類別com.UniPRT.Sdk.Comm.BTClassicConnection的繼承圖:

公開方法(Public Methods)
	BTClassicConnection (String descriptor)
	根據 descriptor 字串初始化新實例。更多...

	BTClassicConnection (long bt_address)
	根據 macAddress 初始化新實例。需先與印表機進行藍牙配對後才能連線。更多...

int	BytesAvailable ()

String	Descriptor ()

boolean	Connected ()

void	Close ()

void	Open ()

byte[]	Read ()

void	Write (byte[] dataOut)

公開方法(Public Methods) 繼承自 com.UniPRT.Sdk.Comm.AComm
void	Read (OutputStream binDataIn) throws IOException

void	WaitForData (int msTimeOut)
	等待當前執行緒有可用的資料 BytesAvailable。當前執行緒會休眠直到收到資料或超時為止。此為阻塞呼叫。更多...

void	Write (InputStream binReader) throws IOException
	從輸入流寫入輸出流。更多...

void	WriteAndWaitForResponse (OutputStream binDataIn, InputStream binDataOut, int responseStartTimeOut, int responseEndTimeOut, String completetionToken) throws IOException
	將 binDataOut 流資料寫入輸出流，並將接收到的資料返回到 binDataIn 流中。返回的資料是收到的資料或收到的完成標記。等待回應超時後返回。更多...

byte[]	WriteAndWaitForResponse (byte[] dataOut, int responseStartTimeOut, int responseEndTimeOut, String completetionToken) throws IOException
	將位元組資料寫入輸出流並返回接收到的資料。返回的資料是接收到的任何資料或收到的完成標記。等待回應超時後返回。更多...

靜態公開方法(Static Public Methods)
static long	DescriptorValidate (String descriptorHint)
	從 descriptorHint 驗證描述字串是否有效，可能包含或不包含 v_id 與 p_id。返回 long 值。更多...
