This document describes RDF::Trine::Iterator::Boolean version 1.019

Beyond the methods documented below, this class inherits methods from the RDF::Trine::Iterator class. "new ( \@results, %args )" "new ( \&results, %args )" Returns a new SPARQL Result interator object. Results must be either an reference to an array containing results or a CODE reference that acts as an iterator, returning successive items when called, and returning undef when the iterator is exhausted. $type should be one of: bindings, boolean, graph. "is_boolean" Returns true if the underlying result is a boolean value. "as_string ( $max_size [, \$count] )" Returns a string serialization of the stream data. "as_xml ( $max_size )" Returns an XML serialization of the stream data. "print_xml ( $fh, $max_size )" Prints an XML serialization of the stream data to the filehandle $fh. "as_json ( $max_size )" Returns a JSON serialization of the stream data. "construct_args" Returns the arguments necessary to pass to the stream constructor _new to re-create this stream (assuming the same closure as the first
