getKind
@NonNull public InterceptorKind getKind()
- Specified by:
getKind
in interfaceInvocationContext<T,T>
- Returns:
- An enum representing the kind of interception that is occurring.
-
getTarget
public T getTarget()
- Specified by:
getTarget
in interfaceInvocationContext<T,T>
- Returns:
- The target object
-
proceed
public T proceed() throws java.lang.RuntimeException
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:
java.lang.RuntimeException
- chain may throw RTE
-
getArguments
@NonNull public io.micronaut.core.type.Argument<?>[] getArguments()
-
getConstructor
@NonNull public io.micronaut.core.beans.BeanConstructor<T> getConstructor()
- Specified by:
getConstructor
in interfaceConstructorInvocationContext<T>
- Returns:
- The bean type.
-
instantiate
@Internal @NonNull @Deprecated public static <T1> T1 instantiate(@NonNull io.micronaut.context.BeanResolutionContext resolutionContext, @NonNull io.micronaut.context.BeanContext beanContext, @Nullable java.util.List<io.micronaut.context.BeanRegistration<Interceptor<T1,T1>>> interceptors, @NonNull io.micronaut.inject.BeanDefinition<T1> definition, @NonNull io.micronaut.core.beans.BeanConstructor<T1> constructor, @NonNull java.lang.Object... parameters)
Deprecated.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 constructorparameters
- Th resolved parameters- Returns:
- The instantiated bean
- Since:
- 3.0.0

instantiate
@Internal @NonNull public static <T1> T1 instantiate(@NonNull io.micronaut.context.BeanResolutionContext resolutionContext, @NonNull io.micronaut.context.BeanContext beanContext, @Nullable java.util.List<io.micronaut.context.BeanRegistration<Interceptor<T1,T1>>> interceptors, @NonNull io.micronaut.inject.BeanDefinition<T1> definition, @NonNull io.micronaut.core.beans.BeanConstructor<T1> constructor, int additionalProxyConstructorParametersCount, @NonNull java.lang.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
@NonNull public java.lang.Object[] 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
@NonNull public io.micronaut.core.convert.value.MutableConvertibleValues<java.lang.Object> getAttributes()
- Specified by:
getAttributes
in interfaceio.micronaut.core.attr.AttributeHolder
- Specified by:
getAttributes
in interfaceio.micronaut.core.attr.MutableAttributeHolder
-
getParameters
@NonNull public java.util.Map<java.lang.String,io.micronaut.core.type.MutableArgumentValue<?>> 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
public R proceed(@NonNull Interceptor from) throws java.lang.RuntimeException
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:
java.lang.RuntimeException
- chain may throw RTE
-
resolveInterceptorValues
@NonNull protected static java.util.Collection<io.micronaut.core.annotation.AnnotationValue<?>> resolveInterceptorValues(@NonNull io.micronaut.core.annotation.AnnotationMetadata annotationMetadata, @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
