Simple Management of a Line Buffer, to be used by Interface
File Writers.
While a String is suitable to do that, this class ensures an
optimised Memory Management, because this is a hard point of
File Writing.

Public Member Functions | |
DEFINE_STANDARD_ALLOC | Interface_LineBuffer (const Standard_Integer size=10) |
Creates a LineBuffer with an absolute maximum size (Default value is only to satisfy compiler requirement) | |
void | SetMax (const Standard_Integer max) |
Changes Maximum allowed size of Buffer. If <max> is Zero, Maximum size is set to the initial size. | |
void | SetInitial (const Standard_Integer initial) |
Sets an Initial reservation for Blank characters (this reservation is counted in the size of the current Line) | |
void | SetKeep () |
Sets a Keep Status at current Length. It means that at next Move, the new line will begin by characters between Keep + 1 and current Length | |
Standard_Boolean | CanGet (const Standard_Integer more) |
Returns True if there is room enough to add <more> characters Else, it is required to Dump the Buffer before refilling it <more> is recorded to manage SetKeep status | |
Standard_CString | Content () const |
Returns the Content of the LineBuffer was C++ : return const | |
Standard_Integer | Length () const |
Returns the Length of the LineBuffer | |
void | Clear () |
Clears completely the LineBuffer | |
void | FreezeInitial () |
Inhibits effect of SetInitial until the next Move (i.e. Keep) Then Prepare will not insert initial blanks, but further ones will. This allows to cancel initial blanks on an internal Split A call to SetInitial has no effect on this until Move | |
void | Move (TCollection_AsciiString &str) |
Fills a AsciiString <str> with the Content of the Line Buffer, then Clears the LineBuffer | |
void | Move (const Handle< TCollection_HAsciiString > &str) |
Same as above, but <str> is known through a Handle | |
Handle_TCollection_HAsciiString | Moved () |
Same as above, but generates the HAsciiString | |
void | Add (const Standard_CString text) |
Adds a text as a CString. Its Length is evaluated from the text (by C function strlen) | |
void | Add (const Standard_CString text, const Standard_Integer lntext) |
Adds a text as a CString. Its length is given as <lntext> | |
void | Add (const TCollection_AsciiString &text) |
Adds a text as a AsciiString from TCollection | |
void | Add (const Standard_Character text) |
Adds a text made of only ONE Character |
