取得符合指定定義所定義限制的所有匯出。

Protected MustOverride Function GetExportsCore (definition As ImportDefinition, atomicComposition As AtomicComposition) As IEnumerable(Of Export)

參數

definition
ImportDefinition

一個物件，該物件定義要傳回的 Export 物件的條件。

atomicComposition
AtomicComposition

用於撰寫的異動容器。

傳回

IEnumerable<Export>

集合，包含符合指定之條件的所有匯出。

備註

此方法的覆寫不應將基數相關不符視為錯誤，而且不應該在這些情況下擲回例外狀況。 例如，如果 是 CardinalityExactlyOne 且有零 Export 個物件符合指定 ImportDefinition之的條件，則應該傳回空 IEnumerable<T> 集合。
