All Implemented Interfaces:

Enclosing interface:

ReconnectPolicy

public static enum ReconnectPolicy.Provided
extends Enum<ReconnectPolicy.Provided>

Types of the library provided reconnection policies. This should capture most of the commonly used cases.

Enum Constant Detail

NEVER

public static final ReconnectPolicy.Provided NEVER

Only reconnect if absolutely needed, e.g. when the connection is dropped.

Apple recommends using a persistent connection. This improves the latency of sending push notification messages.

The down-side is that once the connection is closed ungracefully (e.g. because Apple server drops it), the library wouldn't detect such failure and not warn against the messages sent after the drop before the detection.

EVERY_HALF_HOUR

public static final ReconnectPolicy.Provided EVERY_HALF_HOUR

Makes a new connection if the current connection has lasted for more than half an hour.

This is the recommended mode.

This is the sweat-spot in my experiments between dropped connections while minimizing latency.

EVERY_NOTIFICATION

public static final ReconnectPolicy.Provided EVERY_NOTIFICATION

Makes a new connection for every message being sent. This option ensures that each message is actually delivered to Apple. If you send a lot of messages though, Apple may consider your requests to be a DoS attack.

Method Detail

values

public static ReconnectPolicy.Provided[] 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 (ReconnectPolicy.Provided c : ReconnectPolicy.Provided.values())
    System.out.println(c);

Returns:

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

valueOf

public static ReconnectPolicy.Provided 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
