Detailed Description

The dimeTableEntry class is the superclass for all table classes.


Constructor & Destructor Documentation

dimeTableEntry::dimeTableEntry  
 

Constructor.

dimeTableEntry::~dimeTableEntry   [virtual]
 

Destructor.


Member Function Documentation

bool dimeTableEntry::copyRecords dimeTableEntry *const    table,
dimeModel *const    model
const [protected]
 

Copies the unclassified records.

int dimeTableEntry::countRecords   const [virtual]
 

Returns the number of records for this table. Tables overloading this function should first count the number of records they will write, then add the return value of this function to get the total number of records.

Reimplemented from dimeRecordHolder.

Reimplemented in dimeLayerTable, dimeUCSTable, and dimeUnknownTable.

dimeTableEntry * dimeTableEntry::createTableEntry const char *const    name,
dimeMemHandler *const    memhandler = NULL
[static]
 

Static function that creates a table based on its name.

bool dimeTableEntry::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 \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 dimeRecordHolder.

Reimplemented in dimeLayerTable, and dimeUCSTable.

bool dimeTableEntry::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 dimeTableEntry::read dimeInput *const    file [virtual]
 

Reads records from in until the separator groupcode (specified in constructor) is found. Can be overloaded by subclasses, but in most cases this will not be necessary as dimeRecordHolder::handleRecord() is called for each record found in the stream.

See also:
dimeEntity::handleRecord().

Reimplemented from dimeRecordHolder.

Reimplemented in dimeLayerTable.

int dimeTableEntry::typeId   const [pure virtual]
 

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

Reimplemented from dimeBase.

Reimplemented in dimeLayerTable, dimeUCSTable, and dimeUnknownTable.

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

Will write the records to file.

Reimplemented from dimeRecordHolder.

Reimplemented in dimeLayerTable, dimeUCSTable, and dimeUnknownTable.
