new ( $query_pattern,
\@construct_triples )
Returns a new Sort structure.
construct_args
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
pattern
Returns the pattern used to produce the variable bindings used in graph construction.
triples
Returns an ARRAY ref of triples to be used in graph construction.
sse
Returns the SSE string for this algebra expression.
as_sparql
Returns the SPARQL string for this algebra expression.
as_hash
Returns the query as a nested set of plain data structures (no objects).
type
Returns the type of this algebra expression.
referenced_variables
Returns a list of the variable names used in this algebra expression.
potentially_bound
Returns a list of the variable names used in this algebra expression that will bind values during execution.
