Visit children of an ANTLR parse tree node and add them as children of the current AST node. Assumes that the default implementation of visit returns null making it possible to override it only for interesting nodes.

Type Parameters:

V - the visitor's type

Parameters:

visitor - the visitor implementation

node - the current parse tree node

parent - the AST node to which children will be added

location

public static Location location(org.antlr.v4.runtime.ParserRuleContext context)

Create a Location instance from an ANTLR rule context.

Parameters:

context - the current ANTLR context
