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 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.

      • useRealmSpecificEndpointTemplate

        void useRealmSpecificEndpointTemplate​(boolean realmSpecificEndpointTemplateEnabled)
        Determines whether realm specific endpoint should be used or not.

        Set realmSpecificEndpointTemplateEnabled to “true” if the user wants to enable use of realm specific endpoint template, otherwise set it to “false”

        Parameters:
        realmSpecificEndpointTemplateEnabled - flag to enable the use of realm specific endpoint template

      • 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
