Detailed Description

The dimeVertex class handles a VERTEX entity.

Constructor & Destructor Documentation

dimeVertex::dimeVertex ( )

Constructor.

Member Function Documentation

dimeEntity * dimeVertex::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.

References dimeEntity::copyRecords(), and dimeModel::getMemHandler().

int dimeVertex::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.

References dimeEntity::isDeleted(), and numIndices().

Referenced by dimePolyline::countRecords().

const char * dimeVertex::getEntityName ( ) const
virtual

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

Implements dimeEntity.

int dimeVertex::getIndex ( const int  num) const

Returns index number num;

Referenced by dimePolyline::extractGeometry().

bool dimeVertex::getRecord ( const int  groupcode,
dimeParam param,
const int  index = 0 
) 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 dimeVertex::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 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.

int dimeVertex::numIndices ( ) const

Returns the number of indices stored in this vertex;

Referenced by countRecords(), dimePolyline::extractGeometry(), dimePolyline::read(), and write().

int dimeVertex::typeId ( ) const
virtual

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

Implements dimeBase.

bool dimeVertex::write ( dimeOutput *const  file)
virtual
