TopTools

The TopTools package provides utilities for the topological data structure.

ShapeMapHasher. Hash a Shape base on the TShape and the Location. The Orientation is not used.
OrientedShapeMapHasher. Hash a Shape base on the TShape ,the Location and the Orientation.

TopTools_LocationSet

The class LocationSet stores a set of location in a relocatable state.
It can be created from Locations.
It can create Locations.
It can be write and read from a stream.

Constructors(1)

constructor(): TopTools_LocationSet
Returns an empty set of locations.

Instance methods(4)

Clear(): void
Clears the content of the set.
Add(L: TopLoc_Location): number
Incorporate a new Location in the set and returns its index.
Parameters (1)
- L
Location(I: number): TopLoc_Location
Returns the location of index .
Parameters (1)
- I
Index(L: TopLoc_Location): number
Returns the index of <L>.
Parameters (1)
- L

TopTools_ShapeSet

A ShapeSets contains a Shape and all its sub-shapes and locations. It can be dump, write and read.
Methods to handle the geometry can be redefined.

Constructors(1)

constructor(): TopTools_ShapeSet
Builds an empty ShapeSet.

Instance methods(13)

SetFormatNb(theFormatNb: number): void
Sets the TopTools_FormatVersion.
Parameters (1)
- theFormatNb
FormatNb(): number
Returns the TopTools_FormatVersion.
Clear(): void
Clears the content of the set. This method can be redefined.
Add(S: TopoDS_Shape): number
Stores and its sub-shape. Returns the index of . The method AddGeometry is called on each sub-shape.
Parameters (1)
- S
Shape(I: number): TopoDS_Shape
Returns the sub-shape of index .
Parameters (1)
- I
Index(S: TopoDS_Shape): number
Returns the index of .
Parameters (1)
- S
Locations(): TopTools_LocationSet
ChangeLocations(): TopTools_LocationSet
DumpExtent(S: TCollection_AsciiString): void
Dumps the number of objects in me on the stream <OS>. (Number of shapes of each type).
Parameters (1)
- S —
  Mutated in place; read the updated value from this argument after the call.
AddGeometry(S: TopoDS_Shape): void
Stores the geometry of .
Parameters (1)
- S
AddShapes(S1: TopoDS_Shape, S2: TopoDS_Shape): void
Inserts the shape <S2> in the shape <S1>. This method must be redefined to use the correct builder.
Parameters (2)
- S1 —
  Mutated in place; read the updated value from this argument after the call.
- S2
Check(T: TopAbs_ShapeEnum, S: TopoDS_Shape): void
This method is called after each new completed shape. <T> is the type. is the shape. In this class it does nothing, but it gives the opportunity in derived classes to perform extra treatment on shapes.
Parameters (2)
- T
- S —
  Mutated in place; read the updated value from this argument after the call.
NbShapes(): number
Returns number of shapes read from file.
