Class AbstractRetryPolicy

java.lang.Object

com.alarmpoint.integrationagent.exceptions.retriable.AbstractRetryPolicy

All Implemented Interfaces:

DelayPolicy, RetryPolicy

Direct Known Subclasses:

MaxAttemptRetryPolicy, MaxTimeRetryPolicy

public abstract class AbstractRetryPolicy
extends java.lang.Object
implements RetryPolicy

A base class that provides pluggable delays so that subclasses need only implement RetryPolicy.isRetriable(int, long).

Constructor Detail

AbstractRetryPolicy

protected AbstractRetryPolicy(DelayPolicy delayPolicy)

Default constructor.

Parameters:

delayPolicy - - the policy that computes delays between retry attempts; must be non-null

Method Detail

getDelay

public long getDelay(int numAttempts,
                     long lastDelay)

Gets the minimum amount of time that must elapse before the next retry attempt.

Specified by:

getDelay in interface DelayPolicy

Parameters:

numAttempts - - the number of previous attempts (including first attempt and retries); assumed to be >= 1

lastDelay - - the delay (in milliseconds) returned by the previous call to this method (i.e., with numAttempts-1); -1 if not previously code (i.e., when numAttempts==0

Returns:

a non-negative integer indicating the delay in milliseconds

toString

public java.lang.String toString()

Description copied from interface: DelayPolicy

Returns a human-readable description of this policy.

Specified by:

toString in interface DelayPolicy

Overrides:

toString in class java.lang.Object
