Constructor Details

InvokeDynamicWriter

public InvokeDynamicWriter(WriterController controller)

Creates an invocation writer that emits invokedynamic call sites.

Method Details

makeCachedCall

protected boolean makeCachedCall(Expression origin,
 ClassExpression sender,
 Expression receiver,
 Expression message,
 Expression arguments,
 MethodCallerMultiAdapter adapter,
 boolean safe,
 boolean spreadSafe,
 boolean implicitThis,
 boolean containsSpreadExpression)

Attempts to emit a call-site-cached invocation (or invokedynamic). Returns false if the call cannot be cached, causing the caller to fall through to the uncached path.

Overrides:

makeCachedCall in class InvocationWriter

Parameters:

origin - the original call expression

sender - the class from which the call is dispatched

receiver - the receiver expression

message - the method name expression

arguments - the arguments expression

adapter - the method caller adapter

safe - whether to use safe navigation

spreadSafe - whether to use spread-safe navigation

implicitThis - whether the receiver is implicit this

containsSpreadExpression - whether any argument uses spread

Returns:

true if a cached call was emitted

makeSingleArgumentCall

public void makeSingleArgumentCall(Expression receiver,
 String message,
 Expression arguments,
 boolean safe)

Generates a single-argument method call via the call-site writer.

Overrides:

makeSingleArgumentCall in class InvocationWriter

Parameters:

receiver - the receiver expression

message - the method name

arguments - the single argument expression

safe - whether to use safe navigation (?.)

writeGetProperty

protected void writeGetProperty(Expression receiver,
 String propertyName,
 boolean safe,
 boolean implicitThis,
 boolean groovyObject)

Emits an invokedynamic property-get call site with the given flags.

writeSetProperty

protected void writeSetProperty(Expression receiver,
 String propertyName,
 boolean implicitThis,
 boolean groovyObject)

Emits an invokedynamic property-write call site (GROOVY-12138). On entry, the assigned value sits on the operand stack (the assignment machinery evaluates the RHS before visiting the LHS). The value is boxed, the receiver pushed, and the two swapped so the call-site shape is receiver-first — (ReceiverType, ValueType)void — preserving the runtime invariant that arguments[0] is the receiver. The void return means no operand-stack result to clean up, matching the classic adapter path's accounting.

writeNormalConstructorCall

protected void writeNormalConstructorCall(ConstructorCallExpression call)

Emits a normal (non-direct, non-AIC) constructor call via the call-site writer.

Overrides:

writeNormalConstructorCall in class InvocationWriter

Parameters:

call - the constructor call expression to compile

coerce

public void coerce(ClassNode from,
 ClassNode target)

Emits a Groovy as coercion from from to target.

Overrides:

coerce in class InvocationWriter

Parameters:

from - the source type currently on the operand stack

target - the target type to coerce to

castToNonPrimitiveIfNecessary

public void castToNonPrimitiveIfNecessary(ClassNode sourceType,
 ClassNode targetType)

Converts sourceType to a non-primitive by using Groovy casting. sourceType might be a primitive This might be done using SBA#castToType

Overrides:

castToNonPrimitiveIfNecessary in class InvocationWriter

castNonPrimitiveToBool

public void castNonPrimitiveToBool(ClassNode sourceType)

Unboxes a non-primitive value on the operand stack to a primitive boolean.

Overrides:

castNonPrimitiveToBool in class InvocationWriter

Parameters:

sourceType - the type currently on top of the operand stack
