Method Detail

inject

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

Initializes the component by performing injection.

Parameters:

component - component instance to inject

targets - the injection resolvers to resolve all injection points

Throws:

ComponentException - if injection failed for some reason.

inject

public void inject(Object component,
                   Inhabitant<?> onBehalfOf,
                   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,
                   Inhabitant<?> onBehalfOf,
                   ExecutorService es,

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:

                   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,
