Detailed Description

The dimeSpline class handles a SPLINE entity.


Constructor & Destructor Documentation

dimeSpline::dimeSpline  
 

Constructor.

dimeSpline::~dimeSpline   [virtual]
 

Destructor.


Member Function Documentation

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.

Reimplemented from dimeEntity.

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.

const char * dimeSpline::getEntityName   const [virtual]
 

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

Reimplemented from dimeEntity.

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.

bool dimeSpline::handleRecord const int    groupcode,
const dimeParam   param,
dimeMemHandler *const    mh
[protected, virtual]
 

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.

dimeRecordHolder::read() , dimeRecordHolder::setRecord()

Reimplemented from dimeEntity.

bool dimeSpline::hasWeights   const
 

Returns true if the spline has control point weights.

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.

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

Sets the weight of control point idx.

int dimeSpline::typeId   const [virtual]
 

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

Reimplemented from dimeBase.

bool dimeSpline::write dimeOutput *const    file [virtual]
 

Will write the records to file.

Reimplemented from dimeEntity.
