Enum LiveViewTableCapability

java.lang.Object

java.lang.Enum<LiveViewTableCapability>

com.streambase.liveview.client.LiveViewTableCapability

All Implemented Interfaces:

Serializable, Comparable<LiveViewTableCapability>

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

Method Detail

values

public static LiveViewTableCapability[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LiveViewTableCapability c : LiveViewTableCapability.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LiveViewTableCapability valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getReadable

public String getReadable()

toString

public String toString()

Overrides:

toString in class Enum<LiveViewTableCapability>
