intersection

Prototype: intersection(list1, list2)

Return type: slist

Description: Returns the unique elements in list1 that are also in list2.

Arguments:

  • list1 : The name of the base list variable, in the range [a-zA-Z0-9_$(){}\[\].:]+

  • list2 : The name of the intersected list variable, in the range [a-zA-Z0-9_$(){}\[\].:]+

Example:

    bundle agent test
    {
      vars:
          "a" slist => { 1,2,3,"x" };
          "b" slist => { "x" };

          "listname1" slist => { "a", "b" };
          "listname2" slist => { "a", "b" };
          "$(listname1)_str" string => join(",", $(listname1));

          "int_$(listname1)_$(listname2)" slist => intersection($(listname1), $(listname2));
          "int_$(listname1)_$(listname2)_str" string => join(",", "int_$(listname1)_$(listname2)");

      reports:
          "The intersection of list '$($(listname1)_str)' with '$($(listname2)_str)' is '$(int_$(listname1)_$(listname2)_str)'";
    }
