QueryParameter

Return the name, main info, attribute info and named children

Return this Node with a Type assigned (if no other type has been seen for it yet) or a typed copy.

Names for the child nodes to show in AST dumps. Defaults to a numbered sequence starting at 0 but can be overridden by subclasses to produce more suitable names.

All child nodes of this node. Must be implemented by subclasses.

Apply a side-effecting function to all direct children from left to right. Note that

 n.childrenForeach(f) 

is equivalent to

 n.children.foreach(f) 

but can be implemented more efficiently in Node subclasses.

Check if this node has a type without marking the type as seen.

Rebuild this node and all children with their computed type. If this node already has a type, the children are only type-checked again if typeChildren is true. if retype is also true, the existing type of this node is replaced. If this node does not yet have a type, the types of all children are computed first.

Apply a mapping function to all children of this node and recreate the node with the new children. If all new children are identical to the old ones, this node is returned. If keepType is true, the type of this node is kept even when the children have changed.

The current type of this node.

Returns a string representation of the object.

The default representation is platform dependent.

Return this Node with no Type assigned (if it has not yet been observed) or an untyped copy.

Rebuild this node with new child nodes unless all children are identical to the current ones, in which case this node is returned.
