Examples of org.apache.tapestry.ioc.ObjectProvider.provide()

org.apache.tapestry.ioc.ObjectProvider.provide()

Provides an object based on an expression. The process of providing objects occurs within a particular context, which will typically be a service builder method, service contributor method, or service decorator method. The locator parameter provides access to the services visible to that context. @param objectType the expected object type @param annotationProvider provides access to annotations (typically, the field or parameter to which an injection-related annotation is attached); annotations on the field or parameter may also be used when resolving the desired object @param locator locator for the context in which the provider is being used @param < T> @return the requested object, or null if this object provider can not supply an object @throws RuntimeException if the expression can not be evaluated, or the type of object identified is not assignable to the type specified by the objectType parameter
