Example 36 with PackageInfo

use of org.ballerinalang.util.codegen.PackageInfo in project ballerina by ballerina-lang.

the class BLangFunctions method invokeEntrypointCallable.

/**
 * This method calls a program callable, considering it as an entry point callable. Which means, this callable will
 * be invoked as the first callable in a program, and after it is called, all the cleanup will be done for it to
 * exit from the program. That is, this callable will wait for the response to be fully available, and it will wait
 * till all the workers in the system to finish executing.
 * @param bLangProgram the program file
 * @param packageName the package the callable is residing
 * @param callableName the callable name
 * @param args the callable arguments
 * @return
