C# Class Fan.Sys.Type

Type models a static type definition for an Obj class. A Type lifecycle: 1) Hollow: in this state we know basic identity of the type, and it's inheritance hierarchy. A type is setup to be hollow during Pod.load(). 2) Reflected: in this state we read all the slot definitions from the fcode to populate the slot tables used to for reflection. At this point clients can discover the signatures of the Type. 3) Emitted: the final state of loading a Type is to emit to a Java class called "fan.{pod}.{type}". Once emitted we can instantiate the type or call it's methods. 4) Finished: once we have reflected the slots into memory and emitted the Java class, the last stage is to bind the all the java.lang.reflect representations to the Slots for dynamic dispatch. We delay this until needed by Method or Field for a reflection invocation Type models sys::Type. Implementation classes are: - ClassType - GenericType (ListType, MapType, FuncType) - NullableType
Inheritance: FanObj, Literal

Method Description
@base ( ) : Type
@is ( Type type ) : bool
@params ( ) : Map
@typeof ( ) : Type
common ( object objs, int n ) : Type

Given a list of objects, compute the most specific type which they all share,or at worst return sys::Obj. This method does not take into account interfaces, only extends class inheritance.

doc ( ) : string
dotnetRepr ( ) : bool
emptyList ( ) : List
encode ( ObjEncoder @out ) : void
facet ( Type t ) : Facet
facet ( Type t, bool c ) : Facet
facets ( ) : List
field ( string name ) : Field
field ( string name, bool check ) : Field
fields ( ) : List
find ( string sig ) : Type
find ( string sig, bool check ) : Type
finish ( ) : void
fits ( Type type ) : bool
getRawType ( ) : Type

If this type is a generic parameter (V, L, etc), then return the actual type used in the Java method. For example V is Obj, and L is List. This is the type we actually use when constructing a signature for the invoke opcode.

hasFacet ( Type t ) : bool
inheritance ( ) : List
isAbstract ( ) : bool
isClass ( ) : bool
isConst ( ) : bool
isEnum ( ) : bool
isFacet ( ) : bool
isFinal ( ) : bool
isGeneric ( ) : bool
isGenericInstance ( ) : bool

A generic instance is a type which has "instantiated" a generic type and replaced all the generic parameter types with generic argument types. The type string[] is a generic instance of the generic type List (V is replaced with string). A generic instance always has a signature which different from the qname.

isGenericParameter ( ) : bool

Return if this type is a generic parameter (such as V or K) in a generic type (List, Map, or Method). Generic parameters serve as place holders for the parameterization of the generic type. Fantom has a predefined set of generic parameters which are always defined in the sys pod with a one character name.

isGenericType ( ) : bool

A generic type means that one or more of my slots contain signatures using a generic parameter (such as V or K). Fantom supports three built-in generic types: List, Map, and Method. A generic instance (such as string[]) is NOT a generic type (all of its generic parameters have been filled in). User defined generic types are not supported in Fan.
