org.picocontainer.injectors
Class SingleMemberInjector<T>

java.lang.Object
  org.picocontainer.adapters.AbstractAdapter<T>
      org.picocontainer.injectors.AbstractInjector<T>
          org.picocontainer.injectors.SingleMemberInjector<T>

All Implemented Interfaces:

Serializable, ComponentAdapter<T>, ComponentMonitorStrategy, Injector<T>

Direct Known Subclasses:

ConstructorInjector, MethodInjector

public abstract class SingleMemberInjector<T>
extends AbstractInjector<T>

Injection will happen in a single member function on the component.

Constructor Detail

SingleMemberInjector

public SingleMemberInjector(Object componentKey,
                            Class componentImplementation,
                            Parameter[] parameters,
                            ComponentMonitor monitor,
                            boolean useNames)

Method Detail

getParanamer

protected Paranamer getParanamer()

getMemberArguments

protected Object[] getMemberArguments(PicoContainer container,
                                      AccessibleObject member,
                                      Type[] parameterTypes,
                                      Annotation[] bindings)

boxParameters

protected void boxParameters(Type[] parameterTypes)

getParameter

protected Object getParameter(PicoContainer container,
                              AccessibleObject member,
                              int i,
                              Type parameterType,
                              Annotation binding,
                              Parameter currentParameter,
                              ComponentAdapter<?> injecteeAdapter)

nullCheck

protected void nullCheck(AccessibleObject member,
                         int i,
                         ParameterNameBinding expectedNameBinding,
                         Object result)

isNullParamAllowed

protected boolean isNullParamAllowed(AccessibleObject member,
                                     int i)

Checks to see if a null parameter is allowed in the given constructor/field/method. The default version allows null if the target object is not a primitive type.

Parameters:

member - constructor method or field

i - parameter #.

Returns:

true if the null parameter might be allowed.

getBindings

protected Annotation[] getBindings(Annotation[][] annotationss)
