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)

Public Member Functions | |
DEFINE_STANDARD_ALLOC | Interface_BitMap () |
Creates a empty BitMap | |
Interface_BitMap (const Standard_Integer nbitems, const Standard_Integer resflags=0) | |
Creates a BitMap for <nbitems> items One flag is defined, n0 0 <resflags> prepares allocation for <resflags> more flags Flags values start at false | |
void | Initialize (const Standard_Integer nbitems, const Standard_Integer resflags=0) |
Initialize empty bit by <nbitems> items One flag is defined, n0 0 <resflags> prepares allocation for <resflags> more flags Flags values start at false | |
Interface_BitMap (const Interface_BitMap &other, const Standard_Boolean copied=Standard_False) | |
Creates a BitMap from another one if <copied> is True, copies data else, data are not copied, only the header object is | |
void | Initialize (const Interface_BitMap &other, const Standard_Boolean copied=Standard_False) |
Initialize a BitMap from another one | |
void | Internals (Standard_Integer &nbitems, Standard_Integer &nbwords, Standard_Integer &nbflags, Handle< TColStd_HArray1OfInteger > &flags, Handle< TColStd_HSequenceOfAsciiString > &names) const |
Returns internal values, used for copying Flags values start at false | |
void | Reservate (const Standard_Integer moreflags) |
Reservates for a count of more flags | |
void | SetLength (const Standard_Integer nbitems) |
Sets for a new count of items, which can be either less or greater than the former one For new items, their flags start at false | |
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_Integer | AddSomeFlags (const Standard_Integer more) |
Adds several flags (<more>) with no name Returns the number of last added flag | |
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_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_Integer | NbFlags () const |
Returns the count of flags (flag 0 not included) | |
Standard_Integer | Length () const |
Returns the count of items (i.e. the length of the bitmap) | |
Standard_CString | FlagName (const Standard_Integer num) const |
Returns the name recorded for a flag, or an empty string | |
Standard_Integer | FlagNumber (const Standard_CString name) const |
Returns the number or a flag given its name, or zero | |
Standard_Boolean | Value (const Standard_Integer item, const Standard_Integer flag=0) const |
Returns the value (true/false) of a flag, from : | |
void | SetValue (const Standard_Integer item, const Standard_Boolean val, const Standard_Integer flag=0) const |
Sets a new value for a flag | |
void | SetTrue (const Standard_Integer item, const Standard_Integer flag=0) const |
Sets a flag to True | |
void | SetFalse (const Standard_Integer item, const Standard_Integer flag=0) const |
Sets a flag to False | |
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_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) | |
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> | |
void | Clear () |
Clear all field of bit map |
