Public Methods

virtual XxxBool	CanCastFrom (XxxBasicType SourceType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo) Determines if this ADT can cast an object of another type into its own type
virtual XxxBool	CanCastTo (XxxBasicType TargetType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo) Determines if this ADT can cast an object of its type into another type
virtual XxxErrCode	CastFrom (XxxBasicType SourceType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo, XxxADTValue* OldObject, XxxADTValue* NewObject) Executes a cast from another type into this type
virtual XxxErrCode	CastTo (XxxBasicType TargetType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo, XxxADTValue* OldObject, XxxADTValue* NewObject) Executes a cast from this type into another type
virtual XxxErrCode	CopyHToN (const XxxADTValue* SrcObject, XxxADTValue *ResultObject, const XxxADTMetaInfo* MetaInfo) Never gets called for core types
virtual XxxErrCode	CopyNToH (const XxxADTValue* SrcObject, XxxADTValue *ResultObject, const XxxADTMetaInfo* MetaInfo) Never gets called for core types
virtual XxxErrCode	DefaultVal (XxxADTValue* Object, const XxxADTMetaInfo* MetaInfo) Assigns a "default" value, if any exists
static inline XxxBool	IsCoreADT (XxxBasicType TypeId) / Is TypeId a CoreADT?
static inline XxxBool	SEquals (XxxBasicType TypeId, const XxxADTValue* Obj1, const XxxADTMetaInfo* MI1, const XxxADTValue* Obj2, const XxxADTMetaInfo* MI2) / Are the two values equal?
static inline int	ValueOffset (XxxBasicType TypeId) This is used to find the offset of the actual value of a core value

class BasicStats: public XxxADTClass::TypeStats

Statistics root class for CORE ADTs

static inline XxxBool IsCoreADT(XxxBasicType TypeId)

/ Is TypeId a CoreADT?

static inline int ValueOffset(XxxBasicType TypeId)

This is used to find the offset of the actual value of a core value. It is insufficient to use sizeof, since the compiler might align doubles to 8-byte boundaries.

static inline XxxBool SEquals(XxxBasicType TypeId, const XxxADTValue* Obj1, const XxxADTMetaInfo* MI1, const XxxADTValue* Obj2, const XxxADTMetaInfo* MI2)

/ Are the two values equal?

virtual XxxErrCode DefaultVal(XxxADTValue* Object, const XxxADTMetaInfo* MetaInfo)

Assigns a "default" value, if any exists

virtual XxxBool CanCastFrom(XxxBasicType SourceType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo)

Determines if this ADT can cast an object of another type into its own type

Parameters:

SourceType - The type to cast from
SourceMetaInfo - The meta info of the object to be casted
TargetMetaInfo - The meta info of the new object to be created

virtual XxxErrCode CastFrom(XxxBasicType SourceType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo, XxxADTValue* OldObject, XxxADTValue* NewObject)

Executes a cast from another type into this type

Parameters:

CastType - The type id of the old object
SourceMetaInfo - The meta info of the object to be casted
TargetMetaInfo - The meta info of the new object to be created
OldObject - The object to be casted
NewObject - The new object to be created

virtual XxxBool CanCastTo(XxxBasicType TargetType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo)

Determines if this ADT can cast an object of its type into another type

Parameters:

TargetType - The type to cast to
SourceMetaInfo - The meta info of the object to be casted
TargetMetaInfo - The meta info of the new object to be created

virtual XxxErrCode CastTo(XxxBasicType TargetType, const XxxADTMetaInfo* SourceMetaInfo, const XxxADTMetaInfo* TargetMetaInfo, XxxADTValue* OldObject, XxxADTValue* NewObject)

Parameters:

CastType - The type id of the new object
SourceMetaInfo - The meta info of the object to be casted
TargetMetaInfo - The meta info of the new object to be created
OldObject - The object to be casted
NewObject - The new object to be created

virtual XxxErrCode CopyHToN(const XxxADTValue* SrcObject, XxxADTValue *ResultObject, const XxxADTMetaInfo* MetaInfo)

Never gets called for core types

virtual XxxErrCode CopyNToH(const XxxADTValue* SrcObject, XxxADTValue *ResultObject, const XxxADTMetaInfo* MetaInfo)

Never gets called for core types
