CallSiteWriter (Groovy 6.0.0-beta-1)

org.codehaus.groovy.classgen.asm.CallSiteWriter

```
public class CallSiteWriter
extends Object
```
Bytecode writer for classic (non-invokedynamic) call sites.
Non-public API used by AsmClassGenerator. Do not use this class in application code. Groovy 6 defaults to invokedynamic (IndyCallSiteWriter); this writer is selected only when indy is disabled. The generated bytecode references org.codehaus.groovy.runtime.callsite.*, which lives in the optional groovy-callsite module — that module must be on the classpath both to emit and to execute such classes (WriterController fails fast if it is missing when indy is off).

    Sentinel name for constructor calls.
- Constructor Detail
  - public CallSiteWriter(WriterController wc)
    
    Creates a call site writer with the given controller.
    Parameters:
    wc - the writer controller
- Method Detail
  - public void fallbackAttributeOrPropertySite(PropertyExpression expression, Expression objectExpression, String name, MethodCallerMultiAdapter adapter)
    
    Generates a fallback call for attribute or property access.
    Parameters:
    expression - the property expression
    objectExpression - the object expression
    name - the property name
    adapter - the method caller adapter
  - public void generateCallSiteArray()
    
    Generates the call site array field and accessor methods.
  - public List<String> getCallSites()
    
    Returns the list of call site names.
    Returns:
    the call site names
  - public boolean hasCallSiteUse()
    
    Checks if any call sites have been used.
    Returns:
    true if call sites have been used
  - public void makeCallSite(Expression receiver, String message, Expression arguments, boolean safe, boolean implicitThis, boolean callCurrent, boolean callStatic)
    
    Generates a general method call through the call site infrastructure.
    Parameters:
    receiver - the receiver expression
    message - the method name
    arguments - the arguments expression
    safe - whether to use safe navigation
    implicitThis - whether the receiver is implicit 'this'
    callCurrent - whether to call on the current object
    callStatic - whether this is a static method call
  - public void makeCallSiteArrayInitializer()
    
    Generates bytecode to initialize the call site array field to null.
  - public void makeGetPropertySite(Expression receiver, String methodName, boolean safe, boolean implicitThis)
    
    Generates a general getProperty call.
    Parameters:
    receiver - the receiver expression
    methodName - the property name
    safe - whether to use safe navigation
    implicitThis - whether the receiver is implicit 'this'
  - public void makeGroovyObjectGetPropertySite(Expression receiver, String methodName, boolean safe, boolean implicitThis)
    
    Generates a GroovyObject getProperty call.
    Parameters:
    receiver - the receiver expression
    methodName - the property name
    safe - whether to use safe navigation
    implicitThis - whether the receiver is implicit 'this'
  - public void makeSetPropertySite(PropertyExpression expression, Expression objectExpression, String name, MethodCallerMultiAdapter adapter, boolean groovyObject)
    
    Emits a property-write site (GROOVY-12138). The assigned value is already on the operand stack. The default implementation is the classic ScriptBytecodeAdapter adapter call; the indy writer may override this to emit an invokedynamic setProperty call site.
    Parameters:
    expression - the property expression being assigned
    objectExpression - the receiver expression
    name - the property name
    adapter - the classic set adapter used for the default path
    groovyObject - whether the receiver is statically known to be a GroovyObject
  - public final void makeSingleArgumentCall(Expression receiver, String message, Expression arguments)
    
    Generates a single-argument method call.
    Parameters:
    receiver - the receiver expression
    message - the method name
    arguments - the argument expression
  - public void makeSingleArgumentCall(Expression receiver, String message, Expression arguments, boolean safe)
    
    Generates a single-argument method call with optional safe navigation.
    Parameters:
    receiver - the receiver expression
    message - the method name
    arguments - the argument expression
    safe - whether to use safe navigation
  - public void makeSiteEntry()
    
    Generates bytecode to load the call site array into a local variable.
  - public void prepareCallSite(String message)
    
    Prepares a call-site entry for the named method on the bytecode operand stack, loading the call-site array and selecting the slot for message.
    Parameters:
    message - the method name for which to prepare the call site
  - protected void prepareSiteAndReceiver(Expression receiver, String methodName, boolean implicitThis, boolean lhs)
    
    Generates bytecode to prepare the call site and receiver for a method call.
    Parameters:
    receiver - the receiver expression
    methodName - the method name
    implicitThis - whether the receiver is implicit 'this'
    lhs - whether this is on the left-hand side of an assignment
  - protected void visitBoxedArgument(Expression exp)
    
    Visits an argument expression and ensures it is boxed.
    Parameters:
    exp - the argument expression
