Detailed Description

Class BitArray, Class PolyShape.

Description:
This class stores and provides access to shape vertex selection data. All methods of this class are implemented by the system.
Data Members:
int polys;

The number of splines in the shape.

BitArray *sel;

An array of BitArrays, one for each spline.

Constructor & Destructor Documentation

◆ ShapeVSel() [1/2]

Remarks
Constructor. The number of splines is set to 0. The BitArray pointer is set to NULL.

◆ ShapeVSel() [2/2]

CoreExport ShapeVSel ( const ShapeVSel from)

◆ ~ShapeVSel()

Member Function Documentation

◆ operator=()

CoreExport ShapeVSel & operator= ( const ShapeVSel from)
Remarks
Assignment operator.

◆ operator==()

CoreExport BOOL operator== ( const ShapeVSel s) const

◆ Insert()

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.

◆ Delete() [1/2]

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.

◆ SetSize() [1/3]

CoreExport void SetSize ( ShapeVSel selset,
BOOL  save = FALSE 
)

◆ SetSize() [2/3]

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 vertices 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.

◆ SetSize() [3/3]

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 vertices 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.

◆ operator[]()

CoreExport BitArray & operator[] ( int  index)

◆ ClearAll()

CoreExport void ClearAll ( )
Remarks
Clears every bit for every poly.

◆ SetAll()

CoreExport void SetAll ( )

◆ Toggle()

CoreExport void Toggle ( )

◆ Empty()

Remarks
Sets the size of every poly BitArray to 0.

◆ IsCompatible() [1/3]

CoreExport BOOL IsCompatible ( const ShapeVSel selset) const

◆ IsCompatible() [2/3]

CoreExport BOOL IsCompatible ( const BezierShape shape) const

◆ IsCompatible() [3/3]

CoreExport BOOL IsCompatible ( const PolyShape shape) const

◆ Save()

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

◆ Load()

CoreExport IOResult Load ( ILoad iload)
Remarks
Loads the ShapeVSel 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.
