)

CoreExport void Insert	(	int	where,
		int	count = 0
	)

Remarks

Creates and inserts a new BitArray into sel.

Parameters:

int where

The index into sel indicating where to insert the new BitArray.

int count=0

The number of bits in the new BitArray.

CoreExport void Delete

(

int

where

)

Remarks

Deletes the specified BitArray from the sel list.

Parameters:

int where

The index into sel indicating which BitArray to delete.

CoreExport void SetSize	(	ShapeSSel &	selset,
		BOOL	save = FALSE
	)

CoreExport void SetSize	(	BezierShape &	shape,
		BOOL	save = FALSE
	)

Remarks

Sets the number of splines and allocates the corresponding number of BitArrays based on the shape passed. The size of each BitArray is set to the number of segments in each polyline.

Parameters:

BezierShape& shape

The shape whose splines determine the sizes set.

BOOL save=FALSE

TRUE to keep the previous BitArray contents. FALSE to discard it.

CoreExport void SetSize	(	PolyShape &	shape,
		BOOL	save = FALSE
	)

Remarks

Sets the number of splines and allocates the corresponding number of BitArrays based on the shape passed. The size of each BitArray is set to the number of segments in each spline.

Parameters:

PolyShape& shape

The shape whose lines determine the sizes set.

BOOL save=FALSE

TRUE to keep the previous BitArray contents. FALSE to discard it.

CoreExport IOResult Save

(

ISave *

isave

)

Remarks

Saves the ShapeSSel to disk.

CoreExport IOResult Load

(

ILoad *

iload

)

Remarks

Loads the ShapeSSel from disk.

Operators:

CoreExport bool Delete	(	const unsigned int *	pIndices,
		unsigned int	n
	)

Delete multiple entries at once.

Deleting multiple entries at once is faster than deleting one by one by calling Delete(), because the internal bookkeeping only needs to be done once.

\param[in] pIndices Pointer to an array of indices to delete.  Indices should be unique, and sorted in ascending order.
\param[in] n Number of entries in the indices array.
\return false if any of the vertex indices are invalid.
\see ShapeSSel::Delete
