property thisown

The membership flag

class TopLoc_Location(*args)

Bases: object

• Constructs an empty local coordinate system object. Note: A Location constructed from a default datum is said to be ‘empty’.

  rtype

  None* Constructs the local coordinate system object defined by the transformation T. T invokes in turn, a TopLoc_Datum3D object.

  param T

  type T

  gp_Trsf

  rtype

  None* Constructs the local coordinate system object defined by the 3D datum D. Exceptions Standard_ConstructionError if the transformation T does not represent a 3D coordinate system.

  param D

  type D

  TopLoc_Datum3D

  rtype

  None

Divided()

• Returns <self> / <Other>.

  param Other

  type Other

  TopLoc_Location

  rtype

  TopLoc_Location

DumpJsonToString(TopLoc_Location self, int depth=-1) → std::string

FirstDatum()

• Returns the first elementary datum of the Location. Use the NextLocation function recursively to access the other data comprising this location. Exceptions Standard_NoSuchObject if this location is empty.

  rtype

  opencascade::handle<TopLoc_Datum3D>

FirstPower()

• Returns the power elevation of the first elementary datum. Exceptions Standard_NoSuchObject if this location is empty.

  rtype

  int

HashCode()

• Returns a hashed value for this local coordinate system. This value is used, with map tables, to store and retrieve the object easily, and is in the range [1, theUpperBound]. @param theUpperBound the upper bound of the range a computing hash code must be within returns a computed hash code, in the range [1, theUpperBound]

  param theUpperBound

  type theUpperBound

  int

  rtype

  int

Identity()

• Resets this location to the Identity transformation.

  rtype

  None

Inverted()

• Returns the inverse of <self>. //! <self> * Inverted() is an Identity.

  rtype

  TopLoc_Location

IsDifferent()

• Returns true if this location and the location Other do not have the same elementary data, i.e. do not contain the same series of TopLoc_Datum3D and respective powers. This method is an alias for operator !=.

  param Other

  type Other

  TopLoc_Location

  rtype

  bool

IsEqual()

• Returns true if this location and the location Other have the same elementary data, i.e. contain the same series of TopLoc_Datum3D and respective powers. This method is an alias for operator ==.

  param Other

  type Other

  TopLoc_Location

  rtype

  bool

IsIdentity()

• Returns true if this location is equal to the Identity transformation.

  rtype

  bool

Multiplied()

• Returns <self> * <Other>, the elementary datums are concatenated.

  param Other

  type Other

  TopLoc_Location

  rtype

  TopLoc_Location

NextLocation()

• Returns a Location representing <self> without the first datum. We have the relation//! <self> = NextLocation() * FirstDatum() ^ FirstPower() Exceptions Standard_NoSuchObject if this location is empty.

  rtype

  TopLoc_Location

Powered()

• Returns me at the power <pwr>. If <pwr> is zero returns Identity. <pwr> can be lower than zero (usual meaning for powers).

  param pwr

  type pwr

  int

  rtype

  TopLoc_Location

Predivided()

• Returns <Other>.Inverted() * <self>.

  param Other
