toSource
Description copied from class:AstNode
Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.Note: if the parser was in error-recovery mode, some AST nodes may have
null
children that are expected to be non-null
when no errors are present. In this situation, the behavior of thetoSource
method is undefined:toSource
implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse. -
visit
Error nodes are not visited during normal visitor traversals, but comply with theAstNode.visit(NodeVisitor)
interface.
