NAME

       RDF::Query::VariableBindings - Variable bindings

VERSION

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

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Trine::VariableBindings class.

       "new ( \%bindings )"
       "sse ( \%context, $indent )"
       "explain"
	   Returns a string serialization of the variable bindings appropriate for display on the command line.

NAME

       RDF::Query::Plan - Executable query plan nodes.

VERSION

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

METHODS

       "new"
       "execute ( $execution_context )"
       "next"
       "get_all"
	   Returns all remaining rows.

       "close"
       "state ( [ $state ] )"
	   Returns the current state of the plan (either READY, OPEN, or CLOSED).  If $state is provided, updates the plan to a new state.

       "logging_keys"
       "explain"
	   Returns a string serialization of the query plan appropriate for display on the command line.

       "sse"
       "serialize"
	   Return a serialization of the query plan.

       "delegate"
	   Returns the delegate object if available.

       "referenced_variables"
	   Returns a list of variable names that are referenced by this plan.

       "as_iterator ( $context )"
	   Returns an RDF::Trine::Iterator object for the current (already executed) plan.

       "is_update"
	   Returns true if the plan represents an update operation.

       "label ( $label => $value )"
	   Sets the named $label to $value for this plan object.  If no $value is given, returns the current label value, or undef if none exists.

       "graph_labels"
       "generate_plans ( $algebra, $execution_context, %args )"
	   Returns a list of equivalent query plan objects for the given algebra object.

       "plan_node_name"
	   Returns the string name of this plan node, suitable for use in serialization.

       "plan_prototype"
	   Returns a list of scalar identifiers for the type of the content (children) nodes of this plan node. These identifiers are recognized:

	    * 'A' - An RDF::Query::Algebra object
	    * 'b' - A boolean integer value (0 or 1)
	    * 'E' - An expression (either an RDF::Query::Expression object or an RDF node)
	    * 'i' - An integer
	    * 'J' - A valid Project node (an RDF::Query::Expression object or an Variable node)
	    * 'N' - An RDF node
	    * 'P' - A RDF::Query::Plan object
	    * 'q' - A RDF::Query object
	    * 'Q' - An RDF::Trine::Statement::Quad object
	    * 's' - A string
	    * 'T' - An RDF::Trine::Statement object
	    * 'u' - A valid URI string
	    * 'V' - A variable binding set (an object of type RDF::Query::VariableBindings)
	    * 'w' - A bareword string
	    * 'W' - An RDF node or wildcard ('*')
	    * '*X' - A list of X nodes (where X is another identifier scalar)
	    * 'X' - An array reference of X nodes (where X is another identifier scalar)

       "plan_node_data"
	   Returns the data for this plan node that corresponds to the values described by the signature returned by "plan_prototype".

       "subplans_of_type ( $type [, $block] )"
	   Returns a list of Plan objects matching $type (tested with "isa").  If $block is given, then matching stops descending a subtree if the
	   current node is of type $block, continuing matching on other subtrees.  This list includes the current plan object if it matches $type,
	   and is generated in infix order.
