org.codehaus.groovy.classgen.asm.sc.StaticTypesWriterController

public class StaticTypesWriterController
extends DelegatingController

An alternative WriterController which handles static types and method dispatch. In case of a "mixed mode" where only some methods are annotated with TypeChecked then this writer will delegate to the classic writer controller.

Method Details

init

public void init(AsmClassGenerator asmClassGenerator,
 GeneratorContext gcon,
 org.objectweb.asm.ClassVisitor cv,
 ClassNode cn)

Description copied from class: WriterController

Initializes this controller with compilation context and ASM infrastructure. Must be called exactly once before any bytecode generation operations. Sets up all supporting writers (call site, closure, lambda, etc.) and configures optimization strategies based on compiler configuration.

Overrides:

init in class DelegatingController

Parameters:

asmClassGenerator - the class generator managing the overall compilation

gcon - the compilation context tracking state across the compilation unit

cv - the ASM ClassVisitor for emitting bytecode directives

cn - the ClassNode being compiled

setMethodNode

public void setMethodNode(MethodNode mn)

Description copied from class: WriterController

Sets the MethodNode for the method currently being compiled. Automatically clears any active constructor node, since only one can be active. Used during compilation to track which method's bytecode is being generated.

Overrides:

setMethodNode in class DelegatingController

Parameters:

mn - the MethodNode to compile, or null to deactivate

setConstructorNode

public void setConstructorNode(ConstructorNode cn)

Description copied from class: WriterController

Sets the ConstructorNode for the constructor currently being compiled. Automatically clears any active method node, since only one can be active. Used during compilation to track which constructor's bytecode is being generated.

Overrides:

setConstructorNode in class DelegatingController

Parameters:

cn - the ConstructorNode to compile, or null to deactivate

methodHasDynamicResolution

public boolean methodHasDynamicResolution()

GROOVY-11968: returns true when the current statically compiled method contains one or more sub-expressions that will be routed through the regular (non-static) call site writer via getCallSiteWriterFor(org.codehaus.groovy.ast.expr.Expression). The regular writer's per-method state must then be initialized at method entry.

Since:

6.0.0

isFastPath

public boolean isFastPath()

Description copied from class: WriterController

Returns true if the compiler is currently in fast-path mode, emitting specialized bytecode for primitive type operations. Use this to determine whether expression helpers should apply optimizations.

Overrides:

isFastPath in class DelegatingController

Returns:

true if fast-path compilation mode is active

getCallSiteWriter

public CallSiteWriter getCallSiteWriter()

Description copied from class: WriterController

Returns the CallSiteWriter responsible for generating dynamic call site infrastructure. Behavior depends on bytecode strategy: either invokedynamic for modern JVMs or traditional call-site caching for broader compatibility.

Overrides:

getCallSiteWriter in class DelegatingController

getCallSiteWriterFor

public CallSiteWriter getCallSiteWriterFor(Expression expression)

Description copied from class: WriterController

Returns the CallSiteWriter for a specific expression. Currently delegates to the default CallSiteWriter; reserved for future expression-specific optimization strategies.

Overrides:

getCallSiteWriterFor in class DelegatingController

Parameters:

expression - the expression being processed

Returns:

the appropriate call site writer for this expression

getRegularCallSiteWriter

public CallSiteWriter getRegularCallSiteWriter()

getStatementWriter

public StatementWriter getStatementWriter()

Description copied from class: WriterController

Returns the StatementWriter for compiling Groovy statements into bytecode. Selection depends on optimization mode: OptimizingStatementWriter for WriterController.optimizeForInt, otherwise generic StatementWriter.

Overrides:

getStatementWriter in class DelegatingController

getTypeChooser

public TypeChooser getTypeChooser()

Description copied from class: WriterController

Returns the TypeChooser used to select appropriate type representations for expressions during compilation, supporting both dynamic and typed paths.

Overrides:

getTypeChooser in class DelegatingController

getInvocationWriter

public InvocationWriter getInvocationWriter()

Description copied from class: WriterController

Returns the InvocationWriter for compiling method calls and dynamic function invocations into appropriate bytecode patterns.

Overrides:

getInvocationWriter in class DelegatingController

getRegularInvocationWriter

public InvocationWriter getRegularInvocationWriter()

getBinaryExpressionHelper

public BinaryExpressionHelper getBinaryExpressionHelper()

Description copied from class: WriterController

Returns the appropriate BinaryExpressionHelper for the current code path. Selects fast-path specialized handling when WriterController.isFastPath() is true, otherwise delegates to the general-purpose binary expression handler. Fast-path optimization is controlled by WriterController.optimizeForInt.

Overrides:

getBinaryExpressionHelper in class DelegatingController

Returns:

the binary expression writer for the active compilation mode

getMethodReferenceExpressionWriter

public MethodReferenceExpressionWriter getMethodReferenceExpressionWriter()

Description copied from class: WriterController

Returns the MethodReferenceExpressionWriter for compiling method reference expressions compatible with Java functional interface targets.

Overrides:

getMethodReferenceExpressionWriter in class DelegatingController

getUnaryExpressionHelper

public UnaryExpressionHelper getUnaryExpressionHelper()

Description copied from class: WriterController

Returns the appropriate UnaryExpressionHelper for the current code path. Selects fast-path specialized handling when WriterController.isFastPath() is true, otherwise delegates to the general-purpose unary expression handler. Fast-path optimization is controlled by WriterController.optimizeForInt.

Overrides:

getUnaryExpressionHelper in class DelegatingController

Returns:

the unary expression writer for the active compilation mode

getClosureWriter

public ClosureWriter getClosureWriter()

Description copied from class: WriterController

Returns the ClosureWriter for compiling Groovy closure literals into inner classes implementing GroovyObject and supporting variable capture.

Overrides:

getClosureWriter in class DelegatingController
