Detailed Description

The dimeSpline class handles a SPLINE entity.

Constructor & Destructor Documentation

◆ dimeSpline()

dimeSpline::dimeSpline ( )

Constructor.

◆ ~dimeSpline()

dimeSpline::~dimeSpline ( )

virtual

Destructor.

Member Function Documentation

◆ hasWeights()

bool dimeSpline::hasWeights ( ) const

Returns true if the spline has control point weights.

◆ setControlPoints()

void dimeSpline::setControlPoints	(	const dimeVec3f *const	pts,
		const int	numpts,
		dimeMemHandler *const	memhandler = `NULL`
	)

Sets new control points for this spline. It is the user's responsibility to update the weights whenever the control point are changed.

◆ setWeight()

void dimeSpline::setWeight	(	const int	idx,
		const dxfdouble	w,
		dimeMemHandler *const	memhandler = `NULL`
	)

Sets the weight of control point idx.

◆ copy()

dimeEntity * dimeSpline::copy ( dimeModel *const model ) const

virtual

Must be implemented by subclasses to return a copy of the entity. model is the model the new entity should belong to.

Implements dimeEntity.

◆ getRecord()

bool dimeSpline::getRecord	(	const int	groupcode,
		dimeParam &	param,
		const int	index
	)		const

virtual

Will return the value of the record with group code groupcode. false is returned if the record could not be found. Subclasses should overload this method if one or several records are stored in the class. If the groupcode queried is not stored internally, the subclass should call its parent's method.

Reimplemented from dimeEntity.

◆ getEntityName()

const char * dimeSpline::getEntityName ( ) const

virtual

Must be implemented by subclasses to return the entity name; e.g. POLYLINE, 3DFACE, etc.

Implements dimeEntity.

◆ write()

bool dimeSpline::write ( dimeOutput *const file )

virtual

Will write the records to file.

Reimplemented from dimeEntity.

◆ typeId()

int dimeSpline::typeId ( ) const

virtual

Must be implemented by all subclasses, and should return an unique id for that class.

Implements dimeBase.

◆ countRecords()

int dimeSpline::countRecords ( ) const

virtual

Returns the number of records in the record holder. Should be overloaded by subclasses which should count their records, and then call the parent's method. This method is used to precalculate the number of records to be written. Very useful when progress information is needed during write().

Reimplemented from dimeEntity.

◆ handleRecord()

bool dimeSpline::handleRecord	(	const int	groupcode,
		const dimeParam &	param,
		dimeMemHandler *const	memhandler
	)

protectedvirtual

Must be overloaded by entities that directly supports a record type. During dimeRecordHolder::read(), dimeRecordHolder::setRecord and dimeRecordHolder::setRecords, this function is called for every record found, and it is up to the subclass if the record should be stored internally, or if a generic record should be created and stored in this superclass. A subclass should return true when it will handle the record, false otherwise. Default function does nothing, and returns false.

For entities, records with group codes 8 (layer name) and 62 (color number) are automatically handled by the dimeEntity class.
