Module Overview
This module provides functions to interact with the Ballerina runtime and the runtime invocation context.
Invocation Context
The Invocation Context is a data holder, which is created per request and preserved for a single request-response flow. It comprises of a unique ID and an attribute map to hold the context information.
The following code snippet shows how to access the runtime:InvocationContext
and how to set the data to the attributes
map.
runtime:InvocationContext invocationContext = runtime:getInvocationContext();
invocationContext.attributes["SERVICE_NAME"] = "HelloService";
The following code snippet shows how to access the runtime:InvocationContext
and get the data from the attributes
map.
runtime:InvocationContext invocationContext = runtime:getInvocationContext();
string serviceName = runtime:getInvocationContext().attributes["SERVICE_NAME"].toString();
Sleep the current strand
The following is the code snippet for pausing the current strand for 1000 milliseconds.
runtime:sleep(1000);
