NAME¶
RDF::Query::Algebra::GroupGraphPattern - Algebra class for GroupGraphPattern
patterns
VERSION¶
This document describes RDF::Query::Algebra::GroupGraphPattern version 2.908.
METHODS¶

RDF::Query::Algebra class.
- "new ( @graph_patterns )"
- Returns a new GroupGraphPattern structure.
- "construct_args"
- Returns a list of arguments that, passed to this class'
constructor, will produce a clone of this algebra pattern.
- "patterns"

for display on the command line.
- "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).
- "as_spin ( $model )"
