Field Detail

graphPattern

protected com.bigdata.rdf.sail.sparql.GroupGraphPattern graphPattern

Used to manage collection and nesting of graph patterns. This is mostly handled by GroupGraphPatternBuilder.

Note: Both ASTExistsFunc and ASTNotExistsFunc have an inner graph pattern by they appear within value expressions.

Unwrap an ASTInfix node, returning the inner FunctionNode constructed for it.

Note: Sesame has picked up the notion of an ASTInfix node, but they are handling it slightly differently.

public final FunctionNode visit(ASTIn node,

"IN" and "NOT IN" are infix notation operators. The syntax for "IN" is [NumericExpression IN ArgList]. However, the IN operators declared by the FunctionRegistry require that the outer NumericExpression is their first argument. The function registry optimizes several different cases, including where the set is empty, where it has one member, and where the members of the set are constants and the outer expression is a variable.

Aggregate value expressions in GROUP BY clause. The content of this production can be a VarNode, AssignmentNode, or FunctionNode (which handles both built-in functions and extension functions). However, we always wrap it as an AssignmentNode and return that. A VarNode will just bind itself. A bare FunctionNode will bind an anonymous variable.

TODO additional scalar values (sparql.jjt specifies "separator EQ" as a constant in the grammar, but we support additional scalar values for GROUP_CONCAT. Also, the grammar is permissive and allows Expression for separator rather than a quoted string (per the W3C draft).
