ATLAS 3.9.2 (Development branch)
The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK. License: BSD License (original)Changes:
Improved Core2 performance, particularly for 32 bit and/or single precision. The Core2Duo arch name has been changed to Core2. The cycle of dependencies in L1 Makefiles has been fixed. Compile problems for architectures without cacheline flush in assembly have been fixed. An error in configure caused by a change in CPUID usage has been fixed. Missing f77 wrappers for GERQF and GEQLF have been added. CPP division is avoided in assembly on Solaris due to a binutils/Solaris bug.Image

rdf::query::algebra

RDF::Query::Algebra(3pm)				User Contributed Perl Documentation				  RDF::Query::Algebra(3pm)

NAME

       RDF::Query::Algebra - Base class for Algebra expressions

VERSION

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

METHODS

       "potentially_bound"
	   Returns a list of the variable names used in this algebra expression that will bind values during execution.

       "referenced_blanks"
	   Returns a list of the blank node names used in this algebra expression.

       "referenced_functions"
	   Returns a list of the Function URIs used in this algebra expression.

       "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.

       "qualify_uris ( \%namespaces, $base_uri )"
	   Returns a new algebra pattern where all referenced Resource nodes representing QNames (ns:local) are qualified using the supplied
	   %namespaces.

       "bind_variables ( \%bound )"
	   Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.

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

       "subpatterns_of_type ( $type [, $block] )"
	   Returns a list of Algebra patterns 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 algebra object if it matches
	   $type, and is generated in infix order.

       "from_sse ( $sse, \%context )"
	   Given an SSE serialization, returns the corresponding algebra expression.

FUNCTIONS

       "triple ( $subj, $pred, $obj )"
	   Returns a RDF::Query::Algebra::Triple object with the supplied node objects.

       "bgp ( @triples )"
	   Returns a RDF::Query::Algebra::BasicGraphPattern object with the supplied triples.

       "ggp ( @patterns )"
	   Returns a RDF::Query::Algebra::GroupGraphPattern object with the supplied algebra patterns.
