Class ASTLambdaExpression

    • Method Detail

      • getFunctionalMethod

        public JMethodSig getFunctionalMethod()
        Returns the method that is overridden in the functional interface. E.g. in stringStream.map(s -> s.isEmpty()), this is java.util.function.Function#apply(java.lang.String) -> java.lang.Boolean

      • isBlockBody

        public boolean isBlockBody()
        Returns true if this lambda has a block for body.
      • isExpressionBody

        public boolean isExpressionBody()
        Returns true if this lambda has an expression for body.
      • getBlock

        public @Nullable ASTBlock getBlock()
        Returns the body of this expression, if it is a block.
      • getExpression

        public @Nullable ASTExpression getExpression()
        Returns the body of this expression, if it is an expression.
      • getBlockBody

        public @Nullable ASTBlock getBlockBody()

      • acceptVisitor

        protected <P,​R> R acceptVisitor​(JavaVisitor<? super P,​? extends R> visitor,
                                              P data)
      • getParenthesisDepth

        public int getParenthesisDepth()
        Description copied from interface: ASTExpression
        Returns the number of parenthesis levels around this expression. If this method returns 0, then no parentheses are present.

        E.g. the expression (a + b) is parsed as an AdditiveExpression whose parenthesisDepth is 1, and in ((a + b)) it's 2.

        This is to avoid the parentheses interfering with analysis. Parentheses already influence parsing by breaking the natural precedence of operators. It would mostly hide false positives to make a ParenthesizedExpr node, because it would make semantically equivalent nodes have a very different representation.

        On the other hand, when a rule explicitly cares about parentheses, then this attribute may be used to find out whether parentheses were mentioned, so no information is lost.

      • getConstValue

        public @Nullable Object getConstValue()
        Description copied from interface: ASTMemberValue
        Returns the constant value of this node, if this is a constant expression. Otherwise, or if some references couldn't be resolved, returns null. Note that null is not a constant value, so this method's returning null is not a problem. Note that annotations are not given a constant value by this implementation.

      • getPreferredReportLocation

        protected @Nullable JavaccToken getPreferredReportLocation()
        Temporary hack so that classes and methods are reported on their identifier token and not the first annotation. Changes about text documents make that more general, in a future PR.
