Method Detail

addressValue	back to summary
private static final long addressValue(ThreadContext context, IRubyObject value) Extracts the primitive value from a Ruby object. This is similar to Util.longValue(), except it won't throw exceptions for invalid values. Parameters value:IRubyObject The Ruby object to convert Returns:long a java long value.
