new ( $expression,
$pattern )Returns a new Filter structure.
construct_argsReturns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
exprReturns the filter expression.
patternReturns the filter pattern.
sseReturns the SSE string for this alegbra expression.
as_sparqlReturns the SPARQL string for this alegbra expression.
typeReturns the type of this algebra expression.
referenced_variablesReturns a list of the variable names used in this algebra expression.
definite_variablesReturns a list of the variable names that will be bound after evaluating this algebra expression.
fixup ( $query,
$bridge,
$base,
\%namespaces )Returns a new pattern that is ready for execution using the given bridge. This method replaces generic node objects with bridge-native objects.
