Method Details
-
getCondition
Gets the argument of this unary value operator.- Returns:
- The operator's argument.
-
setCondition
Sets the condition argument of this unary value operator.- Parameters:
condition- The (new) condition argument for this operator, must not be null.
-
visit
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 Exception
-
visitChildren
Description copied from interface:QueryModelNodeVisits the children of this node. The node callsQueryModelNode.visit(QueryModelVisitor)on all of its child nodes.- Specified by:
visitChildrenin interfaceQueryModelNode- Throws:
X extends Exception
-
replaceChildNode
Description copied from interface:QueryModelNodeReplaces one of the child nodes with a new node.- Specified by:
replaceChildNodein interfaceQueryModelNode- Parameters:
current- The current child node.replacement- The new child node.
-
equals
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 classObject
-
hashCode
public int hashCode() -
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 interfaceValueExpr- Overrides:
clonein classAbstractQueryModelNode- Returns:
- A deep clone of this query model node.
-
setResult
- Parameters:
result- The result to set.
-
getResult
- Returns:
- Returns the result.
-
setAlternative
- Parameters:
alternative- The alternative to set.
-
getAlternative
- Returns:
- Returns the alternative.
