org.apache.groovy.ast.tools.CopyWithUtils

public final class CopyWithUtils
extends Object

Shared AST-generation glue for nested-path copyWith, used by both the @Immutable and @RecordType transforms so the generated code (and its evolution) stays identical across the two.

Since:

6.0.0

Method Summary

Modifier and Type	Method	Description
static void	addCopyWithBlockMethod(ClassNode cNode)	The transactional block overload: copyWith { name = 'x'; address.city = 'y' }.
static void	addCopyWithIdentityMethod(ClassNode cNode)	Backward-compatibility shim: a no-arg copyWith() with its historical semantics (no changes → the same instance).
static Statement	nestedFlattenStmt(String mapParamName)	The leading statement of a nested-aware copyWith(Map): <mapParamName> = NestedCopyWithSupport.flatten(this, <mapParamName>).

Method Details

nestedFlattenStmt

public static Statement nestedFlattenStmt(String mapParamName)

The leading statement of a nested-aware copyWith(Map): <mapParamName> = NestedCopyWithSupport.flatten(this, <mapParamName>). Plain keys pass through unchanged, so flat usage is unaffected.

addCopyWithIdentityMethod

public static void addCopyWithIdentityMethod(ClassNode cNode)

Backward-compatibility shim: a no-arg copyWith() with its historical semantics (no changes → the same instance). Needed once a copyWith(Closure) overload exists, otherwise the historically supported zero-arg call becomes ambiguous.

addCopyWithBlockMethod

public static void addCopyWithBlockMethod(ClassNode cNode)

The transactional block overload: copyWith { name = 'x'; address.city = 'y' }.
