Constructor Summary

Constructors

Constructor	Description
Personality()	base constructor, does nothing [except implicitly create _types_]
Personality(Personality<T> other)	initialise this personality with the bindings from _other_

Method Summary

Modifier and Type	Method	Description
<X extends T> Personality<T>	add(Class<X> interf, Implementation impl)	Add a new interface and its implementation to this Personality.
Personality<T>	add(Personality<T> p)	extend this personality by adding in all the mappings from the argument _p_.
Personality<T>	copy()	create a new Personality copying this one; the _types_ state is copied, not shared.
<X extends T> Implementation	getImplementation(Class<X> t)	get the implementation for the specified type, returning null if there isn't one available.
<X extends T> X	newInstance(Class<X> interf, Node n, EnhGraph that)	make a new instance of a type _interf_ based on the node _n_ and the polymorphic _that_; use the implementation wrapper for _interf_ in _types_.

Constructor Details

Personality

public Personality()

base constructor, does nothing [except implicitly create _types_]

Personality

public Personality(Personality<T> other)

initialise this personality with the bindings from _other_

Method Details

add

public <X extends T> Personality<T> add(Class<X> interf,
 Implementation impl)

Add a new interface and its implementation to this Personality.

Parameters:

interf - The interface to add, expressed as a Type object.

impl - A way of implementing _interf_.

copy

public Personality<T> copy()

create a new Personality copying this one; the _types_ state is copied, not shared.

getImplementation

public <X extends T> Implementation getImplementation(Class<X> t)

get the implementation for the specified type, returning null if there isn't one available.

add

public Personality<T> add(Personality<T> p)

extend this personality by adding in all the mappings from the argument _p_. return _this_ (for call chaining).

newInstance

public <X extends T> X newInstance(Class<X> interf,
 Node n,
 EnhGraph that)

make a new instance of a type _interf_ based on the node _n_ and the polymorphic _that_; use the implementation wrapper for _interf_ in _types_.
