Table 3-2 List of APIs (methods)

Classification	Method	Description or function
Execution	acceptNotification(byte[] inf,int[] inf_len,int port,int timeout,byte[] hostname,byte[] nodeid)	Receives messages that are sent by server's function (dc_rpc_cltsend function).
	acceptNotificationChained(byte[] inf,int[] inf_len,int timeout,byte[] hostname,byte[] nodeid)
	cancelNotification(byte[] inf,int inf_len,String hostname,int port)	Releases the unidirectional server message reception wait status (issuance of the acceptNotification or acceptNotificationChained method).
	closeConnection()	Releases a permanent connection between a CUP and a RAP-processing listener and server.
	closeNotification()	Deletes an environment for using the unidirectional message consecutive reception facility.
	cltAssemSend(byte[] buff, int sendleng, String hostname, int portnum, int timeout, int flags)	Uses the receive message assembly facility to send a message.
	cltAssemReceive(byte[] buff, int[] recvleng, int timeout, int flags)	Uses the receive message assembly facility to receive a message.
	closeConnection()	Releases a permanent connection between a CUP and a RAP-processing listener and server.
	cltReceive(byte[] buff, int[] recvleng, int timeout, int flags)	Receives a message sent by an MHP.
	cltSend(byte[] buff, int sendleng, String hostname, int portnum, int flags)	Sends a message to an MHP.
	getTrnID(byte[] gid, byte[] bid)	Obtains the transaction global identifier and transaction branch identifier.
	openConnection()	Establishes a permanent connection with a RAP-processing server or connects to TP1/Web and starts a virtual session.
	openConnection(String host, int port)
	openConnection(String url, short flags)
	openNotification(int port)	Creates an environment for using the unidirectional message consecutive reception facility.
	rpcCall(String group, String service, byte[] in_data, int[] in_len, byte[] out_data, int[] out_len, int flags)	Issues an RPC to the specified service-group-name + service-name.
	rpcCall(String group, String service, byte[] in_data, byte[] out_data, int flags)
	rpcCallTo(DCRpcBindTbl direction, String group, String service, byte[] in_data, int[] in_len, byte[] out_data, int[] out_len, int flags)	Issues an RPC to the service-group-name + service-name of the specified communication-target node.
	rpcClose()	Releases the environment for calling a TP1/Server SPP.
	rpcOpen()	Initializes the environment for calling a TP1/Server SPP.
	rpcOpen(String deffilename)
	trnBegin()	Starts a global transaction.
	trnChainedCommit()	Acquires the synchronization point of a transaction.
	trnChainedRollback()	Rolls back a transaction.
	trnInfo()	Determines whether or not the TP1Client object is running as a transaction.
	trnUnchainedCommit()	Acquires the synchronization point of a transaction.
	trnUnchainedRollback()	Rolls back a transaction.
Definition	setConnectInformation(byte[] inf, short inf_len)	Sets terminal identification information.
	setDataTraceMode(String TrcPath, int size, int Datasize, boolean flag)#	Specifies whether or not to output to a file a data trace when an RPC is issued from a Java application or servlet.
	setDccltdelay(int sec)	Sets the communication delay time between a CUP and a RAP-processing listener and server.
	setDccltextend(int flags)	Sets the extension level of the TP1/Client/J facility. The user can specify multiple extension levels by specifying the disjunction of each value.
	setDccltinquiretime(int sec)	Sets the maximum time for the inquiry interval that is monitored from the RAP-processing server (if no service request is received from the client within this period, the connection is released).
	setDchost(String host, int port)	Sets the host name and port number of the TP1/Server as a gateway.
	setDcselint(int msec)	This method serves no purpose. It is retained only to provide compatibility with the source of the previous version.
	setDcwatchtim(int sec)	For a synchronous-response RPC, sets the maximum time to wait for a response from the service since a service request was issued from the CUP to the SPP.
	setErrorTraceMode(String TrcPath, int size, boolean flag)#	Specifies whether or not to output to a file information about connection establishment with the server, disconnection from the server, and error trace when the TP1Client class is called from a Java application or servlet.
	setMethodTraceMode(String TrcPath, int size, boolean flag)#	Specifies whether or not to output to a file a method trace when the TP1Client class is called from a Java application or servlet.
	setRpcextend(int extendoption)	Changes RPC-related settings.
	setScdDirectObject(String scdhost, int scdport, int flags)	Sets the host name and port number of the communication-target scheduler.
	setTraceArray(String[] array)	Specifies the array (memory trace) for storing information about connection establishment with the server, disconnection from the server, and error trace when the TP1Client class is called from a Java application, servlet, or applet. To view the error information, you must use a Java application, servlet, or applet to reference the contents of this array.
	setUapTraceMode(String TrcPath, int size, boolean flag)#	Specifies whether or not to output to a file a UAP trace when the TP1Client class is called from a Java application or servlet.

Only Java applications and servlets can use this method. If an attempt is made to use this method with a Java applet, SecurityException occurs.
