- java.lang.Object
- - org.wso2.carbon.mediation.initializer.persistence.AbstractStore<T>

- Type Parameters:
    `T` -
  Direct Known Subclasses:

      public abstract class AbstractStore<T>
      extends Object

  The abstract class which can be used to access a persistence storage of a specific type of mediation configuration elements. Implementations of this abstract class should ideally be parameterized to prevent it from handling more than one type of objects. This abstract class provides supports basic persistence activities of save and delete. Registry persistence activities can also be handled by this implementation if required.
