public interface FunctionsInvoke
extends AutoCloseable

API for the Functions service.

This service client uses CircuitBreakerUtils.DEFAULT_CIRCUIT_BREAKER for all the operations by default if no circuit breaker configuration is defined by the user.

Method Summary

Modifier and Type	Method and Description
String	getEndpoint() Gets the set endpoint for REST call (ex, https://www.example.com)

void	refreshClient() Rebuilds the client from scratch.
void	setEndpoint(String endpoint) Sets the endpoint to call (ex, https://www.example.com).
void	setRegion(Region region) Sets the region to call (ex, Region.US_PHOENIX_1).
void	setRegion(String regionId) Sets the region to call (ex, ‘us-phoenix-1’).

Method Detail

refreshClient

void refreshClient()

Rebuilds the client from scratch. Useful to refresh certificates.

setEndpoint

void setEndpoint(String endpoint)

Sets the endpoint to call (ex, https://www.example.com).

Parameters:

endpoint - The endpoint of the service.

getEndpoint

String getEndpoint()

Gets the set endpoint for REST call (ex, https://www.example.com)

setRegion

void setRegion(Region region)

Sets the region to call (ex, Region.US_PHOENIX_1).

Note, this will call setEndpoint after resolving the endpoint. If the service is not available in this Region, however, an IllegalArgumentException will be raised.

Parameters:

region - The region of the service.

setRegion

void setRegion(String regionId)

Sets the region to call (ex, ‘us-phoenix-1’).

Note, this will first try to map the region ID to a known Region and call setRegion.

If no known Region could be determined, it will create an endpoint based on the default endpoint format (Region.formatDefaultRegionEndpoint(Service, String) and then call setEndpoint.

Parameters:

regionId - The public region ID.

invokeFunction

InvokeFunctionResponse invokeFunction(InvokeFunctionRequest request)

Invokes a function

Note: This operation consumes a stream.

If the stream supports InputStream.mark(int) and InputStream.reset(), when a retry is necessary, the stream is reset so it starts at the beginning (or whatever the stream’s position was at the time this operation is called}.

Note this means that if the caller has used InputStream.mark(int) before, then the mark will not be the same anymore after this operation, and a subsequent call to InputStream.reset() by the caller will reset the stream not to the caller’s mark, but to the position the stream was in when this operation was called.

If the stream is a FileInputStream, and the stream’s FileChannel position can be changed (like for a regular file), the stream will be wrapped in such a way that it does provide support for InputStream.mark(int) and InputStream.reset(). Then the same procedure as above is followed. If the stream’s FileChannel position cannot be changed (like for a named pipe), then the stream’s contents will be buffered in memory, as described below.

If the stream does not support InputStream.mark(int) and InputStream.reset(), then the stream is wrapped in a BufferedInputStream, which means the entire contents may be buffered in memory. Then the same procedure as above is followed.

The contents of the stream, except when the stream is a FileInputStream whose FileChannel position can be changed, should be less than 2 GiB in size if retries are used. This is because streams 2 GiB in size or larger do no guarantee that mark-and-reset can be performed. If the stream is larger, do not use built-in retries and manage retries yourself.

Parameters:

request - The request object containing the details to send

Returns:

A response object containing details about the completed operation

Throws:

BmcException - when an error occurs. This operation will not retry by default, users can also use RetryConfiguration.SDK_DEFAULT_RETRY_CONFIGURATION provided by the SDK to enable retries for it. The specifics of the default retry strategy are described here https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/javasdkconcepts.htm#javasdkconcepts_topic_Retries
