Method BindObject

src/util/binder.cpp:120–154

Binds all named parameters using the values found in the given object. The number of successfully bound parameters is returned. If a named parameter is missing from the object, an error is thrown. This should only be invoked once per instance.

	// If a named parameter is missing from the object, an error is thrown.
	// This should only be invoked once per instance.
