(inner) instantiateAndInitialize(accessorNames)

If there are one or more arguments after duktapeHostInvoke.js, then assume that each argument names a file defining an accessor. Each accessor is instantiated and initialized.

See duktapeHostInvoke.js for a file that requires duktapeHost.js and then invokes this method.

Sample usage:

duktapeHostInvoke.js contains:

var commonHost = require('./duktapeHost.js');
// Remove "node.js" from the array of command line arguments.
process.argv.shift();
// Remove "duktapeHostInvoke.js" from the array of command line arguments.
process.argv.shift();
instantiateAndInitialize(process.argv);

To invoke:

  node duktapeHostInvoke.js test/TestComposite
Parameters:
Name Type Description
accessorNames

An array of accessor names in a format suitable for getAccessorCode(name).
