示例1: setValue
/**
* Set the value of this field in various formats.
* Used by {@link DataObject->getField()}, {@link DataObject->setCastedField()}
* {@link DataObject->dbObject()} and {@link DataObject->write()}.
*
* As this method is used both for initializing the field after construction,
* and actually changing its values, it needs a {@link $markChanged}
* parameter.
*
* @param DBField|array $value
* @param array $record Map of values loaded from the database
* @param boolean $markChanged Indicate wether this field should be marked changed.
* Set to FALSE if you are initializing this field after construction, rather
* than setting a new value.
