What is the OutSystems server?
set of servers that compiles, deploys, manages, runs, and monitors applications
the two components of development
integration studio & service studio
two components of admin and ops
service center & lifetime
service studio
low-code visual development environment that enables developers to rapidly create amazing mobile
and web applications
integration studio
dev environment for integrating external resources;
integrate existing data and code as well as create .NET code extensions
service center
platform server management console;
admin console that is accessible via browser;
access to platform server configuration for admin and operations teams
lifetime
web app that manages lifecycle across environments;
extends service center's capabilities to cross environment scenarios;
complete application lifecycle management via browser
outsystems forge
source of downloadable components to help speed app delivery
what are screen actions bound to?
widgets on a screen
where can server actions be called?
in any flow
how many input and output parameters and local variables can server actions have?
,multiple
do screen actions have output parameters
no
do preparations have parameters or variables
no
server actions that are set as a function are...
1. restricted to one output parameter
2. available in expressions
what is an action flow
where a piece of logic is defined
actions flows can have one of what and multiple of what
one start node
multiple end nodes and raise exceptions
what can screen actions and preparations also end with (2 things) besides end and raise exception?
destination nodes and download
can a flow have multiple exception handlers?
yes, but action and exception flows cannot intersect
what does that assign statement do?
allows setting values to variables or parameters
how are values assigned in assign statements?
top to bottom and changes occur immediately
what are some accelerators that service studio provides regarding assign statements?
auto-assign of remaining attributes
standard type-matching values suggestion
what does an if statement do?
creates a conditional branch in an action flow
what does a switch statement do?
creates conditional branching with multiple branches
how does the switch statement operate?
conditions are evaluated from first to last
only the first branch that evaluates to True is executed or the otherwise branch
, and the otherwise branch is mandatory
what does a for each statement do?
allows iterating through a record list
how does a for each statement operate?
the cycle branch is followed for each record in the list
-branch must return to the for each so the loop can continue
-branch can create other conditional/alternative branches
the branch is followed after the cycle completes
what does RecordList.Current get in a for each statement
the current record being iterated within the loop
how to implement an ad-hoc loop
use the if to evaluate a loop condition
-follow a cyclic branch when condition is true
-exit the loop when condition is false
in the cyclic branch of an ad hoc loop...
branch must return to the if to continue the loop
branch can create other conditional/alternative branches
when is an exception used in a screen action?
when an operation fails unexpectedly at runtime
the execution is moved to an exception handler flow
what kind of exception handler flows can an action have?
database exception
security exceptions
custom user exceptions
how can an exception be raised?
automatically
raise exception statement
what happens when an exception is raised?
execution is moved to the handler most specific to the exception thrown
execution continues through that handler flow
how does a global exception handler get called?
if a handler doesn't exist in the current execution context, the server bubbles-up to check any outer
contexts until a matching handler is found
details about the module global exception handler
located in the common flow
