Method Detail

values

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

Returns:

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

valueOf

public static NoRestartBackoffTimeStrategy 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

canRestart

public boolean canRestart()

Description copied from interface: RestartBackoffTimeStrategy

Returns whether a restart should be conducted.

Specified by:

canRestart in interface RestartBackoffTimeStrategy

Returns:

whether a restart should be conducted

getBackoffTime

public long getBackoffTime()

Description copied from interface: RestartBackoffTimeStrategy

Returns the delay to do the restarting.

Specified by:

getBackoffTime in interface RestartBackoffTimeStrategy

Returns:

the delay to do the restarting

notifyFailure

public boolean notifyFailure(Throwable cause)

Description copied from interface: RestartBackoffTimeStrategy

Notify the strategy about the task failure cause.

Specified by:

notifyFailure in interface RestartBackoffTimeStrategy

Parameters:

cause - of the task failure

Returns:

True means that the current failure is the first one after the most-recent failure handling happened, false means that there has been a failure before that was not handled, yet, and the current failure will be considered in a combined failure handling effort.
