                           boolean custom)

Constructor

Parameters:

type - The type that will be instantiated

custom - if true indicates this is a custom TypeInstantiator implementation, as opposed to one generated by the dependency injection runtime

Method Detail

isCustom

public boolean isCustom()

Indicates if this is a custom instantiator for this type, or a generic one provided by the dependency injection framework

Returns:

true if this is a custom instantiator, false if this is a generic instantiator

load

public abstract T load(InstanceLocator locator)
                throws TypeDependencyNotAvailableException

Instantiate the instance of T

Parameters:

locator - The InstanceLocator that provides the dependencies required to instantiate T

Returns:

instance of T

Throws:

TypeDependencyNotAvailableException - if the type could not be instantiated

type

public final Class<T> type()

The type that will be instantiated

Returns:

The type that this TypeInstantiator instantiates

notAvailable

protected final TypeDependencyNotAvailableException notAvailable(Throwable cause)
