public class Jump extends AstNode
Used for code generation. During codegen, the AST is transformed into an Intermediate Representation (IR) in which loops, ifs, switches and other control-flow statements are rewritten as labeled jumps. If the parser is set to IDE-mode, the resulting AST will not contain any instances of this class.

toSource
public java.lang.String toSource(int depth)
Description copied from class:AstNodeEmits 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
nullchildren that are expected to be non-nullwhen no errors are present. In this situation, the behavior of thetoSourcemethod is undefined:toSourceimplementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.
