Data Members:
int polys;

The number of splines in the shape.

BitArray sel;

One bit for each spline in the shape.

BOOL  save = FALSE 
)
Remarks

The shape whose splines determine the sizes set.

BOOL save=FALSE

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

◆ SetSize() [3/3]

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

The shape whose lines determine the sizes set.

BOOL save=FALSE

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

◆ Set() [1/2]

CoreExport void Set ( int  index)
Remarks
Sets the bit specified by the index to 1.
Parameters:
int index

The bit to set.

◆ Set() [2/2]

CoreExport void Set ( int  index,
int  value 
)
Remarks
Sets the bit specified by the index to the value passed.
Parameters:
int index

The bit to set or clear.

int value

The value to set, either 0 or 1.

◆ Clear()

CoreExport void Clear ( int  index)
Remarks
Clears the bit specified by the index to 1.
Parameters:

CoreExport BOOL IsCompatible ( const PolyShape shape) const

◆ Save()

CoreExport IOResult Save ( ISave isave)
Remarks
Saves the BitArray to disk.

◆ Load()

CoreExport IOResult Load ( ILoad iload)
Remarks
Loads the BitArray from disk.
Operators:

◆ Delete() [2/2]

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.

Parameters
[in]pIndicesPointer to an array of indices to delete. Indices should be unique, and sorted in ascending order.
[in]nNumber of entries in the indices array.
Returns
false if any of the vertex indices are invalid.
