鉴于应用程序范围内的对象集合以及许多需要频繁访问这些对象的无关类,提供所述访问的最佳方法是什么？

例:

// Object A, stored in collections, used to do useful things
class A
{
  ...
public:
  QString property(const QString& propertyName) {return m_properties.value(propertyName);}

protected:
  QHash<QString,QString> m_properties;
}

// Collection class, contains methods to:
// - Access members of collections
// - Add/Remove members from collection
class GlobalCollection
{
public:
  // Accessors to collection/collection members
  static A* getAs() {return aHash;}
  static QHash<QString,A*> getAByKey(const QString& key) {return aHash.value(key);}
  static QList<A*> getAsMatchingCriteria(const QString& property, const QString& value)
  {
    QHash<A*> subsetOfA;

    foreach(A* pA, …

jQuery(document).ready(function() {
    jQuery(".multipleDataRow").on("click", "[id^='multiremove_']", function() { 
        //code here to delete
    });
});

我想避免在按键"按"时调用删除功能

当我专注于其他文本框并按下输入按钮时,点击功能会触发.

删除按钮位于具有"multipleDataRow"类的容器内.

删除功能在其他字段上按键输入时继续触发.
