The direct child trees of this tree.
The direct child trees of this tree. EmptyTrees are always omitted. Lists are flattened.
Apply pf' to each subtree on which the function is defined and collect the results.

fact is remembered so that resetAllAttrs will snap back.

Make a copy of this tree, keeping all attributes, except that all positions are focused (so nothing in this tree will be found when searching by position).
The universal equality method defined in AnyRef
.
Tests whether two trees are structurall equal.
Tests whether two trees are structurall equal.
Note that ==
on trees is reference equality.

If pf
is defined for a given subtree, call super.
If pf
is defined for a given subtree, call super.traverse(pf(tree)),
otherwise super.traverse(tree).
Extracts free term symbols from a tree that is reified or contains reified subtrees.

The canonical way to test if a Tree represents a type.
Sets the tree's type to the result of the given function.
Sets the tree's type to the result of the given function. If the type is null, it remains null - the function is not called.

Note that symbol is fixed as null at this level.
Note that symbol is fixed as null at this level. In SymTrees, it is overridden and implemented with a var, initialized to NoSymbol.
Trees which are not SymTrees but which carry symbols do so by
overriding def symbol
to forward it elsewhere. Examples:
Super(qual, _) // has qual's symbol Apply(fun, args) // has fun's symbol TypeApply(fun, args) // has fun's symbol AppliedTypeTree(tpt, args) // has tpt's symbol TypeTree(tpe) // has tpe's typeSymbol, if tpe != null
Attempting to set the symbol of a Tree which does not support it will induce an exception.
