Enum Class ReferencePolicy

All Implemented Interfaces:
Serializable, Comparable<ReferencePolicy>, Constable

public enum ReferencePolicy extends Enum<ReferencePolicy>
Policy for the Reference annotation.
  • Enum Constant Details

    • STATIC

      public static final ReferencePolicy STATIC
      The static policy is the most simple policy and is the default policy. A component instance never sees any of the dynamics. Component configurations are deactivated before any bound service for a reference having a static policy becomes unavailable. If a target service is available to replace the bound service which became unavailable, the component configuration must be reactivated and bound to the replacement service.

      public static final ReferencePolicy DYNAMIC
      The dynamic policy is slightly more complex since the component implementation must properly handle changes in the set of bound services. With the dynamic policy, SCR can change the set of bound services without deactivating a component configuration. If the component uses method injection to access services, then the component instance will be notified of changes in the set of bound services by calls to the bind and unbind methods.
  • Method Details

    • values

      public static ReferencePolicy[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static ReferencePolicy valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
    • toString

      public String toString()
      toString in class Enum<ReferencePolicy>
