# ExitCodeGenerators class

A container and manager for multiple ExitCodeGenerator instances.

This class allows you to dynamically register and prioritize exit code generators. These generators are responsible for computing application exit codes based on exceptions thrown during execution.

It supports:

- Adding generators directly
- Mapping exceptions to exit codes using ExitCodeExceptionHandler
- Aggregating generators from multiple sources
- Resolving a final exit code from all registered generators

Example:

    final generators = ExitCodeGenerators();

    generators.add(Exception("App crashed"), MyExitCodeMapper());
    int code = generators.getExitCode();
    exit(code);

## Methods

add(Throwable exception, ExitCodeExceptionHandler mapper) → void
  Adds a single ExitCodeExceptionHandler for a given `exception`.
addAll(Throwable exception, List<ExitCodeExceptionHandler> mappers) → void
  Adds a list of ExitCodeExceptionHandlers for a given `exception`, mapping each one to an internal `_MappedExitCodeGenerator`.
addAllGenerators(List<ExitCodeGenerator> generators) → void
  Adds a list of ExitCodeGenerator instances directly.
addAllMappers<T extends ExitCodeExceptionHandler>(Throwable exception, Iterable<T> mappers) → void
  Adds a collection of ExitCodeExceptionHandlers for a given `exception`.
addAllMultiGenerators<T extends ExitCodeGenerator>(Iterable<T> generators) → void
  Adds multiple ExitCodeGenerators to this manager.
addGenerator(ExitCodeGenerator generator) → void
  Adds a single ExitCodeGenerator and ensures all generators are ordered using AnnotationAwareOrderComparator.
any(bool test(ExitCodeGenerator element)) → bool
  Checks whether any element of this iterable satisfies `test`.
  inherited
cast<R>() → Iterable<R>
  A view of this iterable as an iterable of `R` instances.
  inherited
contains(Object? element) → bool
  Whether the collection contains an element equal to `element`.
  inherited
elementAt(int index) → ExitCodeGenerator
  Returns the `index`th element.
  inherited
every(bool test(ExitCodeGenerator element)) → bool
  Checks whether every element of this iterable satisfies `test`.
  inherited
expand<T>(Iterable<T> toElements(ExitCodeGenerator element)) → Iterable<T>
  Expands each element of this Iterable into zero or more elements.
  inherited
firstWhere(bool test(ExitCodeGenerator element), {ExitCodeGenerator orElse()?}) → ExitCodeGenerator
  The first element that satisfies the given predicate `test`.
  inherited
fold<T>(T initialValue, T combine(T previousValue, ExitCodeGenerator element)) → T
  Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
  inherited
followedBy(Iterable<ExitCodeGenerator> other) → Iterable<ExitCodeGenerator>
  Creates the lazy concatenation of this iterable and `other`.
  inherited
forEach(void action(ExitCodeGenerator element)) → void
  Invokes `action` on each element of this iterable in iteration order.
  inherited
getExitCode() → int
  Resolves the final exit code by iterating over all registered ExitCodeGenerators and returning the first non-zero code.
join([String separator = ""]) → String
  Converts each element to a String and concatenates the strings.
  inherited
lastWhere(bool test(ExitCodeGenerator element), {ExitCodeGenerator orElse()?}) → ExitCodeGenerator
  The last element that satisfies the given predicate `test`.
  inherited
map<T>(T toElement(ExitCodeGenerator e)) → Iterable<T>
  The current elements of this iterable modified by `toElement`.
  inherited
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a nonexistent method or property is accessed.
  inherited
reduce(ExitCodeGenerator combine(ExitCodeGenerator value, ExitCodeGenerator element)) → ExitCodeGenerator
  Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
  inherited
singleWhere(bool test(ExitCodeGenerator element), {ExitCodeGenerator orElse()?}) → ExitCodeGenerator
  The single element that satisfies `test`.
  inherited
skip(int count) → Iterable<ExitCodeGenerator>
  Creates an Iterable that provides all but the first `count` elements.
  inherited
skipWhile(bool test(ExitCodeGenerator value)) → Iterable<ExitCodeGenerator>
  Creates an `Iterable` that skips leading elements while `test` is satisfied.
  inherited
take(int count) → Iterable<ExitCodeGenerator>
  Creates a lazy iterable of the `count` first elements of this iterable.
  inherited
takeWhile(bool test(ExitCodeGenerator value)) → Iterable<ExitCodeGenerator>
  Creates a lazy iterable of the leading elements satisfying `test`.
  inherited
toList({bool growable = true}) → List<ExitCodeGenerator>
  Creates a List containing the elements of this Iterable.
  inherited
toSet() → Set<ExitCodeGenerator>
  Creates a Set containing the same elements as this iterable.
  inherited
toString() → String
  Returns a string representation of (some of) the elements of `this`.
  inherited
where(bool test(ExitCodeGenerator element)) → Iterable<ExitCodeGenerator>
  Creates a new lazy Iterable with all elements that satisfy the predicate `test`.
  inherited
whereType<T>() → Iterable<T>
