A Java Exception sorter -- to categorize Java Exceptions into Enum with a Map-based DSL (such as YAML or JSON).
(Note that "sort" does not mean reordering here, but categorizing. It is inspired from coin sorters.)
enum Target {
ONE,
TWO,
THREE,
DEFAULT,
;
}
final List<Map<String, Object>> dslMaps = load(/* Map-based representation of DSL converted from something, such as YAML */);
final SortEx<Target> sortex = SortEx.from(dslMaps, Target.class);
final Target sorted = sortex.matches(exceptionToSort, Target.DEFAULT);
switch (sorted) {
case ONE:
...
break;
case TWO:
...
break;
case THREE:
...
break;
default:
...
break;
}
The Map-based DSL for sorting would look like below, for example. This example representation is with YAML.
- class_equals: java.io.UncheckedIOException # Exact match.
message_matches_either_of:
- "Unexpected" # Exact match.
cause_matches_either_of:
- class_extends: java.io.IOException # The cause is a subclass of IOException.
message_matches_either_of:
- "/File .+ not found./" # Regular expression.
direct: true // Direct cause.
sorted_into: "EXPECTED_1" // It expects the enum contains a constant "EXPECTED_1".
