Class BlockInjectionProvider

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

All Implemented Interfaces:

InjectionProvider

public class BlockInjectionProvider
extends Object
implements InjectionProvider

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.

public boolean provideInjection(String fieldName,
                                Class fieldType,
                                ObjectLocator locator,

Description copied from interface: InjectionProvider

Peform the injection, if possible. Most often, this will result in a call to ClassTransformation.injectField(String, Object). The caller is responsible for invoking ClassTransformation.claimField(String, Object).

Specified by:

provideInjection in interface InjectionProvider

Parameters:

fieldName - the name of the field requesting injection

fieldType - the type of the field

locator - allows services to be located

transformation - allows the code for the class to be transformed

componentModel - defines the relevant aspects of the component

Returns:

true if an injection has been made (terminates the command chain), false to continue down the chain
