ProtectedaggregateAggregates the results of visiting multiple children of a node. After
either all children are visited or #shouldVisitNextChild returns
false, the aggregate value is returned as the result of
#visitChildren.
The default implementation returns nextResult, meaning
#visitChildren will return the result of the last child visited
(or return the initial value if the node has no children).
The previous aggregate value. In the default
implementation, the aggregate value is initialized to
#defaultResult, which is passed as the aggregate argument
to this method after the first child node is visited.
The result of the immediately preceeding call to visit a child node.
The updated aggregate result.
ProtecteddefaultGets the default value returned by visitor methods. This value is returned by the default implementations of #visitTerminal visitTerminal, #visitErrorNode visitErrorNode. The default implementation of #visitChildren visitChildren initializes its aggregate result to this value.
The default value returned by visitor methods.
ProtectedshouldThis method is called after visiting each child in
#visitChildren. This method is first called before the first
child is visited; at that point currentResult will be the initial
value (in the default implementation, the initial value is returned by a
call to #defaultResult. This method is not called after the last
child is visited.
The default implementation always returns true, indicating that
visitChildren should only return after all children are visited.
One reason to override this method is to provide a "short circuit"
evaluation option for situations where the result of visiting a single
child has the potential to determine the result of the visit operation as
a whole.
The RuleNode whose children are currently being visited.
The current aggregate result of the children visited to the current point.
true to continue visiting children. Otherwise return
false to stop visiting children and immediately return the
current aggregate result from #visitChildren.

{@inheritDoc }
The default implementation initializes the aggregate result to
#defaultResult defaultResult(). Before visiting each child, it
calls #shouldVisitNextChild shouldVisitNextChild; if the result
is false no more children are visited and the current aggregate
result is returned. After visiting a child, the aggregate result is
updated by calling #aggregateResult aggregateResult with the
previous aggregate result and the result of visiting the child.
The default implementation is not safe for use in visitors that modify the tree structure. Visitors that modify the tree should override this method to behave properly in respect to the specific algorithm in use.
