"@brief The basic class for implementing custom device extractors.\n"
"\n"
"This class serves as a base class for implementing customized device extractors. "
"This class does not provide any extraction functionality, so you have to "
"implement every detail.\n"
"\n"
"Device extraction requires a few definitions. The definitions are made in the reimplementation of the \\setup\n"
"method. Required definitions to be made are:\n"
"\n"
"@ul\n"
" @li The name of the extractor. This will also be the name of the device class produced by the extractor. "
" The name is set using \\name=. @/li\n"
" @li The device class of the devices to produce. The device class is registered using \\register_device_class. @/li\n"
" @li The layers used for the device extraction. These are input layers for the extraction as well as "
" output layers for defining the terminals. Terminals are the points at which the nets connect to the devices.\n"
" Layers are defined using \\define_layer. Initially, layers are abstract definitions with a name and a description.\n"
" Concrete layers will be given when defining the connectivity. @/li\n"
"@/ul\n"
"\n"
"When the device extraction is started, the device extraction algorithm will first ask the device extractor "
"for the 'connectivity'. This is not a connectivity in a sense of electrical connections. The connectivity defines are "
"logical compound that makes up the device. 'Connected' shapes are collected and presented to the device extractor.\n"
"The connectivity is obtained by calling \\get_connectivity. This method must be "
"implemented to produce the connectivity.\n"
"\n"
"Finally, the individual devices need to be extracted. Each cluster of connected shapes is presented to the "
"device extractor. A cluster may include more than one device. It's the device extractor's responsibility to "
"extract the devices from this cluster and deliver the devices through \\create_device. In addition, terminals "
"have to be defined, so the net extractor can connect to the devices. Terminal definitions are made through "
"\\define_terminal. The device extraction is implemented in the \\extract_devices method.\n"
"\n"
"If errors occur during device extraction, the \\error method may be used to issue such errors. Errors "
"reported this way are kept in the error log.\n"
