Thank you for your answer.<br>
Yes it's what i have done as i didn't find a better idea. User will
have to enter it but if the DSL is clear shouldn't be a problem.<br>
<br>
In fact 1 rule will be something like :<br>
- Find a map with properties 'prop1' = "value1" and store it in
variable $m1 (because i will need access in the Then part also)<br>
- Find a map with properties 'prop1' = "value1" (and different then
$m1) and store it in variable $m2.<br>
- And using properties 'unixTimestampInSecond' and
'unixTimestampInMillisecond' (so complete timestamp in Millisecond =
'unixTimestampInSecond' * 1000 + 'unixTimestampInMillisecond') of
the 2 Maps, $m1 has to be before $m2.<br>
<br>
So i use 2 times this one to find $m1 and $m2 : <tt>[when]The
property {key:ENUM:Map.properties} of the map <b>{mapVar}</b> is
{value}=<b>{mapVar} </b>: Map((this["{key}"] == "{value}"))</tt><br>
<br>
Then this one to drop the case when the Map would be the same : <tt>[when]The
map <b>{mapVar1}</b> is not map </tt><tt><b>{mapVar2}</b></tt><tt>
=<b> eval ({mapVar1}</b>["id"] != </tt><tt><b>{mapVar2}</b>["id"]</tt><tt>))</tt><b><br>
</b><br>
Then i can do something like : <tt>[when]The map <b>{mapVar1}</b>
is before </tt><tt><b>{mapVar2}</b></tt><tt> =<b> eval
(orderTimeStamp(</b></tt>(Long) <tt><b>{mapVar1}</b>["</tt>unixTimestampInSecond<tt>"],
</tt>(Long) <tt><b>{mapVar1}</b>["</tt>unixTimestampInMillisecond<tt>"],
</tt>(Long) <tt><b>{mapVar2}</b>["</tt> unixTimestampInSecond<tt>"],
</tt>(Long) <tt> </tt><tt><b>{mapVar2}</b>["</tt>unixTimestampInMillisecond<tt>"]</tt><tt>))</tt><b><br>
</b><br>
where i would have a function <tt><b>: <br>
function Boolean orderTimeStamp(Long a, Long b, Long c, Long d)</b></tt>
<br>
{<br>
Long timestamp1 = a*1000+b;<br>
Long timestamp2 = c*1000+d;<br>
<br>
if (timestamp1 <= timestamp2)<br>
return true;<br>
else<br>
return false;<br>
}<br>
<br>
I will rethink of POJO but i think, it will be more ennoying to
update any change. I will need a reference to these maps in almost
every case in the THEN clause so not a big problem finally.<br>
<br>
<br>
For the second question :<br>
<br>
In fact i have to make rules using these Enum and DSL and put rules
in their specific files.<br>
For example now i am working with 4 different drl files :<br>
<br>
- file1.drl which contains rule1, rule2, rule3, rule4<br>
- file2.drl which contains rule5, rule6, rule7, rule8<br>
- file3.drl which contains rule9, rule10, rule11, rule12<br>
- file4.drl which contains rule13, rule14, rule15, rule16<br>
<br>
These files have to have this specific name and the name cannot
change because the java code use this name to load the drl file in
the session.<br>
<br>
To put each rule in its specific file, do i have to create a package
per file and name the package with the name of the file i want? And
copy Enum and DSL in each package or can i put this in global? Or
maybe be is there a better way i didn't find?<br>
<br>
<br>
To use the Test Scenario, do you know if we have to do special
things? I tried to add Maps in the Given part and run the scenario
but i get an error ; "unable to find constructor for java.util.Map"
and the same if i put a boolean, string... Is the Guvnor Test
Scenario not able to find java class and how to make it reachable? <br>
I have already tried Test Scenario with adding object for which i
gave a Pojo but never with basic java type.<br>
<br>
Thanks again<br>

For your problem of different instances of a map : If you want to
match 2 maps, and compare them, your have to set a placeholder in
your DSL to set the variable's name<br>
<tt>[when]The property {key:ENUM:Map.properties} of the map <b>{mapVar}</b>
is {value}=<b>{mapVar} </b>: Map((this["{key}"] == "{value}"))</tt><br>
<br>
<b> </b>And another DSL phrase to check that instances are
different<br>
<tt>[when]The map <b>{mapVar1}</b> is not map </tt><tt><b>{mapVar2}</b></tt><tt>
=<b> eval ({mapVar1}</b>["id"] != </tt><tt><b>{mapVar2}</b>["id"]</tt><tt>))</tt><b><br>
</b><br>
But it will force your users to handle variables. I can't see
simpler way for doing that with DSL.<br>
<br>
You may consider completely another way. If your property lists
are constant (and they are because you can create static enums),
you can write a simple program to generate the corresponding POJOs
(which contains the map inside them and use it in set/get methods
for corresponding key) and create a jar with them. <br>
Each POJO will then have its fields listed automatically in Guided
Editor, which will prevent you for writing complex DSL and enums,
and provide a good way for users to edit rules. For instance, you
can bind an object to a variable only if you need it (with DSL you
are forced to bind a variable at each time you use the phrase),
and you can use other operator (not only equals) without writing a
new DSL phrase.<br>
<br>
<br>
I did not understand this question :<br>
<br>
<blockquote

type="cite">I have to put my rules in 4 drl files separate (i
know which rules go in which drl file), is the only way to
create a different package for each drl file i want? And to put
the Enum and DSL part in Global if i have to use it for the 4
files? If i want a precise name for my drl file, i have to give
this exact name to the package?<br>
</blockquote>
But yes, a DSL (and enums) is specific to its package.<br>
