Class CatchClause

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

    public class CatchClause
    extends AstNode
    Node representing a catch-clause of a try-statement. Node type is Token.CATCH.

      • getVarName

        public Name getVarName()
        Returns catch variable node
        catch variable
      • setVarName

        public void setVarName​(Name varName)
        Sets catch variable node, and sets its parent to this node.
        varName - catch variable
        IllegalArgumentException - if varName is null
      • getCatchCondition

        public AstNode getCatchCondition()
        Returns catch condition node, if present
        catch condition node, null if not present
      • setCatchCondition

        public void setCatchCondition​(AstNode catchCondition)
        Sets catch condition node, and sets its parent to this node.
        catchCondition - catch condition node. Can be null.
      • getBody

        public Block getBody()
        Returns catch body
      • setBody

        public void setBody​(Block body)
        Sets catch body, and sets its parent to this node.
        IllegalArgumentException - if body is null
      • getLp

        public int getLp()
        Returns left paren position
      • setLp

      • setRp

        public void setRp​(int rp)
        Sets right paren position
      • setParens

        public void setParens​(int lp,
                              int rp)
        Sets both paren positions
      • getIfPosition

        public int getIfPosition()
        Returns position of "if" keyword
        position of "if" keyword, if present, or -1
      • setIfPosition

        public void setIfPosition​(int ifPosition)
        Sets position of "if" keyword
        ifPosition - position of "if" 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, the catch var name node, the condition if non-null, and the catch body.
        Specified by:
        visit in class AstNode
        v - the object to call with this node and its children
