Constructors

CloudStorageRetryHandler(CloudStorageConfiguration config)

public CloudStorageRetryHandler(CloudStorageConfiguration config)

Create a CloudStorageRetryHandler with the maximum retries and reopens set to the same value.

Parameter

Name	Description
`config`	`CloudStorageConfiguration` configuration for reopens and retryable codes.

CloudStorageRetryHandler(int maxRetriesAndReopens) (deprecated)

public CloudStorageRetryHandler(int maxRetriesAndReopens)

Deprecated. use CloudStorageRetryHandler(CloudStorageConfiguration) instead.

Create a CloudStorageRetryHandler with the maximum retries and reopens set to the same value.

Parameter

Name	Description
`maxRetriesAndReopens`	`int` value for both maxRetries and maxReopens

CloudStorageRetryHandler(int maxRetries, int maxReopens) (deprecated)

public CloudStorageRetryHandler(int maxRetries, int maxReopens)

Deprecated. use CloudStorageRetryHandler(CloudStorageConfiguration) instead.

Create a CloudStorageRetryHandler with the maximum retries and reopens set to different values.

Parameters

Name	Description
`maxRetries`	`int` maximum number of retries
`maxReopens`	`int` maximum number of reopens

CloudStorageRetryHandler(int maxRetries, int maxReopens, CloudStorageConfiguration config)

public CloudStorageRetryHandler(int maxRetries, int maxReopens, CloudStorageConfiguration config)

Create a CloudStorageRetryHandler with the maximum retries and reopens set to different values.

Parameters

Name	Description
`maxRetries`	`int` maximum number of retries
`maxReopens`	`int` maximum number of reopens (overrides what's in the config)
`config`	`CloudStorageConfiguration` http codes we'll retry on, and exceptions we'll reopen on.

Methods

handleStorageException(StorageException exs)

public boolean handleStorageException(StorageException exs)

Checks whether we should retry, reopen, or give up.

In the latter case it throws an exception (this includes the scenario where we exhausted the retry count).

Otherwise, it sleeps for a bit and returns whether we should reopen. The sleep time is dependent on the retry number.

Parameter

Name	Description
`exs`	`com.google.cloud.storage.StorageException` caught StorageException

Returns

Type	Description
`boolean`	True if you need to reopen and then try again. False if you can just try again.

Exceptions

Type	Description
`com.google.cloud.storage.StorageException`	if the exception is not retryable, or if you ran out of retries.

reopens()

public int reopens()

Returns

Type	Description
`int`	number of reopens we've performed

retries()

public int retries()

Returns

Type	Description
`int`	number of retries we've performed
