Key actions include: connecting (`connect`, `connect_`), disconnecting (`disconnect`, `disconnectInternal`) and reconnecting blocks (`reconnect`). It manages connection compatibility (`getCheck`, `setCheck`), determines connection status (`isConnected`, `isSuperior`), and provides methods to manage shadow blocks (`getShadowDom`, `setShadowDom`, `respawnShadow_`). The class also defines constants for connection compatibility checks, providing reason codes. Methods exist to get block targets (`targetBlock`, `getSourceBlock`).\n"]]
