Example 1 with DefaultBeanContext

use of io.micronaut.context.DefaultBeanContext in project micronaut-core by micronaut-projects.

the class ConstructorInterceptorChain method instantiate.

/**
 * Internal methods that handles the logic of instantiating a bean that has constructor interception applied.
 *
 * @param resolutionContext                         The resolution context
 * @param beanContext                               The bean context
 * @param interceptors                              The interceptors. Can be null and if so should be resolved from the context.
 * @param definition                                The definition
 * @param constructor                               The bean constructor
 * @param additionalProxyConstructorParametersCount The additional proxy constructor parameters count
 * @param parameters                                The resolved parameters
 * @param <T1>                                      The bean type
 * @return The instantiated bean
