An array access expression. 

 ArrayAccess ::=  Expression "["  Expression "]"

  • Field Details

  • Method Details

    • getQualifier

      public @NonNull ASTExpression getQualifier()
      Returns the expression to the left of the "[". This can never be a type, and is never ambiguous.
      Specified by:
      getQualifier in interface QualifiableExpression

    • getIndexExpression

      public ASTExpression getIndexExpression()
      Returns the expression within the brackets.

    • 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.

      Specified by:
      getParenthesisDepth in interface ASTExpression

    • getConstFoldingResult

      public @NonNull ASTExpression.ConstResult getConstFoldingResult()
      Description copied from interface: ASTExpression
      Returns the result of constant folding on this expression. This may find a constant value for more than strict compile-time constants. See ASTExpression.ConstResult.
      Specified by:
      getConstFoldingResult in interface ASTExpression

    • buildConstValue

      @Deprecated protected @Nullable Object buildConstValue()
      Deprecated.
      Since 7.12.0. Kept for binary compatibility. This method should have been package-private from the start. Use ASTExpression.getConstValue() or ASTExpression.getConstFoldingResult() instead.

    • getTypeMirror

      public @NonNull JTypeMirror getTypeMirror()
      Description copied from interface: TypeNode
      Returns the compile-time type of this node. For example, for a string literal, returns the type mirror for String, for a method call, returns the return type of the call, etc.

      This method ignores conversions applied to the value of the node because of its context. For example, in 1 + "", the numeric literal will have type int, but it is converted to String by the surrounding concatenation expression. Similarly, in Collections.singletonList(1), the ASTNumericLiteral node has type int, but the type of the method formal is Integer, and boxing is applied at runtime. Possibly, an API will be added to expose this information.

      Specified by:
      getTypeMirror in interface TypeNode
      Returns:
      The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.
