getOwner
- Specified by:
getOwner
in interfaceExclusiveTupleExpr
- Returns:
- the owner for this expression
-
clone
Description copied from interface:QueryModelNode
Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.- Specified by:
clone
in interfaceQueryModelNode
- Specified by:
clone
in interfaceTupleExpr
- Overrides:
clone
in classArbitraryLengthPath
- Returns:
- A deep clone of this query model node.
-
toQueryString
Description copied from interface:ExclusiveTupleExprRenderer
Returns a SPARQL string representation of this expression that can be inserted into a SELECT query.Implementations are required to create a valid query string for this expression where the given bindings are inserted.
- Specified by:
toQueryString
in interfaceExclusiveTupleExprRenderer
- Parameters:
varNames
- the set of resulting (unbound) variables from this expressionbindings
- the optional input bindings- Returns:
- the query string part
-
toQueryAlgebra
Description copied from interface:ExclusiveTupleExprRenderer
Returns a SPARQL algebra representation of this expression that can be inserted into a SELECTTupleExpr
Implementations are required to create a new equivalent expression or clone, where any provided input bindings are inserted. The free variable names after insertion need to be added to the provided set.
- Specified by:
toQueryAlgebra
in interfaceExclusiveTupleExprRenderer
- Parameters:
varNames
- the set of resulting (unbound) variables from this expressionbindings
- the input bindings that need to be inserted- Returns:
- the algebra expression
-
getFreeVars
- Specified by:
getFreeVars
in interfaceVariableExpr
- Returns:
- a list of free (i.e. unbound) variables in this expression
-
getQueryInfo
Description copied from interface:QueryRef
Retrieve the attached query information of the tuple expression- Specified by:
getQueryInfo
in interfaceQueryRef
- Returns:
- the
QueryInfo
