The work context is determined by the instance from which
you enter a network of relationships between instances. This context
is defined by the design build path of the project that this instance
belongs to.
This project constitutes the starting point for the resolution
of the links between instances. If a link is not resolved in the project,
the projects hierarchy declared in the design build path is explored
in an upward direction to resolve it.
If you open or generate an instance from its definition project,
then its work context is its definition project. However, if you open
or generate a calling instance, its work context is the context of
the calling instance.
The links (super references or subreferences) resolve differently
according to the work context.
Example: A
Data Element that is called in the -CE Lines of
a Segment is redefined in a lower-level project. If the work context
is the project of the Segment, the Data Element that is resolved by
the link is the Data Element that can be accessed from the project
of the Segment. However, if the work context is a project that is
hierarchically lower than the project of the Segment (for example
if you access the Data Element through the Screen that calls it in
this project), the Data Element that is resolved by the link is the
Data Element that is redefined in the hierarchically lower project.
You select the work context when you complete the following actions:
- Open an editor. You see the instance as it is defined in the current
work context. This context is displayed in the General
Information of the Overview tab
of each editor. The project that constitutes the work context and
the projects declared higher in the hierarchy can be viewed by clicking Hierarchy.
The
same instance can be opened in two different work contexts. So it
can simultaneously be displayed in two editors. However, since it
is the same instance, any modification made in one work context is
immediately available in the other work context.
Example: Project
PROJ.A is declared higher
than project
PROJ.B in the design build path
of the location. A Data Element is defined in
PROJ.A and
is called by a Segment in
PROJ.B.
You can
open the Data Element directly from PROJ.A,
or you can access it from the Segment in PROJ.B.
In this case, two editors are simultaneously available for the Data
Element. These editors display the same information. Only the work
context differs. The search for the Data Element super references
differs if this Data Element is used by different instances in the
two projects.
- Start generating. The work context of the entry point into the
generation procedure (usually the context of the program to be generated)
is passed on to all the instances that are involved in the generation.
