This is mainly to be compatibe with other classes API.
In a lot of classes, we define methods like this:
```Eiffel
method (req: WSF_REQUEST; res: WSF_RESPONSE)
do
...
end
```
With the context, the signature becomes:
```Eiffel
method (ctx: C; req: WSF_REQUEST; res: WSF_RESPONSE)
do
...
end
```
So, I can't build a filter chain where one filter is with context
and one is without context (I can't call
WSF_FILTER.set_next (a_next: WSF_FILTER) with a filter that is a
descendant of WSF_CONTEXT_HANDLER).
Moreover, having to play with generic types just to pass some
data from one filter to another is a bit overkill imho.
Because this is really what I use contexts for:
to pass data from one filter to the next one.
Regarding execution_variable and strong typing, if we want to achieve these,
I realize we could write a class with one getter and one setter like this:
```Eiffel
class
TYPED_DATA
feature -- Access
user (req: WSF_REQUEST): detachable USER
do
if attached {USER} req.execution_variable ("user") as l_user then
Result := l_user
end
end
feature -- Element change
set_user (req: WSF_REQUEST; a_user: USER)
do
req.set_execution_variable ("user", a_user)
end
```
Now, I realize this is a major change since the last time we talked about this,
but at the end, after having played with both, I prefer the one with
execution_variable.
Eiffel Web Framework
Overview
Official project site for Eiffel Web Framework:
For more information please have a look at the related wiki:
For download, check
Requirements
- Compiling from EiffelStudio 7.0
- Developped using EiffelStudio 7.1 (on Windows, Linux)
- Tested using EiffelStudio 7.1 with "jenkins" CI server (not anymore compatible with 6.8 due to use of `TABLE_ITERABLE')
- The code have to allow void-safe compilation and non void-safe system (see more about void-safety )
How to get the source code?
Using git version >= 1.6.5
- git clone --recursive https://github.com/EiffelWebFramework/EWF.git
Otherwise, try
- git clone https://github.com/EiffelWebFramework/EWF.git
- cd Eiffel-Web-Framework
- git submodule update --init
- git submodule foreach --recursive git checkout master
An alternative to the last 2 instructions is to use the script from tools folder:
-
cd tools
-
update_git_working_copy
-
And to build the required and related Clibs
- cd contrib/ise_library/cURL
- geant compile
