Class ForLoop

  • All Implemented Interfaces:
    Comparable<AstNode>, Iterable<Node>

    public class ForLoop
    extends Loop
    C-style for-loop statement. Node type is Token.FOR.

      • setInitializer

        public void setInitializer​(AstNode initializer)
        Sets loop initializer expression, and sets its parent to this node. Virtually any expression can be in the initializer, so no error-checking is done other than a null-check.
        initializer - loop initializer. Pass an EmptyExpression if the initializer is not specified.
        IllegalArgumentException - if condition is null
      • getCondition

        public AstNode getCondition()
        Returns loop condition
      • setCondition

        public void setCondition​(AstNode condition)
        Sets loop condition, and sets its parent to this node.
        condition - loop condition. Pass an EmptyExpression if the condition is missing.
        IllegalArgumentException - } if condition is null
      • getIncrement

        public AstNode getIncrement()
        Returns loop increment expression
      • setIncrement

        public void setIncrement​(AstNode increment)
        Sets loop increment expression, and sets its parent to this node.
        increment - loop increment expression. Pass an EmptyExpression if increment is null.
        IllegalArgumentException - } if increment is null
      • toSource

        public String toSource​(int depth)
        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 the toSource 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.

        toSource in class Scope
        depth - the current recursion depth, typically beginning at 0 when called on the root node.
      • visit

        public void visit​(NodeVisitor v)
        Visits this node, the initializer expression, the loop condition expression, the increment expression, and then the loop body.
        visit in class Scope
        v - the object to call with this node and its children
