Member Function Documentation

◆ getAllowedPropertyKeys()

virtual const char** getAllowedPropertyKeys ( ) const

overrideprotectedvirtual

Returns the list of allowed keys in @figure properties with this figure type, in a nullptr-terminated array of const char* elements. This method is invoked e.g. from parse(), in order to be able to issue error messages for invalid keys in the property. Note that property keys starting with "x-" are already allowed by default. Custom figure classes usually need to override this method together with parse(); see the source code of the library classes for example implementations.

Reimplemented from cAbstractLineFigure.

◆ dup()

virtual cLineFigure* dup ( ) const

inlineoverridevirtual

Clones the figure, ignoring its child figures. (The copy will have no children.) To clone a figure together with its figure subtree, use dupTree().

Reimplemented from cAbstractLineFigure.

◆ str()

virtual std::string str ( ) const

overridevirtual

Returns a one-line string with the most characteristic data of the figure.

Reimplemented from cAbstractLineFigure.

◆ parse()

virtual void parse ( cProperty * property )

overridevirtual

This method is invoked by the simulation library to initialize the figure from a @figure NED property. Custom figure classes usually need to override this method (and call the super class' similar method in it).

Note: When overriding parse(), it is usually also necessary to override getAllowedPropertyKeys(), in order to allow new keys in the @figure property.

Reimplemented from cAbstractLineFigure.

◆ moveLocal()

virtual void moveLocal	(	double	dx,
		double	dy
	)

overridevirtual

Change the figure's position by the given x and y deltas. Child figures will not be affected.

Implements cFigure.

◆ getRendererClassName()

virtual const char* getRendererClassName ( ) const

inlineoverridevirtual

Returns the name of the class responsible for rendering this figure. Renderer classes are specific to, and are usually implemented as part of, the graphical user interface library e.g. Qtenv.

Implements cFigure.

◆ getStart()

virtual const Point& getStart ( ) const

inlinevirtual

Returns the start point of the line segment.

◆ setStart()

virtual void setStart ( const Point & start )

virtual

Sets the start point of the line segment.

◆ getEnd()

virtual const Point& getEnd ( ) const

inlinevirtual

Returns the end point of the line segment.

◆ setEnd()

virtual void setEnd ( const Point & end )

virtual

Sets the end point of the line segment.
