Basic Examples
(1)
An infix node built literally flattens the whole run into one node with three children:
1+2+3
In[1]:=
 | InfixNode |
 | LeafNode |
| LeafNode |
| LeafNode |
Out[1]=
InfixNode[+,{LeafNode[Integer,1,],LeafNode[Integer,2,],LeafNode[Integer,3,]},]
The calculator does not flatten: the same parses to nested nodes, not an :
1+2+3
InfixNode
In[2]:=
| CalculatorAST |
Out[2]=
ContainerNode[String,{BinaryNode[+,{BinaryNode[+,{LeafNode[Integer,1,Source{{1,1},{1,2}}],LeafNode[Integer,2,Source{{1,3},{1,4}}]},Source{{1,1},{1,4}}],LeafNode[Integer,3,Source{{1,5},{1,6}}]},Source{{1,1},{1,6}}]},Source{{1,1},{1,6}}]
