Method Detail

inject

public void inject(Object component,
          InjectionResolver... targets)

Initializes the component by performing injection.

Parameters:

component - component instance to inject

onBehalfOf - the inhabitant to do injection on behalf of

targets - the injection resolvers to resolve all injection points

Throws:

ComponentException - if injection failed for some reason.

inject

public void inject(Object component,
          ExecutorService es,
          InjectionResolver... targets)

Initializes the component by performing injection.

Parameters:

component - component instance to inject

onBehalfOf - the inhabitant to do injection on behalf of

es - the ExecutorService to use in order to handle the work load

targets - the injection resolvers to resolve all injection points

Throws:

ComponentException - if injection failed for some reason.

inject

public void inject(Object component,
          Class type,
          InjectionResolver... targets)

Initializes the component by performing injection.

Parameters:

component - component instance to inject

type - component class

targets - the injection resolvers to resolve all injection points

Throws:

ComponentException - if injection failed for some reason.

syncDoInject

protected void syncDoInject(Object component,
                Class type,
                InjectionResolver... targets)

Initializes the component by performing injection.

Parameters:

component - component instance to inject

onBehalfOf - the inhabitant to do injection on behalf of

type - component class

targets - the injection resolvers to resolve all injection points

Throws:

ComponentException - if injection failed for some reason.

error_injectionException

protected void error_injectionException(InjectionResolver target,
                            Annotation inject,
                            AnnotatedElement injectionPoint,
                            Throwable e)

allowInjection
