Enum Constant Detail

BEST_EFFORT

public static final Reliability.Kind BEST_EFFORT

Indicates that it is acceptable to not retry propagation of any samples. Presumably new values for the samples are generated often enough that it is not necessary to re-send or acknowledge any samples. This is the default value for DataReaders and Topics.

RELIABLE

public static final Reliability.Kind RELIABLE

Specifies the Service will attempt to deliver all samples in its history. Missed samples may be retried. In steady-state (no modifications communicated via the DataWriter) the middleware guarantees that all samples in the DataWriter history will eventually be delivered to all the DataReader objects. Outside steady state the History and ResourceLimits will determine how samples become part of the history and whether samples can be discarded from it. This is the default value for DataWriters.

Method Detail

values

public static Reliability.Kind[] 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 (Reliability.Kind c : Reliability.Kind.values())
    System.out.println(c);

Returns:

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

valueOf

public static Reliability.Kind 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
