Class CachingConstructorInjectionComponentAdapter

java.lang.Object

org.picocontainer.defaults.AbstractComponentAdapter

com.intellij.util.pico.CachingConstructorInjectionComponentAdapter

All Implemented Interfaces:

ComponentAdapter

public final class CachingConstructorInjectionComponentAdapter
extends AbstractComponentAdapter

A drop-in replacement of ConstructorInjectionComponentAdapter The same code (generified and cleaned up) but without constructor caching (hence taking up less memory). This class also inlines instance caching (e.g. it doesn't need to be wrapped in a CachingComponentAdapter).

Method Detail

getComponentInstance

public java.lang.Object getComponentInstance(PicoContainer container)
                                      throws PicoInitializationException,
                                             PicoIntrospectionException,
                                             AssignabilityRegistrationException

Parameters:

container - the PicoContainer, that is used to resolve any possible dependencies of the instance.

Returns:

the component instance.

Throws:

PicoInitializationException - if the component could not be instantiated.

PicoIntrospectionException - if the component has dependencies which could not be resolved, or instantiation of the component lead to an ambigous situation within the container.

AssignabilityRegistrationException

createDefaultParameters

protected Parameter[] createDefaultParameters(java.lang.Class<?>[] parameters)
