Interface ActivityHandle

public interface ActivityHandle

The ActivityHandle interface is implemented by each Resource Adaptor. An activity handle uniquely identifies an activity. There is a one-to-one relationship between an activity handle and its associated activity. Within the SLEE events are always delivered on an ActivityContext. The ActivityHandle is used by the SLEE to identify which ActivityContext to use.

An implementation of this interface must implement the equals and hashCode methods in this interface so that:

• handle1.equals(handle2) is true if and only if the two handles reference the same underlying activity object
• handle.hashCode() always returns the same value for the same underlying activity object, regardless of the Java VM process in which the activity may reside.

Since:

SLEE 1.1

Modifier and Type	Method and Description
boolean	equals(Object obj) Compare this activity handle for equality with another.
int	hashCode() Get a hash code for this activity handle.

Method Detail

equals

boolean equals(Object obj)

Compare this activity handle for equality with another. Two activity handles are considered equal if they both reference the same underlying activity object.

Overrides:

equals in class Object

Parameters:

obj - the object to compare this with.

Returns:

true if obj is an instance of this class and references the same underlying activity as this, false otherwise.

hashCode

int hashCode()

Get a hash code for this activity handle. The hash code must be consistent across multiple Java VM processes and marshal/unmarshal operations.

Overrides:

hashCode in class Object

Returns:

a hash code value.
