Method Details
-
getKind
- Specified by:
getKind
in interfaceInvocationContext<T,
T> - Returns:
- An enum representing the kind of interception that is occurring.
-
getTarget
- Specified by:
getTarget
in interfaceInvocationContext<T,
T> - Returns:
- The target object
-
proceed
Description copied from interface:InvocationContext
Proceeds with the invocation. If this is the last interceptor in the chain then the final implementation method is invoked- Specified by:
proceed
in interfaceConstructorInvocationContext<T>
- Specified by:
proceed
in interfaceInvocationContext<T,
T> - Returns:
- The return value of the method
- Throws:
RuntimeException
- chain may throw RTE
-
getArguments
Description copied from interface:Executable
The required argument types.- Specified by:
getArguments
in interfaceExecutable<T,
T> - Returns:
- The arguments
-
invoke
Description copied from interface:Executable
Invokes the method.- Specified by:
invoke
in interfaceExecutable<T,
T> - Parameters:
instance
- The instance. Nullable only if it's a static method call.arguments
- The arguments- Returns:
- The result
-
getConstructor
- Specified by:
getConstructor
in interfaceConstructorInvocationContext<T>
- Returns:
- The bean type.

T1
- The bean type- Parameters:
resolutionContext
- The resolution contextbeanContext
- The bean contextinterceptors
- The interceptors. Can be null and if so should be resolved from the context.definition
- The definitionconstructor
- The bean constructorparameters
- The resolved parameters- Returns:
- The instantiated bean
- Since:

@Internal @NonNull public static <T1> T1 instantiate(@NonNull @NonNull BeanResolutionContext resolutionContext, @NonNull @NonNull BeanContext beanContext, @Nullable @Nullable List<BeanRegistration<Interceptor<T1, T1>>> interceptors, @NonNull @NonNull BeanDefinition<T1> definition, @NonNull @NonNull BeanConstructor<T1> constructor, int additionalProxyConstructorParametersCount, @NonNull @NonNull Object... parameters) Internal methods that handles the logic of instantiating a bean that has constructor interception applied.- Type Parameters:
T1
- The bean type- Parameters:
resolutionContext
- The resolution contextbeanContext
- The bean contextinterceptors
- The interceptors. Can be null and if so should be resolved from the context.definition
- The definitionconstructor
- The bean constructoradditionalProxyConstructorParametersCount
- The additional proxy constructor parameters countparameters
- The resolved parameters- Returns:
- The instantiated bean
- Since:
- 3.0.0
-
getParameterValues
Description copied from interface:InvocationContext
Returns the current state of the parameters as an array by parameter index. Note that mutations to the array have no effect. If you wish to mutate the parameters useInvocationContext.getParameters()
and theMutableArgumentValue
interface instead- Specified by:
getParameterValues
in interfaceInvocationContext<B,
R> - Returns:
- The bound
ArgumentValue
instances
-
getAttributes
Description copied from interface:MutableAttributeHolder
Overrides the defaultAttributeHolder.getAttributes()
method to return a mutable object.- Specified by:
getAttributes
in interfaceAttributeHolder
- Specified by:
getAttributes
in interfaceMutableAttributeHolder
- Returns:
- The mutable attributes
-
getParameters
Description copied from interface:InvocationContext
Returns the current parameters as a map of mutable argument values. This method allows mutation of the argument values and is generally more expensive than usingInvocationContext.getParameterValues()
andExecutable.getArguments()
directly, hence should be used with care.- Specified by:
getParameters
in interfaceInvocationContext<B,
R> - Returns:
- The bound
ArgumentValue
instances
-
proceed
Description copied from interface:InvocationContext
Proceeds with the invocation using the given interceptor as a position to start from. Mainly useful forIntroduction
advise where you want to invoke the target multiple times or where you want to repeat the entire chain.- Specified by:
proceed
in interfaceInvocationContext<B,
R> - Parameters:
from
- The interceptor to start from (note: will not be included in the execution)- Returns:
- The return value of the method
- Throws:
RuntimeException
- chain may throw RTE
-
resolveInterceptorValues
@NonNull protected static @NonNull Collection<AnnotationValue<?>> resolveInterceptorValues(@NonNull @NonNull AnnotationMetadata annotationMetadata, @NonNull @NonNull InterceptorKind kind) Resolve interceptor binding for the given annotation metadata and kind.- Parameters:
annotationMetadata
- The annotation metadatakind
- The kind- Returns:
- The binding
- Since:
- 3.3.0
