 public class LetNode extends Scope AST node for let statements and expressions. Node type isToken.LETorToken.LETEXPR.LetStatement: let ( VariableDeclarationList ) Block LetExpression: let ( VariableDeclarationList ) ExpressionNote that standalone let-statements with no parens or body block, such aslet x=6, y=7;, are represented as aVariableDeclarationnode of typeToken.LET, wrapped with anExpressionStatement.

Method Detail- 
getVariablespublic VariableDeclaration getVariables() Returns variable list
 - 
setVariablespublic void setVariables(VariableDeclaration variables) Sets variable list. Sets list parent to this node.- Throws:
- java.lang.IllegalArgumentException- if variables is- null
 
 - 
getBodypublic AstNode getBody() Returns body statement or expression. Body isnullif the form of the let statement is similar to a VariableDeclaration, with no curly-brace. (This form is used to define let-bound variables in the scope of the current block.)- Returns:
- the body form
 
 - 
setBodypublic void setBody(AstNode body) Sets body statement or expression. Also sets the body parent to this node.- Parameters:
- body- the body statement or expression. May be- null.
 
 - 
getLppublic int getLp() Returns left paren position, -1 if missing
 - 
setLppublic void setLp(int lp) Sets left paren position
 - 
getRppublic int getRp() Returns right paren position, -1 if missing
 - 
setRppublic void setRp(int rp) Sets right paren position
 - 
setParenspublic void setParens(int lp, int rp)Sets both paren positions
 - 
toSourcepublic 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.
 - 
visitpublic void visit(NodeVisitor v) Visits this node, the variable list, and if present, the body expression or statement.
