Detailed Description

This package gives resources for Topology oriented applications such as : Topological Data Structure, Topological Algorithms.

It contains :

The ShapeEnum enumeration to describe the differents topological shapes.
The Orientation enumeration to describe the orientation of a topological shape.
The State enumeration to describes the position of a point relative to a Shape.
Methods to manage the enumerations.

Member Function Documentation

◆ Complement()

static TopAbs_Orientation TopAbs::Complement ( const TopAbs_Orientation Or )

static

Reverses the interior/exterior status of each side of the object. So, to take the complement of an object means to reverse the interior/exterior status of its boundary, i.e. inside becomes outside. The method returns the complementary orientation, following the rules in the table below: FORWARD REVERSED REVERSED FORWARD INTERNAL EXTERNAL EXTERNAL INTERNAL.

Complement complements the material side. Inside becomes outside.

◆ Compose()

static TopAbs_Orientation TopAbs::Compose	(	const TopAbs_Orientation	Or1,
		const TopAbs_Orientation	Or2
	)

static

Compose the Orientation <Or1> and <Or2>. This composition is not symmetric (if you switch <Or1> and <Or2> the result is different). It assumes that <Or1> is the Orientation of a Shape S1 containing a Shape S2 of Orientation Or2. The result is the cumulated orientation of S2 in S1. The composition law is :

\ Or2 FORWARD REVERSED INTERNAL EXTERNAL Or1 ----------------------------------— FORWARD | FORWARD REVERSED INTERNAL EXTERNAL | REVERSED | REVERSED FORWARD INTERNAL EXTERNAL | INTERNAL | INTERNAL INTERNAL INTERNAL INTERNAL | EXTERNAL | EXTERNAL EXTERNAL EXTERNAL EXTERNAL Note: The top corner in the table is the most important for the purposes of Open CASCADE topology and shape sharing.

◆ Print() [1/3]

static Standard_OStream& TopAbs::Print	(	const TopAbs_ShapeEnum	theShapeType,
		Standard_OStream &	theStream
	)

inlinestatic

Prints the name of Shape type as a String on the Stream.

◆ Print() [2/3]

static Standard_OStream& TopAbs::Print	(	const TopAbs_Orientation	theOrientation,
		Standard_OStream &	theStream
	)

inlinestatic

Prints the name of the Orientation as a String on the Stream.

◆ Print() [3/3]

static Standard_OStream& TopAbs::Print	(	const TopAbs_State	St,
		Standard_OStream &	S
	)

static

Prints the name of the State <St> as a String on the Stream <S> and returns <S>.

◆ Reverse()

static TopAbs_Orientation TopAbs::Reverse ( const TopAbs_Orientation Or )

static

xchanges the interior/exterior status of the two sides. This is what happens when the sense of direction is reversed. The following rules apply:

FORWARD REVERSED REVERSED FORWARD INTERNAL INTERNAL EXTERNAL EXTERNAL

Reverse exchange the material sides.

◆ ShapeOrientationToString()

static Standard_CString TopAbs::ShapeOrientationToString ( TopAbs_Orientation theOrientation )

static

Returns the string name for a given shape orientation.

Parameters

theOrientation shape orientation

Returns: string identifier from the list FORWARD, REVERSED, INTERNAL, EXTERNAL

◆ ShapeTypeFromString() [1/2]

static TopAbs_ShapeEnum TopAbs::ShapeTypeFromString ( Standard_CString theTypeString )

inlinestatic

Returns the shape type from the given string identifier (using case-insensitive comparison).

Parameters

theTypeString string identifier

Returns: shape type or TopAbs_SHAPE if string identifier is invalid

◆ ShapeTypeFromString() [2/2]

static Standard_Boolean TopAbs::ShapeTypeFromString	(	Standard_CString	theTypeString,
		TopAbs_ShapeEnum &	theType
	)

static

Determines the shape type from the given string identifier (using case-insensitive comparison).

Parameters

theTypeString	string identifier
theType	detected shape type

Returns: TRUE if string identifier is known

◆ ShapeTypeToString()

static Standard_CString TopAbs::ShapeTypeToString ( TopAbs_ShapeEnum theType )

static

Returns the string name for a given shape type.

Parameters

theType shape type

Returns: string identifier from the list COMPOUND, COMPSOLID, SOLID, SHELL, FACE, WIRE, EDGE, VERTEX, SHAPE
