Methods

add(VT value) → Danger<PropertyRoster<VT>, PropertyExceptionA>
any(bool test(VT 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
checkComputation() → void
called on constructor.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
containsAll(Iterable<VT> models) → bool
inherited
containsPrimaryKey(PropertyName primaryKey) → Safety<bool>
inherited
containsPrimaryKeyAll(Iterable<PropertyName> primaryKeys) → Safety<bool>
primaryKeys がすべて存在する場合 true を返す.
primaryKeys が空の場合 true を返す.
values が空の場合 false を返す.
primaryKeys と values が空の場合 true を返す.
inherited
elementAt(int index) → VT
Returns the indexth element.
inherited
every(bool test(VT element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(VT element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(VT element), {VT orElse()?}) → VT
The first element that satisfies the given predicate test.
inherited
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
inherited
followedBy(Iterable<VT> other) → Iterable<VT>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(VT element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
getByIndex(int index) → Danger<VT, IterablePatternExceptionABC>
inherited
getByPrimaryKey(PropertyName primaryKey) → Danger<VT, RosterPatternExceptionB>
inherited
inactivate() → Iterable<Object>
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(VT element), {VT orElse()?}) → VT
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(VT 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(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.
inherited
singleWhere(bool test(VT element), {VT orElse()?}) → VT
The single element that satisfies test.
inherited
skip(int count) → Iterable<VT>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(VT value)) → Iterable<VT>
Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<VT>
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(VT value)) → Iterable<VT>
Creates a lazy iterable of the leading elements satisfying test.
inherited
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.
inherited
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.
inherited
toList({bool growable = true}) → List<VT>
Creates a List containing the elements of this Iterable.
inherited
toNestedStructureMap() → Map<String, Object>
条件分岐で利用するため用意した.
inherited
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.
    3. IterablePattern
    4. IterablePattern
    5. IterablePattern
    • inherited
