Parent Classes:

public RCHandleC<class Bod>

VLExprLabelC()

Default constructor.
Creates an invalid handle.

VLExprLabelC(const VLExprLabelC & oth)

Copy constructor.

VLExprLabelC(VLExprLabel & oth)

Body Constructor.

VLExprLabelC(StringC name,BooleanT unique = FALSE)

Construct a named label.
If unique is false, the label will be entered in a global table and reused every time a symbol of that name is requested.

Otherwise the label will just be created with the given name.

VLExprLabelC(StringC name,VLExprTypeC & typed)

Construct a named, typed label

BooleanT IsArgTyped() const

Does argument have a preset type ?

BooleanT IsSymbsOnly() const

Will arg contain only simple symbols only ?
Use in indexing.

void SetSymbsOnly(BooleanT val = TRUE)

Set symbol only flag.

VLExprTypeC GetArgType() const

Get type of arg.

void SetValType(VLExprTypeC & nType)

Set type of arg.

int GetIndexPri(void) const

Get indexing priority.

void SetIndexPri(int Val)

Set indexing priority.
Use to give hints to the expression matcher.

StringC GetName(StringC Buff = StringC()) const

Get label name and type.

StringC Name() const

Get label name and type.

StringC GetLabelName() const

Get label name.

UIntT Hash() const

Get a hash value.

HashARC<StringC,VLExprLabelC> & StringMap()

Map Strings to ExprLabel's
FIXME :- If we want the logic library to be multi-threaded then this needs a semaphore. protected:

VLExprLabel & Body()

Get refrence to label.

const VLExprLabel & Body() const

Get refrence to label.

BooleanT IsValid() const

Check its a valid handle.

BooleanT IsValidObject() const

Check its a valid handle, and that the object is pointed to is also valid.

RCHandleC<VLExprLabel> & operator=(const RCHandleC<VLExprLabel> & oth)

Assignment.

BooleanT operator==(const RCHandleC<VLExprLabel> & oth) const

Comparison operator.

BooleanT operator!=(const RCHandleC<VLExprLabel> & oth) const

Comparison operator.

UIntT Hash() const

Hash function.x

BooleanT IsConst() const

Is object constant ?

BooleanT IsNotConst() const

Is object not constant ?

void SetConst(void) const

Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:

void Invalidate()

Turn this into an invalid handle.

VLExprLabel & Body()

Direct access to body.

const VLExprLabel & Body() const

Constant access to body.
