## Detailed Description

The dimeLayerTable class reads and writes LAYER tables.

## Constructor & Destructor Documentation

## ◆ dimeLayerTable()

dimeLayerTable::dimeLayerTable | ( |  | ) |

Constructor.

References dimeModel::addLayer(), dimeTableEntry::copyRecords(), and dimeModel::getMemHandler().

## Member Function Documentation

## ◆ countRecords()

int dimeLayerTable::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 dimeTableEntry.

References dimeTableEntry::countRecords().

## ◆ getColorNumber()

int16 dimeLayerTable::getColorNumber | ( | void |  | ) | const

Returns the color number.

## ◆ getLayerName()

const char * dimeLayerTable::getLayerName | ( | void |  | ) | const

Returns the layer name.

## ◆ handleRecord()

bool dimeLayerTable::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.

See also
  dimeRecordHolder::read()
  dimeRecordHolder::setRecord()

Reimplemented from dimeTableEntry.

References dimeTableEntry::handleRecord(), setColorNumber(), and setLayerName().

## ◆ read()

bool dimeLayerTable::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 dimeTableEntry.

References dimeInput::getModel(), dimeTableEntry::read(), and registerLayer().

## ◆ registerLayer()

void dimeLayerTable::registerLayer | ( | dimeModel * | model | ) |

Should be called once after you've finished setting up your layer (name and color number). Calling this method more than once for a layer might lead to hard-to-find bugs. After calling this method, the layer information (color number) will be available to entities using this layer.

References dimeModel::addLayer().

Referenced by read().

## ◆ setColorNumber()

void dimeLayerTable::setColorNumber | ( | const int16 | colnum | ) |

Sets the color number.

References dimeLayer::setColorNumber().

Referenced by handleRecord().

## ◆ setLayerName()

void dimeLayerTable::setLayerName | ( | const char * | name,
|  | dimeMemHandler *const | memhandler
| ) |  |

Sets the layer name.

Referenced by handleRecord().

## ◆ typeId()

int dimeLayerTable::typeId | ( |  | ) | const

virtual

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

Implements dimeTableEntry.

## ◆ write()

bool dimeLayerTable::write | ( | dimeOutput *const | file | ) |

virtual

Will write the records to file.

Reimplemented from dimeTableEntry.

References dimeTableEntry::write(), dimeOutput::writeGroupCode(), dimeOutput::writeInt16(), and dimeOutput::writeString().

Referenced by dimeTablesSection::read().
