OpenCascade.jsTopLoc
OCCT package TopLoc: TopLoc_Datum3D, TopLoc_ItemLocation, TopLoc_Location, TopLoc_SListNodeOfItemLocation, and 1 more bound classes.
TopLoc_Datum3D
Describes a coordinate transformation, i.e. a change to an elementary 3D coordinate system, or position in 3D space. A Datum3D is always described relative to the default datum. The default datum is described relative to itself: its origin is (0,0,0), and its axes are (1,0,0) (0,1,0) (0,0,1).
Constructors(2)
Constructs a default Datum3D.
Constructs a Datum3D form a Trsf from gp. An error is raised if the Trsf is not a rigid transformation.
Parameters (1)T
Static methods(2)
- get_type_name(): string
Instance methods(4)
Returns a
gp_Trsfwhich, when applied to this datum, produces the default datum.Returns a
gp_Trsfwhich, when applied to this datum, produces the default datum.- Form(): gp_TrsfForm
Return transformation form.
TopLoc_ItemLocation
An ItemLocation is an elementary coordinate system in a Location.
The ItemLocation contains:
- The elementary Datum.
- The exponent of the elementary Datum.
- The transformation associated to the composition.
Constructors(1)
- constructor(D: TopLoc_Datum3D, P: number): TopLoc_ItemLocation
Sets the elementary Datum to <D> Sets the exponent to.
Parameters (2)DP
TopLoc_Location
A Location is a composite transition. It comprises a series of elementary reference coordinates, i.e. objects of type TopLoc_Datum3D, and the powers to which these objects are raised.
Constructors(4)
Constructs an empty local coordinate system object. Note: A Location constructed from a default datum is said to be "empty".
- constructor(theOther: TopLoc_Location): TopLoc_Location
Copy constructor.
Parameters (1)theOther
Move constructor.
Parameters (1)T
Constructs the local coordinate system object defined by the transformation T. T invokes in turn, a
TopLoc_Datum3Dobject.Parameters (1)D
Static methods(1)
- ScalePrec(): number
Instance methods(15)
- IsIdentity(): boolean
Returns true if this location is equal to the Identity transformation.
- Identity(): void
Resets this location to the Identity transformation.
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.
- FirstPower(): number
Returns the power elevation of the first elementary datum. Exceptions Standard_NoSuchObject if this location is empty.
Returns a Location representing <me> without the first datum. We have the relation:
<me> =NextLocation()*FirstDatum()^FirstPower()Exceptions Standard_NoSuchObject if this location is empty.Returns the transformation associated to the coordinate system.
Returns the inverse of <me>.
<me> *Inverted()is an Identity.- Multiplied(Other: TopLoc_Location): TopLoc_Location
Returns <me> * <Other>, the elementary datums are concatenated.
Parameters (1)Other
- Divided(Other: TopLoc_Location): TopLoc_Location
Returns <me> / <Other>.
Parameters (1)Other
- Predivided(Other: TopLoc_Location): TopLoc_Location
Returns <Other>.
Inverted()* <me>.Parameters (1)Other
- Powered(pwr: number): TopLoc_Location
Returns me at the power <pwr>. If <pwr> is zero returns Identity. <pwr> can be lower than zero (usual meaning for powers).
Parameters (1)pwr
- HashCode(): number
Returns a hashed value for this local coordinate system. This value is used, with map tables, to store and retrieve the object easily.
Returnsa computed hash code
- IsEqual(theOther: TopLoc_Location): boolean
Returns true if this location and the location Other have the same elementary data, i.e. contain the same series of
TopLoc_Datum3Dand respective powers. This method is an alias for operator ==.Parameters (1)theOther
- IsDifferent(theOther: TopLoc_Location): boolean
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_Datum3Dand respective powers. This method is an alias for operator !=.Parameters (1)theOther
- Clear(): void
Clear myItems.
TopLoc_SListNodeOfItemLocation

Static methods(2)

Instance methods(3)
TopLoc_SListOfItemLocation
An SListOfItemLocation is a LISP like list of Items. An SListOfItemLocation is: . Empty. . Or it has a Value and a Tail which is an other SListOfItemLocation.
The Tail of an empty list is an empty list. SListOfItemLocation are shared. It means that they can be modified through other lists. SListOfItemLocation may be used as Iterators. They have Next, More, and value methods. To iterate on the content of the list S just do.
SListOfItemLocation Iterator; for (Iterator = S; Iterator.More(); Iterator.Next()) X = Iterator.Value();
Constructors(3)
Creates an empty List.
Creates a list from an other one. The lists are shared.
Parameters (1)Other
- constructor(anItem: TopLoc_ItemLocation, aTail: TopLoc_SListOfItemLocation): TopLoc_SListOfItemLocation
Creates a List with <anItem> as value and <aTail> as tail.
Parameters (2)anItemaTail
Instance methods(9)
Sets a list from an other one. The lists are shared. The list itself is returned.
Parameters (1)Other
- IsEmpty(): boolean
Return true if this list is empty.
- Clear(): void
Sets the list to be empty.
Returns the current value of the list. An error is raised if the list is empty.
Returns the current tail of the list. On an empty list the tail is the list itself.
- Construct(anItem: TopLoc_ItemLocation): void
Replaces the list by a list with <anItem> as Value and the list <me> as tail.
Parameters (1)anItem
- ToTail(): void
Replaces the list <me> by its tail.
- More(): boolean
Returns True if the iterator has a current value. This is !IsEmpty().
- Next(): void
Moves the iterator to the next object in the list. If the iterator is empty it will stay empty. This is
ToTail().
