Method Detail

values

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

Returns:

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

valueOf

public static RetryStrategy 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

getRetryDelay

public long getRetryDelay(int retryCount,
                          long initialDelay)

Description copied from interface: IRetryStrategy

Returns the amount of time to wait (in milliseconds) before retrying the operation.

Specified by:

getRetryDelay in interface IRetryStrategy

Parameters:

retryCount - The number of retry attempts that have already been made starting with zero (0).

initialDelay - The amount of time (in milliseconds) to wait before the first retry attempt.

Returns:

The amount of time to wait or initialDelay if this is the first retry attempt.

getRetryDelayImpl

protected abstract long getRetryDelayImpl(int retryCount,
                                          long initialDelay)
