Detailed Description

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.

Constructor & Destructor Documentation

◆ TopLoc_Location() [1/3]

TopLoc_Location::TopLoc_Location ( )

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

◆ TopLoc_Location() [2/3]

TopLoc_Location::TopLoc_Location ( const gp_Trsf & T )

Constructs the local coordinate system object defined by the transformation T. T invokes in turn, a TopLoc_Datum3D object.

◆ TopLoc_Location() [3/3]

TopLoc_Location::TopLoc_Location ( const Handle< TopLoc_Datum3D > & D )

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.

◆ FirstDatum()

const Handle< TopLoc_Datum3D > & TopLoc_Location::FirstDatum ( ) const

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.

Standard_Integer TopLoc_Location::FirstPower ( ) const

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