io.micronaut.inject.beans.AbstractInitializableBeanIntrospection<B>

Type Parameters:

B - The bean type

All Implemented Interfaces:

AnnotationMetadata, AnnotationMetadataDelegate, AnnotationMetadataProvider, AnnotationSource, BeanInfo<B>, BeanIntrospection<B>, UnsafeBeanInstantiationIntrospection<B>, Ordered, ArgumentCoercible<B>

Direct Known Subclasses:

AbstractInitializableBeanIntrospectionAndReference

public abstract class AbstractInitializableBeanIntrospection<B>
extends Object
implements UnsafeBeanInstantiationIntrospection<B>

Abstract implementation of the BeanIntrospection interface. This class is subclassed at compilation time by generated bytecode and should not be used directly.

The generated subclass uses method dispatch to access the bean instance. Boxed dispatch methods provide the general reflection-free access path, while the primitive dispatch methods exist for generated UnsafeBeanReadProperty and UnsafeBeanWriteProperty implementations that need to avoid primitive boxing in hot paths.

3.1

getTargetMethodByIndex

@Internal
protected abstract Method getTargetMethodByIndex(int index)

Find Method representation at the method by index. Used by MethodReference.getTargetMethod().

Returns:

The method

getAccessibleTargetMethodByIndex

protected final Method getAccessibleTargetMethodByIndex(int index)

Find Method representation at the method by index. Used by MethodReference.getTargetMethod().

Parameters:

index - The index

Returns:

The method

Since:

3.8.5

dispatch

protected <V> @Nullable V dispatch(int index,
 B target,
 @Nullable Object[] args)

Triggers the invocation of the method at index.

Type Parameters:

V - The result type

Parameters:

index - The method index

target - The target

args - The arguments

Returns:

The result

dispatchOne

protected <V> @Nullable V dispatchOne(int index,
 Object target,
 @Nullable Object arg)

Triggers the invocation of the method at index for a single-argument call, avoiding wrapping the value in an Object[] array.

For no-argument calls (for example, property getters), generated code passes null as arg. This is the boxed single-argument dispatch path used by unsafe bean property implementations. Primitive property access uses the type-specific dispatch methods below when generated introspections provide them, so serializers and other hot paths can avoid boxing primitive values.

Type Parameters:

V - The result type

Parameters:

index - The method index

target - The target

arg - The argument

Returns:

The result

dispatchOneVoid

protected void dispatchOneVoid(int index,
 Object target,
 @Nullable Object arg)

Triggers the invocation of the void method at index for a single argument call. Allowing to not wrap a single argument in an object array or return a placeholder value.

This method is used by setter paths where the caller does not need a return value. The primitive dispatchSet*Void methods below build on this contract and let generated introspections avoid both a synthetic return value and primitive boxing.

Parameters:

index - The method index

target - The target

arg - The argument
