Class TryStatement

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

    public class TryStatement
    extends AstNode
    Try/catch/finally statement. Node type is Token.TRY.

    TryStatement :
            try Block Catch
            try Block Finally
            try Block Catch Finally
     Catch :
            catch ( Identifier ) Block
     Finally :
            finally Block

      • getTryBlock

        public AstNode getTryBlock()
      • setTryBlock

        public void setTryBlock​(AstNode tryBlock)
        Sets try block. Also sets its parent to this node.
        IllegalArgumentException - } if tryBlock is null
      • getCatchClauses

        public List<CatchClause> getCatchClauses()
        Returns list of CatchClause nodes. If there are no catch clauses, returns an immutable empty list.
      • setCatchClauses

        public void setCatchClauses​(List<CatchClause> catchClauses)
        Sets list of CatchClause nodes. Also sets their parents to this node. May be null. Replaces any existing catch clauses for this node.
      • addCatchClause

        public void addCatchClause​(CatchClause clause)
        Add a catch-clause to the end of the list, and sets its parent to this node.
        IllegalArgumentException - } if clause is null
      • getFinallyBlock

        public AstNode getFinallyBlock()
        Returns finally block, or null if not present
      • setFinallyBlock

        public void setFinallyBlock​(AstNode finallyBlock)
        Sets finally block, and sets its parent to this node. May be null.
      • getFinallyPosition

        public int getFinallyPosition()
        Returns position of finally keyword, if present, or -1
      • setFinallyPosition

        public void setFinallyPosition​(int finallyPosition)
        Sets position of finally keyword, if present, or -1
      • 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.

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

        public void visit​(NodeVisitor v)
        Visits this node, then the try-block, then any catch clauses, and then any finally block.
        Specified by:
        visit in class AstNode
        v - the object to call with this node and its children
