NAME

       RDF::Query::Parser - Parser base class

VERSION

       This document describes RDF::Query::Parser version 2.908.

METHODS

       "new_literal ( $literal, $language, $datatype )"
	   Returns a new literal structure.

       "new_variable ( $name )"
	   Returns a new variable structure.

       "new_blank ( $name )"
	   Returns a new blank node structure.

       "new_uri ( $uri )"
	   Returns a new variable structure.

       "new_triple ( $s, $p, $o )"
	   Returns a new triple structure.

       "new_unary_expression ( $operator, $operand )"
	   Returns a new unary expression structure.

       "new_binary_expression ( $operator, @operands )"
	   Returns a new binary expression structure.

       "new_function_expression ( $function, @operands )"
	   Returns a new function expression structure.

       "new_alias_expression ( $alias, $expression )"
	   Returns a new alias expression structure.

       "new_filter ( $filter_expr, $pattern )"
	   Returns a new filter structure.

       "fail ( $error )"
	   Sets the current error to $error.

	   If the parser is in commit mode (by calling "set_commit"), throws a RDF::Query::Error::ParseError object. Otherwise returns "undef".

       "error ()"
	   Returns the last error the parser experienced.

NAME

       RDF::Query::Algebra::Limit - Algebra class for limiting query results

VERSION

       This document describes RDF::Query::Algebra::Limit version 2.908.

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.

       "new ( $pattern, $limit )"
	   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 to be sorted.

       "limit"
	   Returns the limit number of the pattern.

       "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.

       "is_solution_modifier"
	   Returns true if this node is a solution modifier.
