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.

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.

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;

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
[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 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::setRecord()

Reimplemented from dimeEntity.

int dimeVertex::numIndices  )  const
 

Returns the number of indices stored in this vertex;

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]
 

Will write the records to file.

Reimplemented from dimeEntity.
