You'll need 2 rules, one for truncating a key that does not match and
another one for handling the match. If you have to handle absolute failure
(not even a matches) you'll need a third rule and a more complex fact for
storing the original and the truncated string.
These 2 rules are untested:
rule truncate when not found
when
$s: String( length 0 )
$m: Map( keySet not contains $s )
then
retract( $s );
insert( $s.substring( 0, $s.length() -1 );
end
rule found
when
$s: String()
$m: Map( keySet contains $s )
then
System.out.println( key + $s + is in the Map );
end

Hi
I want to match a string with the contents of hashmap. The process is like
this.
Let the string is abcd
First it will search for abcd in the map
if found i have to assign it to a variable else i has to remove the last
alphabet (abc) and have to match with hashmap like is the process.
My Problem is iam not able to do that iteration in when part
What i have done is i will check the condition in when part if it matches
the hashmap then it will exit. Else it will satisfies the condition(String
not matching any of hashmap contents) and goes in then and update the
string
by removing the last alphabet and loops .
rule somerule
no-loop false
when
condition for checking that hashmap has no key of String s and
s.length0
then
modify the String s by removing last alphabet
end
is there any option to do the looping in the when part itself
