requiredParentKeys

public java.util.Set<Key<?>> requiredParentKeys()

Overrides:

requiredParentKeys in class Node<T>

createArguments

protected java.lang.Object[] createArguments()

Create an array of arguments for instantiation method invocation.

Returns:

an array of objects to serve as method arguments

injectFields

protected T injectFields(T instance)
                  throws java.lang.IllegalAccessException

Perform in-place field injection into an object instance.

Parameters:

instance - to inject fields into

Returns:

an original object instance with injected fields

Throws:

java.lang.IllegalAccessException - if we cannot access the field to inject the value into

equals

Checks if current Class is either Provider or Supplier.

Parameters:

clazz - to check

Returns:

true, if the Class is either Provider or Supplier
