Lvg Output Filter Options
After the results are generated from the mutation, several filter options can be applied by using output filter options. Such options include being notified the end of the set of variants returned, modifying cases, combining records, filtering out records with/without certain categories or inflections, specifying output fields, being notified when a transformation produces no output, restricting the number of variants returned, show categories/inflections in name, sorting features of outputs, and displaying the filtered input term.
The following table lists all output filter options for LVG programs
| Original Flag | New Flag | Feature Descriptions |
| ccgi | ccgi | Mark the end of the set of variants returned |
| C: [case_sensitive] [case_insensitive] [preserve_case] [dont] | C:INT | Case modifying function |
| CR:[o][oc][oe][oi] | Combine record by output term, term and category, term and EUI, term and inflection | |
| DC:LONG | Display variants contain category specified | |
| DI:LONG | Display variants contain inflection specified | |
| EC:LONG | Display variants exclude category specified | |
| EI:LONG | Display variants exclude inflection specified | |
| FFIELDLIST | F:INT F:INT:INT:.. | Copy specified field(s) from input to output |
| n | n | Return a "-No Output-" message |
| RN | R:INT | Restrict the number of variants returned |
| SC | Show category names | |
| SI | Show inflection names | |
| St:[o][oc][oci] | Sort outputs by terms in an alphabetical order, category value, and inflection value | |
| ti | Display only the filtered input term in the output |
All above filters are operated on the generated results from lvg operations. In other words, these filters work on a vector of LexItems.
