# Interface_BitMap Class Reference

A bit map simply allows to associate a boolean flag to each
item of a list, such as a list of entities, etc... numbered
between 1 and a positive count nbitems
The BitMap class allows to associate several binary flags,
each of one is identified by a number from 0 to a count
which can remain at zero or be positive : nbflags
Flags lists over than numflag=0 are added after creation
Each of one can be named, hence the user can identify it
either by its flag number or by a name which gives a flag n0
(flag n0 0 has no name)
.

Standard_EXPORT Standard_Integer | AddFlag (const Standard_CString name="")
| Adds a flag, a name can be attached to it Returns its flag number Makes required reservation .
Standard_EXPORT Standard_Integer | AddSomeFlags (const Standard_Integer more)
| Adds several flags (<more>) with no name Returns the number of last added flag .
Standard_EXPORT Standard_Boolean | RemoveFlag (const Standard_Integer num)
| Removes a flag given its number. Returns True if done, false if num is out of range .
Standard_EXPORT Standard_Boolean | SetFlagName (const Standard_Integer num, const Standard_CString name)
| Sets a name for a flag, given its number name can be empty (to erase the name of a flag) Returns True if done, false if : num is out of range, or name non-empty already set to another flag .
Standard_EXPORT Standard_Integer | NbFlags () const
| Returns the count of flags (flag 0 not included) .
Standard_EXPORT Standard_Integer | Length () const
| Returns the count of items (i.e. the length of the bitmap) .
Standard_EXPORT Standard_CString | FlagName (const Standard_Integer num) const
| Returns the name recorded for a flag, or an empty string .
Standard_EXPORT Standard_Integer | FlagNumber (const Standard_CString name) const
| Returns the number or a flag given its name, or zero .
Standard_EXPORT Standard_Boolean | Value (const Standard_Integer item, const Standard_Integer flag=0) const
| Returns the value (true/false) of a flag, from : - the number of the item - the flag number, by default 0 .
Standard_EXPORT void | SetValue (const Standard_Integer item, const Standard_Boolean val, const Standard_Integer flag=0) const
| Sets a new value for a flag .
Standard_EXPORT void | SetTrue (const Standard_Integer item, const Standard_Integer flag=0) const
| Sets a flag to True .
Standard_EXPORT void | SetFalse (const Standard_Integer item, const Standard_Integer flag=0) const
| Sets a flag to False .
Standard_EXPORT Standard_Boolean | CTrue (const Standard_Integer item, const Standard_Integer flag=0) const
| Returns the former value for a flag and sets it to True (before : value returned; after : True) .
Standard_EXPORT Standard_Boolean | CFalse (const Standard_Integer item, const Standard_Integer flag=0) const
| Returns the former value for a flag and sets it to False (before : value returned; after : False) .
Standard_EXPORT void | Init (const Standard_Boolean val, const Standard_Integer flag=0) const
| Initialises all the values of Flag Number <flag> to a given value <val> .
