RDF::Query::Algebra::Sequence(3)
Algebra class for a sequence of algebra operations
VERSION
This document describes RDF::Query::Algebra::Sequence version 2.916.
METHODS
Beyond the methods documented below, this class inherits methods from the
RDF::Query::Algebra class.
- "new ( @patterns )"
-
Returns a new Sequence structure.
- "construct_args"
-
Returns a list of arguments that, passed to this class' constructor,
will produce a clone of this algebra pattern.
- "patterns"
-
Returns a list of patterns belonging to this sequence.
- "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.
- "definite_variables"
-
Returns a list of the variable names that will be bound after evaluating this algebra expression.
- "clone"
-
- "bind_variables ( \%bound )"
-
Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.
- "check_duplicate_blanks"
-
Returns true if blank nodes respect the SPARQL rule of no blank-label re-use
across BGPs, otherwise throws a RDF::Query::Error::QueryPatternError exception.
