Method Details

getTargetClass

public Class<?> getTargetClass()

Description copied from interface: HandlerInvoker

The target class that contains the handler method.

Specified by:

getTargetClass in interface HandlerDescriptor

Specified by:

getTargetClass in interface HandlerInvoker

Returns:

the declaring class of the handler

getMethod

public Executable getMethod()

Description copied from interface: HandlerInvoker

The Executable representing the handler method (can be a static or instance Method or Constructor).

Specified by:

getMethod in interface HandlerDescriptor

Specified by:

getMethod in interface HandlerInvoker

Returns:

the executable method

getMethodAnnotation

public <A extends Annotation> A getMethodAnnotation()

Description copied from interface: HandlerInvoker

Retrieves a specific annotation from the handler method, if present.

Specified by:

getMethodAnnotation in interface HandlerDescriptor

Specified by:

getMethodAnnotation in interface HandlerInvoker

Type Parameters:

A - the annotation type

Returns:

the annotation instance, or null if not found

expectResult

public boolean expectResult()

Description copied from interface: HandlerInvoker

Indicates whether the handler method has a return value.

This is based on the method's signature: if it returns void, this returns false; otherwise, it returns true.

Specified by:

expectResult in interface HandlerDescriptor

Specified by:

expectResult in interface HandlerInvoker

Returns:

true if the method returns a value; false if it is void

isPassive

public boolean isPassive()

Description copied from interface: HandlerInvoker

Indicates whether this handler operates in passive mode (i.e., results will not be published).

Specified by:

isPassive in interface HandlerDescriptor

Specified by:

isPassive in interface HandlerInvoker

Returns:

true if passive; otherwise false

invoke

public Object invoke(BiFunction<Object,Object,Object> combiner)

Description copied from interface: HandlerInvoker

Invokes the handler and combines results using the given combiner function. Used when aggregating results from multiple invokers (e.g. HandlerInvoker.join(List)).

Specified by:

invoke in interface HandlerInvoker

Parameters:

combiner - function to combine multiple results

Returns:

the combined result
