public class ServiceActivityImpl

extends java.lang.Object

implements java.io.Serializable

Service Activity Implementation. The Administrator uses the SLEE’s management interface to activate and deactivate Services. Each Service has an associated Activity. The specific Java type for this Activity is ServiceActivity. The SLEE fires a Service Started Event on a ServiceActivity object after the Service is started. A Service is started after one of the following occurs:

• The SLEE is in the Running state and a ServiceManagementMBean object is invoked to activate the Service, or
• The SLEE becomes active when the SLEE transitions from the Starting to the Running state and the SLEE starts the Service because the persistent state of the Service says it should be active. SBBs register interest in Service Started Events like any other event using an event element in their deployment descriptor. An SBB can only receive a Service Started Event fired by the SLEE as an initial event since this event is fired only once on a ServiceActivity object, at the time the corresponding Service Activity begins.
• Service Started Events enable an SBB to be notified when a Service becomes active. For example, the root SBB of a Service may listen to Service Started Events by specifying the event type of the Service Started Event as an initial event type of the SBB. The root SBB of a Wake-up Service may reinstate timers from persistent data stored in Profile Tables. Daemon-like Service entities may also use the Service Started Event and Service Activity to keep them alive instead of creating and attaching to NullActivity objects.

equals

public boolean equals(java.lang.Object obj)

Description copied from class: java.lang.Object

Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

• It must be transitive. If a.equals(b) and b.equals(c), then a.equals(c) must be true as well.
• It must be symmetric. a.equals(b) and b.equals(a) must have the same value.
• It must be reflexive. a.equals(a) must always be true.
• It must be consistent. Whichever value a.equals(b) returns on the first invocation must be the value returned on all later invocations.
• a.equals(null) must be false.
• It must be consistent with hashCode(). That is, a.equals(b) must imply a.hashCode() == b.hashCode(). The reverse is not true; two objects that are not equal may have the same hashcode, but that has the potential to harm hashing performance.

This is typically overridden to throw a java.lang.ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a java.lang.NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, java.util.IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.

hashCode

public int hashCode()

Description copied from class: java.lang.Object

Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

• Semantic equality implies identical hashcodes. In other words, if a.equals(b) is true, then a.hashCode() == b.hashCode() must be as well. However, the reverse is not necessarily true, and two objects may have the same hashcode without being equal.
• It must be consistent. Whichever value o.hashCode() returns on the first invocation must be the value returned on all later invocations as long as the object exists. Notice, however, that the result of hashCode may change between separate executions of a Virtual Machine, because it is not invoked on the same object.

Notice that since hashCode is used in java.util.Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)
