[Coldbox 7.4.2] Providers Namespace and Constructor/Init Arguments

Communities ColdBox HMVC

When using the provider: injection is there a way to specify constructor/init arguments to the resulting object?

For example:

property name="gatewayResult" inject="provider:GatewayResult";

// Get a new instance of the GatewayResult object
private GatewayResult function getGatewayResult() {
    return gatewayResult.$get();
}

Let’s now assume the GatewayResult needs a specific constructor argument, is there a way to pass that when instantiating it via the $get() method?

This currently does not work:

gatewayResult.$get( name="foo" );

You might be wondering why I’m calling $get() in the first place. Well, sometimes you may need to get a new instance of the object, but not call any methods on it, right away. For example:

var result = getGatewayResult();

if ( success ) {
  return result.success( ... );
} 

return result.error( ... );

I took a look at the code in /coldbox/system/ioc/Provider.cfc and don’t see a way to add constructor arguments.

Workaround 1:
Don’t use constructor arguments, and instead explicitly call methods after instantiation like this:

private GatewayResult function getGatewayResult() {
    var result = gatewayResult.$get();
    result.setName( "foo" );
    return result;
}

Workaround 2
Don’t use the provider: namespace and instead use Wirebox’s getInstance()

return wirebox.getInstance( name=“GatewayResult”, initArguments={ name="foo" } )
