API

extype

Unit

Unit is a type that indicates no value.

Nullable

Nullable<T> is a wrapper type that can either have a value or null.

Maybe

Maybe<T> is a wrapper type that can either have a value or none. Maybe<T> looks like haxe.ds.Option<T>, but be annotatted the Default Static Extension (@:using(extype.tools.MaybeTools)).

Result

Result<T, E> is a wrapper type that can either have a value or an error. Result<T, E> looks like haxe.ds.Either<A,B>, but be annotatted the Default Static Extension (@:using(extype.tools.ResultTools)).

Lazy

Lazy<T> is a value with lazy initialization.

Tuple2 - Tuple10

Tuple[2-10] can hold any values of several different types.

Pair

Pair<T1, T2> is an alias of Tuple2<T1, T2>.

Map

Map<K, V> is a collection of key/value pairs. This is a multi-type abstract, it is instantiated as one of its specialization types depending on its type parameters.

1. if K is a String, extype.map.StringMap is used
2. if K is an Int, extype.map.IntMap is used
3. if K is an EnumValue, extype.map.EnumValueMap is used
4. if K is any other class or structure, extype.map.ObjectMap is used
5. if K is any other type, it causes a compile-time error

OrderedMap

Map<K, V> is a collection of key/value pairs. You can iterate through the keys in insertion order. This is a multi-type abstract, it is instantiated as one of its specialization types depending on its type parameters.

1. if K is a String, extype.orderedmap.OrderedStringMap is used
2. if K is an Int, extype.orderedmap.OrderedIntMap is used
3. if K is an EnumValue, extype.orderedmap.OrderedEnumValueMap is used
4. if K is any other class or structure, extype.orderedmap.OrderedObjectMap is used
5. if K is any other type, it causes a compile-time error

Set

Set<T> is a set of values. This is a multi-type abstract, it is instantiated as one of its specialization types depending on its type parameters.

1. if T is a String, extype.set.StringSet is used
2. if T is an Int, extype.set.IntSet is used
3. if T is an EnumValue, extype.set.EnumValueSet is used
4. if T is any other class or structure, extype.set.ObjectSet is used
5. if T is any other type, it causes a compile-time error

OrderedSet

OrderedSet<T> is a set of values. You can iterate through the values in insertion order. This is a multi-type abstract, it is instantiated as one of its specialization types depending on its type parameters.

1. if T is a String, extype.orderedset.OrderedStringSet is used
2. if T is an Int, extype.orderedset.OrderedIntSet is used
3. if T is an EnumValue, extype.orderedset.OrderedEnumValueSet is used
4. if T is any other class or structure, extype.orderedset.OrderedObjectSet is used
5. if T is any other type, it causes a compile-time error

LinkedList

LinkedList<T> is doubly linked list implementation.

ReadOnlyArray

ReadOnlyArray<T> is a read-only Array<T>.

ReadOnlyDynamic

ReadOnlyDynamic<T> is a read-only Dynamic<T>.

ReadOnlySet

ReadOnlySet<T> is a read-only Set<T>.

ReadOnlyMap

ReadOnlyMap<K, V> is a read-only Map<K, V>.

Exception

Exception represents the application errors. Exception is the same as haxe.Exception.

• NoDataException
• NotImplementedException

extype.extern

Mixed2 - Mixed10

Mixed[2-10] can have a value of several different types. Mixed2 is a type that likes as haxe.extern.EitherType.

ValueOrArray

ValueOrArray<T> is a type that likes as extype.extern.Mixed.Mixed2<T, Array<T>>.

ValueOrFunction

ValueOrFunction<T> is the same as extype.extern.Mixed.Mixed2<T, Void->T>.

{{ Experimental }} Extern<T>

Extern<T> is a generic-build macro type that can use @:native metadata to the anonymous structure.

extern function defineProperty(name: String, option: Extern<PropertyOption>): Void;

typedef PropertyOption = {
    @:native("default")
    var defaultValue;
}

{{ Experimental }} Indexable<TObject, TValue>

Indexable<TObject, TValue> is a type that likes as haxe.DynamicAccess<TValue>. But Indexable<TObject, TValue> is different in that can access TObject's field.

Breaking changes from v2.x

• [rename] Maybe<T> (v2) -> Nullable<T> (v3)
• [remove] Result<T> (v2)
• [add] Maybe<T> (v3)
• [add] Result<T, E> (v3)
• extype.iterator package has been deprecated. This package was not maintained long time.
• XxxError has been deprecated. Please use XxxException instead.
