.net - C# Variable with different amount of generic args based on some condition -

-

i'm not sure if title describing in best way i'll problem- have variable pabs list of 4-tuples, 5-tuples, or 6-tuples based on condition...the problem don't know 1 i'm having trouble declaring type variable.

basically want this:

if (condition1)     pabs = loaddata() // returns list of 4-tuples else if (condition2)     pabs = loaddata() // overloaded version returning list of 5-tuples else     pabs = loaddata() // overloaded version returning list of 6-tuples

is possible @ all?

what mean 'list of n-tuples'? should list of tuple of n elements' because .net define list list<t> , many tuples tuple<t>, tuple<t1, t2>, tuple<t1, t2, t3>, ...

if want variable pabs list<tuple<t1,..., t4>> or list<tuple<t1,..., t5>> or list<tuple<t1,..., t6>>. want pabs can take 3 different types. therefore can't give common type 3 different types unless object. later use bads must ask type , depending type is, doing something.

if(pabs list<tuple<t1,..., t4>>){...} else if(pabs list<tuple<t1,..., t5>>){...} else{...}

java - Ebean enhancement ignores a model -

-
we using avaje-agentloader enhance our ebeans. ebeans in same package. including loader, agent & base ebean library in our project (via sbt): "org.avaje" % "avaje-agentloader" % "1.1.2", "org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.5.5", "org.avaje.ebeanorm" % "avaje-ebeanorm-agent" % "4.5.2", however, when loader runs enhancement, skips 1 ebean. each ebean annotated @entity , extends com.avaje.ebean.model . there seem no differences between ones enhanced , 1 not. there no includes, or extends, etc. basically, i'm wondering if has run across issue in past, or has insights. things we've tried: specifying actual classes enhanced via serverconfig.setclasses(...) specifying pakages analyse/enhance via serverconfig.addpackage(...) or setpackages(...) not specifying @ , having loader analyse all. we've set break-point @ transformer.transform , bean in questio...

How to combine associative arrays in bash? -

-
does know of elegant way combine 2 associative arrays in bash normal array? here's i'm talking about: in bash can combine 2 normal arrays follows: declare -ar array1=( 5 10 15 ) declare -ar array2=( 20 25 30 ) declare -ar array_both=( ${array1[@]} ${array2[@]} ) item in ${array_both[@]}; echo "item: ${item}" done i want same thing 2 associative arrays, following code not work: declare -ar array1=( [5]=true [10]=true [15]=true ) declare -ar array2=( [20]=true [25]=true [30]=true ) declare -ar array_both=( ${array1[@]} ${array2[@]} ) key in ${!array_both[@]}; echo "array_both[${key}]=${array_both[${key}]}" done it gives following error: ./associative_arrays.sh: line 3: array_both: true: must use subscript when assigning associative array the following work-around came with: declare -ar array1=( [5]=true [10]=true [15]=true ) declare -ar array2=( [20]=true [25]=true [30]=true ) declare -a array_both=() key in ${!array1[@]}; ...
