Enum Class LiveViewTableCapability

java.lang.Object

java.lang.Enum<LiveViewTableCapability>

com.streambase.liveview.client.LiveViewTableCapability

All Implemented Interfaces:

Serializable, Comparable<LiveViewTableCapability>, Constable

public enum LiveViewTableCapability
extends Enum<LiveViewTableCapability>

Enumerates certain capabilities that may be supported by a table.

Since this feature is known to servers only since 1.4, older servers will have capabilities reported to directly by this client layer. In particular, TopN and Time Window queries did not exist, and are thus never reported for any table for servers older than 1.4.

Since:

1.4
