Class FullIdent


  • public final class FullIdent
    extends Object
    Represents a full identifier, including dots, with associated position information.

    Identifiers such as java.util.HashMap are spread across multiple AST nodes in the syntax tree (three IDENT nodes, two DOT nodes). A FullIdent represents the whole String (excluding any intermediate whitespace), which is often easier to work with in Checks.

      • createFullIdentBelow

        public static FullIdent createFullIdentBelow​(DetailAST ast)
        Creates a new FullIdent starting from the child of the specified node.
        Parameters:
        ast - the parent node from where to start from
        Returns:
        a FullIdent value
      • createFullIdent

        public static FullIdent createFullIdent​(DetailAST ast)
        Creates a new FullIdent starting from the specified node.
        Parameters:
        ast - the node to start from
        Returns:
        a FullIdent value
      • extractFullIdent

        private static void extractFullIdent​(FullIdent full,
                                             DetailAST ast)
        Recursively extract a FullIdent.

      • isArrayTypeDeclaration

        private static boolean isArrayTypeDeclaration​(DetailAST arrayDeclarator)
        Checks an `ARRAY_DECLARATOR` ast to verify that it is not a array initialization, i.e. 'new int [2][2]'. We do this by making sure that no 'EXPR' token exists in this branch.
        Parameters:
        arrayDeclarator - the first ARRAY_DECLARATOR token in the ast
        Returns:
        true if ast is an array type declaration

        Appends the brackets of an array type to a FullIdent.
        Parameters:
        full - the FullIdent to append brackets to
        ast - the type ast we are building a FullIdent for
