Public methods

configureRetryStrategy

public static HttpRequestInitializer configureRetryStrategy (HttpRequestInitializer initializer)

Setup a retry strategy for the provided HttpRequestInitializer. In case of server errors requests will be automatically retried with an exponential backoff.

Parameters
`initializer`	`HttpRequestInitializer`: - an initializer which will setup a retry strategy.

Returns
`HttpRequestInitializer`	an initializer that will retry failed requests automatically.

configureRetryStrategyAndTimeout

public static HttpRequestInitializer configureRetryStrategyAndTimeout (HttpRequestInitializer initializer, 
                int connectTimeout, 
                int readTimeout)

Setup a retry strategy for the provided HttpRequestInitializer. In case of server errors requests will be automatically retried with an exponential backoff.

Parameters
`initializer`	`HttpRequestInitializer`: - an initializer which will setup a retry strategy.
`connectTimeout`	`int`
`readTimeout`	`int`

Returns
`HttpRequestInitializer`	an initializer that will retry failed requests automatically.

createCredential

public static Credentials createCredential ( scopes, 
                File primaryKeyFile, 
                String hostOptionKeyFileName, 
                File... backupKeyFiles)

Try to create credential with different key files or from local host.

1. If primaryKeyFile is set, try to use it to create credential. 2. Try to get corresponding key files from HostOptions. 3. Try to use backup key files. 4. Use local default credential.

Parameters
`scopes`	: scopes for the credential.
`primaryKeyFile`	`File`: the primary json key file; it can be null.
`hostOptionKeyFileName`	`String`: `HostOptions`'service-account-json-key-file option's key; it can be null.
`backupKeyFiles`	`File`: backup key files.

Returns
`Credentials`	a `Credential`

Throws
	IOException
	GeneralSecurityException

createCredential

public static Credentials createCredential ( scopes, 
                boolean useCredentialFactory, 
                File primaryKeyFile, 
                String hostOptionKeyFileName, 
                File... backupKeyFiles)

Try to create credential with different key files or from local host.

1. Use ICredentialFactory if useCredentialFactory is true and a ICredentialFactory is configured. If primaryKeyFile is set, try to use it to create credential. 2. Try to get corresponding key files from HostOptions. 3. Try to use backup key files. 4. Use local default credential.

Parameters
`scopes`	: scopes for the credential.
`useCredentialFactory`	`boolean`: use credential factory if it's configured.
`primaryKeyFile`	`File`: the primary json key file; it can be null.
`hostOptionKeyFileName`	`String`: `HostOptions`'service-account-json-key-file option's key; it can be null.
`backupKeyFiles`	`File`: backup key files.

Returns
`Credentials`	a `Credential`

Throws
	IOException
	GeneralSecurityException

createCredentialFromJsonKeyFile

public static Credentials createCredentialFromJsonKeyFile (File file, 
                 scopes)

Create credential from json key file.

Parameters
`file`	`File`: is the p12 key file
`scopes`	: is the API's scope.

Returns
`Credentials`	a `Credential`.

Throws
	FileNotFoundException
	IOException
	GeneralSecurityException

setHttpTimeout

public static HttpRequestInitializer setHttpTimeout (HttpRequestInitializer requestInitializer, 
                int connectTimeout, 
                int readTimeout)

Parameters
`requestInitializer`	`HttpRequestInitializer`: a `HttpRequestInitializer`, normally it's `Credential`.
`connectTimeout`	`int`: connect timeout in milliseconds.
`readTimeout`	`int`: read timeout in milliseconds.

Returns
`HttpRequestInitializer`	a `HttpRequestInitializer` with timeout.
