getBindingNames
public java.util.Set<java.lang.String> getBindingNames()
Description copied from interface:TupleExprGets the names of the bindings that are, or can be, returned by this tuple expression when it is evaluated.- Specified by:
getBindingNamesin interfaceTupleExpr- Returns:
- A set of binding names.
-
getAssuredBindingNames
public java.util.Set<java.lang.String> getAssuredBindingNames()
Description copied from interface:TupleExprGets the names of the bindings that are guaranteed to be present in the results produced by this tuple expression.- Specified by:
getAssuredBindingNamesin interfaceTupleExpr- Returns:

-
visit
public <X extends java.lang.Exception> void visit(QueryModelVisitor<X> visitor) throws X extends java.lang.Exception
Description copied from interface:QueryModelNodeVisits this node. The node reports itself to the visitor with the proper runtime type.- Specified by:
visitin interfaceQueryModelNode- Throws:
X extends java.lang.Exception
-
visitChildren

getSignaturein interfaceQueryModelNode- Overrides:
getSignaturein classAbstractQueryModelNode- Returns:
- The node's signature, e.g. SLICE (offset=10, limit=10).
-
equals
public boolean equals(java.lang.Object other)
Description copied from interface:QueryModelNodeReturns true if this query model node and its children are recursively equal to o and its children.- Specified by:
equalsin interfaceQueryModelNode- Overrides:
equalsin classjava.lang.Object
-
hashCode
public int hashCode()
- Overrides:
hashCodein classjava.lang.Object
-
clone
public TupleFunctionCall clone()
Description copied from interface:QueryModelNodeReturns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.- Specified by:
clonein interfaceQueryModelNode- Specified by:
clonein interfaceTupleExpr- Overrides:
clonein classAbstractQueryModelNode- Returns:
- A deep clone of this query model node.
