Class TypedParameterResolver<M>

java.lang.Object

io.fluxzero.common.handling.TypedParameterResolver<M>

Type Parameters:

M - the message or context type used for resolution (e.g. HasMessage, Object, etc.)

All Implemented Interfaces:

ParameterResolver<M>

Direct Known Subclasses:

CurrentUserParameterResolver, MetadataParameterResolver, UserParameterResolver

public abstract class TypedParameterResolver<M>
extends Object
implements ParameterResolver<M>

Abstract base class for ParameterResolvers that resolve parameters based on type matching.

This class provides a default matches(Parameter, Annotation, M) implementation that checks whether the expected type of the parameter is assignable from a configured base type.

Method Details

matches

public boolean matches(Parameter parameter,
 Annotation methodAnnotation,
 M value)

Determines whether the given parameter is eligible to be resolved by this resolver.

This default implementation matches if parameter.getType() is assignable from the configured base type.

Specified by:

matches in interface ParameterResolver<M>

Parameters:

parameter - the method parameter to resolve

methodAnnotation - the annotation on the method (if any)

value - the current message or context object

Returns:

true if this resolver can resolve the parameter

mayApply

public boolean mayApply(Executable method,
 Class<?> targetClass)

Determines whether this resolver may be applicable to the given method or constructor.

Specified by:

mayApply in interface ParameterResolver<M>

Parameters:

method - the handler method or constructor

targetClass - the declaring or target class

Returns:

true if this resolver could apply, false otherwise
