Detailed Description

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.

Constructor & Destructor Documentation

◆ Interface_LineBuffer()

Interface_LineBuffer::Interface_LineBuffer ( const Standard_Integer size = 10 )

Creates a LineBuffer with an absolute maximum size (Default value is only to satisfy compiler requirement)

Member Function Documentation

◆ Add() [1/4]

void Interface_LineBuffer::Add ( const Standard_CString text )

Adds a text as a CString. Its Length is evaluated from the text (by C function strlen)

◆ Add() [2/4]

void Interface_LineBuffer::Add	(	const Standard_CString	text,
		const Standard_Integer	lntext
	)

Adds a text as a CString. Its length is given as <lntext>

◆ Add() [3/4]

void Interface_LineBuffer::Add ( const TCollection_AsciiString & text )

Adds a text as a AsciiString from TCollection.

◆ Add() [4/4]

void Interface_LineBuffer::Add ( const Standard_Character text )

Adds a text made of only ONE Character.

◆ CanGet()

Standard_Boolean Interface_LineBuffer::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.

◆ Clear()

void Interface_LineBuffer::Clear ( )

Clears completely the LineBuffer.

◆ Content()

Standard_CString Interface_LineBuffer::Content ( ) const

inline

Returns the Content of the LineBuffer.

◆ FreezeInitial()

void Interface_LineBuffer::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.

◆ Length()

Standard_Integer Interface_LineBuffer::Length ( ) const

inline

Returns the Length of the LineBuffer.

◆ Move() [1/2]

void Interface_LineBuffer::Move ( TCollection_AsciiString & str )

Fills a AsciiString <str> with the Content of the Line Buffer, then Clears the LineBuffer.

◆ Move() [2/2]

void Interface_LineBuffer::Move ( const Handle< TCollection_HAsciiString > & str )

Same as above, but <str> is known through a Handle.

◆ Moved()

Handle< TCollection_HAsciiString > Interface_LineBuffer::Moved ( )

Same as above, but generates the HAsciiString.

◆ SetInitial()

void Interface_LineBuffer::SetInitial ( const Standard_Integer initial )

Sets an Initial reservation for Blank characters (this reservation is counted in the size of the current Line)

◆ SetKeep()

void Interface_LineBuffer::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.

◆ SetMax()

void Interface_LineBuffer::SetMax ( const Standard_Integer max )

Changes Maximum allowed size of Buffer. If <max> is Zero, Maximum size is set to the initial size.
