Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.

class LineFontDefPattern from IGESGraph inherits LineFontEntity

|
|
---Purpose : defines IGESLineFontDefPattern, Type <304> Form <2>
|
|
-- in package IGESGraph
|
|
--
|
|
-- Line Font may be defined by repetition of a basic pattern
|
|
-- of visible-blank(or, on-off) segments superimposed on
|
|
-- a line or a curve. The line or curve is then displayed
|
|
-- according to the basic pattern.

|
|
---Purpose : This method is used to set the fields of the class

|
-- LineFontDefPattern
|
|
-- - allSegLength : Containing lengths of respective segments
|
|
-- - aPattern : HAsciiString indicating visible-blank segments

NbSegments (me) returns Integer;
|
|
---Purpose : returns the number of segments in the visible-blank pattern
|
|
|
|
Length (me; Index : Integer) returns Real
|
|
raises OutOfRange;
|
|
---Purpose : returns the Length of Index'th segment of the basic pattern
|
|
-- raises exception if Index <= 0 or Index > NbSegments
|
|
|
|
DisplayPattern (me) returns HAsciiString from TCollection;
|
|
---Purpose : returns the string indicating which segments of the basic
|
|
-- pattern are visible and which are blanked.
|
|
-- e.g:
|
|
-- theNbSegments = 5 and if Bit Pattern = 10110, which means that
|
|
-- segments 2, 3 and 5 are visible, whereas segments 1 and 4 are
|
|
-- blank. The method returns "2H16" as the HAsciiString.
|
|
-- Note: The bits are right justified. (16h = 10110)
|
|
|
|
IsVisible (me; Index : Integer) returns Boolean;
|
|
---Purpose : The Display Pattern is decrypted to
|
|
-- return True if the Index'th basic pattern is Visible,
|
|
-- False otherwise.
|
|
-- If Index > NbSegments or Index <= 0 then return value is
|
|
-- False.
