Method Details
-
getOperator
This method returns the operator of this expression.- Returns:
- the operator of this expression.
-
getLeftExpression
This method returns the left hand side expression of the operator.- Returns:
- the left hand side expression of the operator.
-

getChildNodes
Description copied from interface:ISemanticNode
This method returns an array containing the child nodes. The order of the child nodes in the array is not defined, and the array may be empty for nodes that do not have child nodes.- Returns:
- Array containing the child nodes of this node.
-
collectScopedObjects
Description copied from interface:ISemanticNode
This method may be used to collect the names of the objects that need to be in scope in order to evaluate the expression of this node. The object passed to the method will be enriched with the names of the objects that need to be in scope.- Parameters:
resultSet
- The object that should be used to add the names of the objects that need to be in scope to.
-
visit
Description copied from interface:ISemanticNode
This method allows a type safe visitation of the node. The visit method will not invoke the visitor for any child nodes.- Parameters:
visitor
- The visitor that should be invoked for this node.
