Class OutputModelWalker
java.lang.Object
org.antlr.v4.codegen.OutputModelWalker
Convert an output model tree to template hierarchy by walking
the output model. Each output model object has a corresponding template
of the same name. An output model object can have nested objects.
We identify those nested objects by the list of arguments in the template
definition. For example, here is the definition of the parser template:
Parser(parser, scopes, funcs) ::= <<...>>
The first template argument is always the output model object from which
this walker will create the template. Any other arguments identify
the field names within the output model object of nested model objects.
So, in this case, template Parser is saying that output model object
Parser has two fields the walker should chase called a scopes and funcs.
This simple mechanism means we don't have to include code in every
output model object that says how to create the corresponding template.
