Inheritance diagram for Vireo::EquivalenceType:

Public Member Functions
virtual void	Visit (TypeVisitor *tv)
virtual void *	Begin (PointerAccessEnum mode)
virtual NIError	InitData (void *pData, TypeRef pattern=null)
	Initialize (re)initialize a value to the default value for the Type. Buffer must be well formed.
virtual NIError	CopyData (const void *pData, void *pDataCopy)
	May a deep copy fom the source to the copy.
virtual NIError	ClearData (void *pData)
	Free up any storage and put value to null/zero state.
Public Member Functions inherited from Vireo::AggregateType
virtual Int32	SubElementCount ()
	How many element in an Aggregate, 0 if the type is not an Aggregate.
virtual TypeRef	GetSubElementByName (SubString *name)
	Get an element of an Aggregate using the elements field name.
virtual TypeRef	GetSubElement (Int32 index)
	Get an element of an Aggregate using it index.
Public Member Functions inherited from Vireo::TypeCommon
	TypeCommon (TypeManagerRef typeManager)
TypeManagerRef	TheTypeManager ()
TypeRef	Next ()
EncodingEnum	BitEncoding ()
	How the data as a whole is encoded, either a simple encoding like "2s compliment binary" or an Aggregate encoding.
Int32	AQAlignment ()
	Memory alignment required for values of this type.
Int32	TopAQSize ()
	Amount of memory needed for the top level data structure for the type including any padding if needed.
Boolean	HasCustomDefault ()
	True if the initial value for data of this type is not just zeroed out memory.
Boolean	IsMutableValue ()
	True if the initial value can be changed.
Int32	Rank ()
	Dimensionality of the type. Simple Scalars are Rank 0, arrays can be rank 0 as well.
Boolean	IsArray ()
	True if the type is an indexable container that contains another type.
Boolean	IsFlat ()
	True if data can be copied by a simple block copy.
Boolean	IsValid ()
	True if all types the type is composed of have been resolved to valid types.
Boolean	IsBitLevel ()
	True if the type a BitBlock or a BitClusters.
Boolean	HasPadding ()
	True if TopAQSize includes internal or external padding necessary for proper aligmnet of multiple elements.
Boolean	HasGenericType ()
	True if the type contains one or more generic types.
Boolean	IsInputParam ()
	True if aggregate element is used as an input parameter.
Boolean	IsOutputParam ()
	True if aggregate element is used as an output parameter.
Boolean	IsAlias ()
	True if aggregate element is owned elsewhere (e.g. its an i ,o ,io, or alias) .
Boolean	IsStaticParam ()
	True if the parameer is only visible to the callee, and is preserved between calls.
Boolean	IsTempParam ()
	True is the parameter is only visible to the callee, but may be cleared between calls.
Boolean	IsOptionalParam ()
	True if the parameter is not required. For non flat values null may be passed in.
UsageTypeEnum	ElementUsageType ()
PointerTypeEnum	PointerType ()
	What type of internal pointer is this type. Only used for CustomValuePointers.
virtual TypeRef	BaseType ()
	For a wrapped type, return the type that was wrapped, null otherwise.
TypeRef	GetSubElementOffsetFromPath (SubString *name, Int32 *offset)
	Parse through a path, digging through Aggregate element names. Calculates the cumulative offset. More...
TypeRef	GetSubElementInstancePointerFromPath (SubString *name, void *start, void **end, Boolean allowDynamic)
	Parse through a path, digging through Aggregate element names, references and array indexes. More...
virtual void	GetName (SubString *name)
	Set the SubString to the name if the type is not anonymous.
virtual void	GetElementName (SubString *name)
	Set the SubString to the aggregates elements field name.
virtual IntIndex *	GetDimensionLengths ()
	Return a pointer to the raw vector of dimension lengths.
virtual IntIndex	ElementOffset ()
	Offset in AQs in the containing aggregate.
void	ZeroOutTop (void *pData)
	Zero out a buffer that will hold a value of the type without consideration for the existing bits.
NIError	InitData (void *pData, IntIndex count)
	Initialize a linear block to the deault value for the type.
NIError	CopyData (const void *pData, void *pDataCopy, IntIndex count)
	Deep copy a linear block of values from one locatio to another.
NIError	ClearData (void *pData, IntIndex count)
	Dealocate and null out a linear block of value of the type.
NIError	MultiCopyData (const void *pSingleData, void *pDataCopy, IntIndex count)
	Make multiple copies of a single instance to a linear block.
Boolean	CompareType (TypeRef otherType)
Boolean	IsA (const SubString *name)
Boolean	IsA (TypeRef otherType, Boolean compatibleArrays)
virtual Int32	BitSize ()
	Size of the type in bits including padding. If the type is bit level it s the raw bit size wiht no padding.
