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
-
getVariables
public VariableDeclaration getVariables()
Returns variable list
-
setVariables
public void setVariables(VariableDeclaration variables)
Sets variable list. Sets list parent to this node.- Throws:
java.lang.IllegalArgumentException- if variables isnull
-
getBody
public 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
-
setBody
public 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 benull.
-
getLp
public int getLp()
Returns left paren position, -1 if missing
-
setLp
public void setLp(int lp)
Sets left paren position
-
getRp
public int getRp()
Returns right paren position, -1 if missing
-
setRp
public void setRp(int rp)
Sets right paren position
-
setParens
public void setParens(int lp, int rp)Sets both paren positions
-
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.
-
visit
public void visit(NodeVisitor v)
Visits this node, the variable list, and if present, the body expression or statement.
