Class BlockInjectionProvider

java.lang.Object
  org.apache.tapestry5.internal.services.BlockInjectionProvider

All Implemented Interfaces:

InjectionProvider2

public class BlockInjectionProvider
extends Object
implements InjectionProvider2

Identifies fields of type Block that have the Inject annotation and converts them into read-only fields containing the injected Block from the template. The annotation's value is the id of the block to inject; if omitted, the block id is deduced from the field id.

Must be scheduled before DefaultInjectionProvider because it uses the same annotation, Inject, with a different interpretation.
