Methods

any(bool test(VT element)) bool
Checks whether any element of this iterable satisfies test.
override
asNameMap() Map<String, T>

Available on Iterable<T>, provided by the EnumByName extension

Creates a map from the names of enum values to the values.
byName(String name) → T

Available on Iterable<T>, provided by the EnumByName extension

Finds the enum value in this list with name name.
cast<R>() Iterable<R>
A view of this iterable as an iterable of R instances.
override
checkComputation() → void
called on constructor.
override
contains(Object? element) bool
Whether the collection contains an element equal to element.
override
containsAll(Iterable<VT> models) bool
override
elementAt(int index) → VT
Returns the indexth element.
override
every(bool test(VT element)) bool
Checks whether every element of this iterable satisfies test.
override
expand<T>(Iterable<T> toElements(VT element)) Iterable<T>
Expands each element of this Iterable into zero or more elements.
override
firstWhere(bool test(VT element), {VT orElse()?}) → VT
The first element that satisfies the given predicate test.
override
fold<T>(T initialValue, T combine(T previousValue, VT element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
override
followedBy(Iterable<VT> other) Iterable<VT>
Creates the lazy concatenation of this iterable and other.
override
forEach(void action(VT element)) → void
Invokes action on each element of this iterable in iteration order.
override
getByIndex(int index) Danger<VT, IterablePatternExceptionABC>
override
inactivate() Iterable<Object>
override
join([String separator = ""]) String
Converts each element to a String and concatenates the strings.
override
lastWhere(bool test(VT element), {VT orElse()?}) → VT
The last element that satisfies the given predicate test.
override
map<T>(T toElement(VT e)) Iterable<T>
The current elements of this iterable modified by toElement.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(VT combine(VT value, VT element)) → VT
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
override
singleWhere(bool test(VT element), {VT orElse()?}) → VT
The single element that satisfies test.
override
skip(int count) Iterable<VT>
Creates an Iterable that provides all but the first count elements.
override
skipWhile(bool test(VT value)) Iterable<VT>
Creates an Iterable that skips leading elements while test is satisfied.
override
take(int count) Iterable<VT>
Creates a lazy iterable of the count first elements of this iterable.
override
takeWhile(bool test(VT value)) Iterable<VT>
Creates a lazy iterable of the leading elements satisfying test.
override
toInactivatedJson() Map<String, dynamic>
test 時に 等価比較が行えるように 一部の property 値を無効化する(一定の値に変更する)処理を加えた json を出力する.
例えば process id など, system によって割り振られる値をこちらで指定できないので このような場合に利用する.
override
toJson() Map<String, dynamic>
ここでの toJson とは json へ encode 可能な形式へ変換するという意味で使われる.
つまり json string を返すというわけではない.
また serialize としても利用するため deserialize 可能でなければならない.
override
toList({bool growable = true}) List<VT>
Creates a List containing the elements of this Iterable.
override
toNestedStructureMap() Map<String, Object>
条件分岐で利用するため用意した.
override
toNestedStructureMapEntry() MapEntry<String, Object>
  • Map ではなく MapEntry である必要性 まず 前提として key 名には 型 を使う. しかし それだと同じ key 名になってしまうことがあり そうなると 上書きされてしまい これを防ぐ必要がある. root の key 名は 型 のみだが nest された key 名は 型 + 接頭辞 or 接尾辞 とする. nest された型の key 名を編集するにあたり MapEntry がやりやすい.

  • それぞれの値の返し方

    1. AggregationPattern で toShorthand を実装 toShorthand の処理は定義側が自由に定義する. だいたいは csv のようなコンマ区切りの値をまとめた1行表示を想定している. 多重入れ子構造の class の場合一番深い class にこの toShorthand が定義されていることを期待している. 一番深い class は すべての property が ValuePattern であるはずなので.
    2. AggregationPattern で toShorthand を未実装 これは 階層の上の部分を想定しており これらは自分が property としてもつ AggregationPattern.toNestedStructureMapEntry.value, ValuePattern.value などを呼ぶことを想定.
