Method Detail

doInitialize

void doInitialize()

Description copied from class: RealOptionalBinder.RealOptionalBinderProviderWithDependencies

Initialize the factory. BindingSelection is guaranteed to be initialized at this point and this will be called prior to any provisioning.

Specified by:

doInitialize in class RealOptionalBinder.RealOptionalBinderProviderWithDependencies<T,T>

doProvision

protected T doProvision(InternalContext context,
                        Dependency<?> dependency)
                 throws InternalProvisionException

Description copied from class: InternalProviderInstanceBindingImpl.Factory

Specified by:

doProvision in class InternalProviderInstanceBindingImpl.Factory<T>

Returns:

instance to be injected

Throws:

InternalProvisionException - if a value cannot be provided

getDependencies
