The importers
Importers bring source code or artifacts into your development
environment.
Overview
The section introduces the service flow project tools.
Working with service flow projects
A service flow project is a structural container for the
various types of artifacts that you can create with the service flow project
tools.
Working with host connections
A host connection has the extension .host (for example, system.host) and is displayed in the Hosts folder of a terminal applications subproject in your service flow project.
Importing resources
Importers are a set of components used to populate parts of the
information model from existing resources. These resources may be data format
definitions for messages or control blocks used by host applications, screen
format definitions, for either entire screens or parts of screens, or
captures of actual screens.
Working with screen messages
The service flow project tools uses screen messages to
detect and to read from or write into the various individual application screens
that occur in a terminal application.
Working with screen operations files
A screen operations file is a container for screen operations. A screen operation is an artifact that contains the information required to control a particular application screen in a terminal application.
Working with messages
A message is a set of data that is passed
from one application to another. A message can be modeled by a message
file that describes the structure and content of the message.
Messages must have a structure and format that is agreed upon by the
sending and receiving applications. The service flow project tools
include a flow message editor for working with message files (.sfmxsd)
and creating the interfaces used by services.
Working with operations
An operation is an artifact that specifies the information
required to invoke a flow, a nonterminal application, or an outbound Web service.
Working with ESQL expressions
Use an ESQL expression to specify a Boolean condition for
a While node or for one of the output terminals of a Switch node.
