parentName, Random random)	Adds override method stubs to the body of a child class.
(package private) static void	appendCorrectOverride(StringBuilder sb, HarvestedMethod method, String indent)	Case 0: Correct override with matching signature including parameters.
(package private) static void	appendMissingOverrideKeyword(StringBuilder sb, HarvestedMethod method, String indent)	Case 3: Missing 'override' keyword (just redeclare) — targets E05120.
(package private) static void	appendNarrowedAccessOverride(StringBuilder sb, HarvestedMethod method, String indent)	Case 4: Narrowed access (public to private) — targets E05130.
(package private) static void	appendPurityMismatchOverride(StringBuilder sb, HarvestedMethod method, String indent)	Case 5: Purity mismatch (non-pure overriding pure) — targets E05140/E05190.
(package private) static void	appendWrongParamCountOverride(StringBuilder sb, HarvestedMethod method, String indent)	Case 2: Wrong parameter count (extra parameter) — targets E05110.
(package private) static void	appendWrongReturnOverride(StringBuilder sb, HarvestedMethod method, String indent)	Case 1: Wrong return type — targets E05100.

Method Details

addOverrideStubs

static String addOverrideStubs(String body,
 List<HarvestedTemplate> templates,
 String parentName,
 Random random)

Adds override method stubs to the body of a child class. Picks 0-2 non-private, non-abstract parent methods and generates one of 6 override patterns for each.

Parameters:

body - the current class body text

templates - the harvested templates to search for parent methods

parentName - the name of the parent type

random - the random source

Returns:

the body with override stubs appended

appendCorrectOverride

static void appendCorrectOverride(StringBuilder sb,
 HarvestedMethod method,
 String indent)

Case 0: Correct override with matching signature including parameters.

appendWrongReturnOverride

static void appendWrongReturnOverride(StringBuilder sb,
 HarvestedMethod method,
 String indent)

Case 1: Wrong return type — targets E05100.

appendWrongParamCountOverride

static void appendWrongParamCountOverride(StringBuilder sb,
 HarvestedMethod method,
 String indent)

Case 2: Wrong parameter count (extra parameter) — targets E05110.

appendMissingOverrideKeyword

static void appendMissingOverrideKeyword(StringBuilder sb,
 HarvestedMethod method,
 String indent)

Case 3: Missing 'override' keyword (just redeclare) — targets E05120.

appendNarrowedAccessOverride

static void appendNarrowedAccessOverride(StringBuilder sb,
 HarvestedMethod method,
 String indent)

Case 4: Narrowed access (public to private) — targets E05130.

appendPurityMismatchOverride

static void appendPurityMismatchOverride(StringBuilder sb,
 HarvestedMethod method,
 String indent)

Case 5: Purity mismatch (non-pure overriding pure) — targets E05140/E05190.
