NAME

       RDF::Redland::QueryResults - Redland RDF Syntax Query Results Class

SYNOPSIS

	 use RDF::Redland;

	 ...
	 my $query=new RDF::Redland::Query("query string", undef, undef, "sparql");
	 my $results=$model->query_execute($query);
	 # or my $results=$query->execute($model);
	 while(!$results->finished) {
	   for (my $i=0; $i < $results->bindings_count(); $i++) {
	     my $name=$results->binding_name($i);
	     my $value=$results->binding_value($i);
	     # ... do something with the results
	   }
	   $results->next_result;
	 }

       The $results in the example is an object of class RDF::Redland::QueryResults.

DESCRIPTION

       This class represents queries of various syntaxes over an RDF::Redland::Model returning a sequence of results that bind variable names to
       RDF::Redland::Node values.

CONSTRUCTOR

       There are no public constructors.

METHODS

       count
	   Return the number of current results from the query.

       finished
	   Return non-0 if the results have been exhausted.

       binding_name INDEX
	   Get the name of variable binding INDEX in the array of variable names.

       binding_names
	   Get the names all of the variable bindings as an array.

       binding_value INDEX
	   Get the value of the variable binding INDEX in the current query result.

       binding_values
	   Get the values of all of the variable bindings in the current query result.

       binding_value_by_name NAME
	   Get the value of the variable binding NAME in the current query result.

       bindings

       bindings_count
	   Return the number of variable bindings.

       next_result
	   Move to the next query result.

       as_stream

       to_string [FORMAT-URI [BASE-URI]]
	   Serialize to a string syntax in format FORMAT-URI using the optional BASE-URI.  The default format when none is given is determined by
	   librdf_query_results_to_string.

       is_bindings
	   Return non-0 if the query results format is variable bindings

       is_boolean
	   Return non-0 if the query results format is a boolean
