Ccl class
This class defines enumerations which are used by other classes—both
ECI and EPI.
CclBuf class
A CclBuf object contains
a data area in memory that can be used to hold information. A particular
use for a CclBuf object is to hold a COMMAREA, which passes data to
and from a CICS® server.
CclConn class
An object of class CclConn is used to represent an ECI connection
between a client and a named server.
CclECI class
One instance only of the CclECI class can exist. It is
created by the instance class method. It controls the client interface
to the available servers.
CclEPI class
The CclEPI class initializes and terminates the CICS Transaction Gateway EPI
function. It also has methods which allow you to obtain information about CICS servers
configured in the CICS Transaction Gateway initialization file. You must create one object of
this class for each application process before you create CclTerminal objects
to connect to CICS servers.
CclException class
A CICS Transaction Gateway object constructs
an object of the CclException class if it encounters a problem.
CclField class
An object of the CclField class is responsible
for looking after a single field on a 3270 screen. CclField objects are created and deleted when 3270 data from the CICS server
is processed by a CclScreen object.
CclFlow class
A CclFlow object is used to control ECI communications
for a client/server pair and to determine the synchronization of reply
processing.
CclMap class
The CclMap class is a base class for map classes
created by the CICS BMS Map Conversion Utility. The methods provided by CclMap class are inherited by the classes generated from
BMS maps.
CclScreen class
The CclScreen EPI class maintains all data on
the 3270 virtual screen and provides access to this data. It contains a collection
of CclField objects which represent the fields on the current 3270 screen.
CclSecAttr
The CclSecAttr class provides information about passwords reported back
by the external security manager when verifyPassword or changePassword methods
are issued on CclConn or CclTerminal objects.
CclSecTime
The CclSecTime class provides date and time information in the CclSecAttr
object for various entries reported back by the external security manager
when verifyPassword or changePassword methods are issued on CclConn or CclTerminal
objects.
CclSession class
The CclSession class
allows the programmer to implement reusable code to handle a segment (one
or more transmissions) of a 3270 conversation. In multi-threaded environments
it provides asynchronous handling of replies from CICS.
CclTerminal class
An object of class CclTerminal represents a 3270
terminal connection to a CICS server. A CICS connection is established
when the object is created. Methods can then be used to converse with a 3270
terminal application (often a BMS application) in the CICS server.
CclUOW class
Use this ECI class when you make updates to recoverable resources in the
server within a “unit of work” (UOW).
