Get value from .NET Framework DLL in Perl

The GetValue method is used to retrieve the result of an operation performed by the Javonet API.

# use activate only once in your app

# create called runtime context
my $called_runtime = Javonet->in_memory()->clr();

# construct an invocation context - this invocationContext in non-materialized 
my $invocation_context = $called_runtime->get_type("System.Math")->invoke_static_method("Abs", -50);

# execute invocation context - this will materialize the invocationContext
my $response = $invocation_context->execute();

# get value from response
my $result = $response->get_value();

# write result to console

Commands are becoming nested through each invocation of methods on Invocation Context. Each invocation triggers the creation of new Invocation Context instance wrapping the current command with new parent command valid for invoked method.

Developer can decided on any moment of the materialization for the context taking full control of the chunks of the expression being transferred and processed on target runtime.
