What is difference between @Inject and @InjectComponent since we declare it before component.

[Chung Khanh Duy <ch...@gmail.com>]

Hi experts,

I have a snippet code as below:

@Inject
private Zone tZone;

@InjectComponent
private Zone tZone;

So I don't understand what is difference  if I use @Inject or
@InjectComponent for component in Tapestry ? If anyone knows, can you
please let me know why. I really appreciate.

Thanks,
Duy.

This is declaring a component instance. This supposes you just use <div  
t:id="tZone"> in the template. I used div as an example, but any tag is  
valid.

This is just injecting a component declared in the template.

The following applies to components only, not services.

@Inject is backed by InjectWorker which ultimately delegates to
InjectionProvider2. InjectionProvider2 is a chain which can be contributed
to. See TapestryModule.provideStandardInjectionProviders() for the
defaults. Some of the notable options for @Inject are assets, blocks and
services but you can provide your own.

@InjectComponent can only inject components by id (see
InjectComponentWorker).
