Detailed Description

A base class that implements storing and handling data about a definition of an IfcCurve.

Definition at line 47 of file IfcCurve.h.

Member Function Documentation

entityId()

virtual OdGe::EntityId OdIfc::OdIfcCurve::entityId ( ) const

inlinevirtual

Retrieves the identifier of an underlying Ge curve.

Returns

An <exref target="OdGe::EntityId"></exref> object that contains the underlaying Ge curve identifier.

Definition at line 59 of file IfcCurve.h.

evalPoint()

virtual OdGePoint3d OdIfc::OdIfcCurve::evalPoint ( double param, OdGeVector3dArray & derivs ) const

virtual

Calculates position and first derivative of the curve by parameter value.

Parameters

param	[in] Parameter value.
derivs	[out] An OdGeVector3dArray which contains first derivative of the curve in parameter.

Returns

Position on the curve as OdGePoint3d instance.

Reimplemented in OdIfc::OdIfcGradientCurve.

getGeCurve()

const OdGeCurve3d * OdIfc::OdIfcCurve::getGeCurve ( ) const

inline

Retrieves the underlaying Ge curve object in read-only mode.

Returns

A constant raw pointer to the underlying Ge curve represented with an <exref target="OdGeCurve3d.html">OdGeCurve3d</exref> object.

Definition at line 71 of file IfcCurve.h.

getGeCurveCopy()

virtual OdGeCurve3d * OdIfc::OdIfcCurve::getGeCurveCopy ( ) const

inlinevirtual

Returns a copy of the underlying Ge curve.

Returns

A raw pointer to the <exref target="OdGeCurve3d.html">OdGeCurve3d</exref> object that represents the copy of the underlaying Ge curve.

Definition at line 65 of file IfcCurve.h.

getMatrix()

void OdIfc::OdIfcCurve::getMatrix ( OdIfcInstancePtr pPosition, OdGeMatrix3d & matr )

protected

is3d()

virtual bool OdIfc::OdIfcCurve::is3d ( ) const

inlinevirtual

Defines whether the curve is a 3D object.

Returns

true if the curve is a 3D object; otherwise, the method returns false.

Reimplemented in OdIfc::OdIfcCompositeCurve.

Definition at line 99 of file IfcCurve.h.

paramAtLength()

virtual double OdIfc::OdIfcCurve::paramAtLength ( double length ) const

virtual

Retrieves parameter value by provided curve length.

Parameters

length

[in] Length from the curve start.

Returns

Parameter value along the curve.

Reimplemented in OdIfc::OdIfcGradientCurve.

setIs3d()

void OdIfc::OdIfcCurve::setIs3d ( bool val )

inline

Sets a new value of the 3D flag for the curve. 3D flag determines whether the curve is a 3D object (if it equals true) or not (in this case the flag value equals false).

Parameters

val	[in] A new value of the flag to be set.

Definition at line 106 of file IfcCurve.h.

transformBy()

OdResult OdIfc::OdIfcCurve::transformBy ( const OdGeMatrix3d & transform )

overridevirtual

Applies the specified transformation to the object.

Parameters

transform

[in] A transformation matrix to be applied.

Returns

eOk value if the transformation operation was successful; otherwise, the method returns an appropriate error code.

Reimplemented from OdIfc::OdIfcRepresentationItem.
