Member Function Documentation

bool dimeObject::copyRecords dimeObject *const  myobject,
dimeModel *const  model
const [protected]
 

Copies the common and unobjectified records.

int dimeObject::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 dimeRecordHolder.

Reimplemented in dimeUnknownObject.

dimeObject * dimeObject::createObject const char *const  name,
dimeMemHandler *const  memhandler = NULL
[static]
 

Static function which creates an object based on its name.

bool dimeObject::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::read()

dimeRecordHolder::setRecord()

Reimplemented from dimeRecordHolder.

bool dimeObject::isOfType const int  thetypeid  )  const [virtual]
 

Returns true if the object is of type typeid or is inherited from it. Function in base class checks whether thetypeid equals the virtual dimeBase::typeId() value or equals dimeBaseType. Must be implemented by all subclasses that are superclasses of other classes, and should check if thetypeid equals its typeId, and then call its parent's isOfType function. Leaf-classes do not have to implement this method.

Reimplemented from dimeRecordHolder.

bool dimeObject::read dimeInput *const  file  )  [virtual]
 

Reads an object from in. Can be overloaded by subobjects, but in most cases this will not be necessary.

See also:
dimeObject::handleRecord().

Reimplemented from dimeRecordHolder.

int dimeObject::typeId  )  const [pure virtual]
 

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

Implements dimeBase.

Implemented in dimeUnknownObject.

bool dimeObject::write dimeOutput *const  file  )  [virtual]
 

Writes common and unknown object records to file.

Reimplemented from dimeRecordHolder.

Reimplemented in dimeUnknownObject.
