SessionAttributeMetadata (Payara Project 6.2022.1.Alpha3 API)

java.lang.Object
- org.glassfish.web.ha.session.management.SessionAttributeMetadata

All Implemented Interfaces:

Serializable
```
public final class SessionAttributeMetadata
extends Object
implements Serializable
```
AttributeMetadata contains the metadata of an attribute that is part of an Http Session. When a container decides to save a session it passes an instance of CompositeMetaData which contains a collection of AttributeMetadata.
The attribute in question could have been deleted, or modified or could be a new attribute inside the HttpSession. getOperation() tells exactly what operation needs to be performed for this attribute
The attribute state/data itself can be obtained with getState(). Since an attribute is part of a session, the attributes must be deleted when the session is removed. The CompositeMetadata contains the last access time and inactive timeout for the session.
