      • STATIC_INIT

        public static final int STATIC_INIT
        A static initialization block. Zero or more static initializers may be children of the object block of a class or enum declaration (interfaces cannot have static initializers). The first and only child is a statement list.

        For Example:

         static {
           num = 10;
         }
         

        parses as:

         STATIC_INIT -> STATIC_INIT
          `--SLIST -> {
              |--EXPR -> EXPR
              |   `--ASSIGN -> =
              |       |--IDENT -> num
              |       `--NUM_INT -> 10
              |--SEMI -> ;
              `--RCURLY -> }

      • PACKAGE_DEF

        public static final int PACKAGE_DEF
        The package declaration. This is optional, but if it is included, then there is only one package declaration per source file and it must be the first non-comment in the file. A package declaration may be annotated in which case the annotations comes before the rest of the declaration (and are the first children).

        For example:

           package com.puppycrawl.tools.checkstyle.api;
         

        parses as:

         PACKAGE_DEF -> package
         |--ANNOTATIONS -> ANNOTATIONS
         |--DOT -> .
         |   |--DOT -> .
         |   |   |--DOT -> .
         |   |   |   |--DOT -> .
         |   |   |   |   |--IDENT -> com
         |   |   |   |   `--IDENT -> puppycrawl
         |   |   |   `--IDENT -> tools
         |   |   `--IDENT -> checkstyle
         |   `--IDENT -> api
         `--SEMI -> ;

      • ARRAY_DECLARATOR

        public static final int ARRAY_DECLARATOR
        An array declaration.

        If the array declaration represents a type, then the type of the array elements is the first child. Multidimensional arrays may be regarded as arrays of arrays. In other words, the first child of the array declaration is another array declaration.

        For example:

           int[] x;
         

        parses as:

         VARIABLE_DEF -> VARIABLE_DEF
          |--MODIFIERS -> MODIFIERS
          |--TYPE -> TYPE
          |   |--LITERAL_INT -> int
          |   `--ARRAY_DECLARATOR -> [
          |       `--RBRACK -> ]
          |--IDENT -> x
          `--SEMI -> ;
         

        The array declaration may also represent an inline array definition. In this case, the first child will be either an expression specifying the length of the array or an array initialization block.

        Java Language Specification §10, TYPE, ARRAY_INIT, Constant Field Values
      • EXTENDS_CLAUSE

        public static final int EXTENDS_CLAUSE
        An extends clause. This appears as part of class and interface definitions. This element appears even if the extends keyword is not explicitly used. The child is an optional identifier.

        For example:

         public class Test extends ArrayList {
         }
         

        parses as:

         CLASS_DEF -> CLASS_DEF
         |--MODIFIERS -> MODIFIERS
         |   `--LITERAL_PUBLIC -> public
         |--LITERAL_CLASS -> class
         |--IDENT -> Test
         |--EXTENDS_CLAUSE -> extends
         |   `--IDENT -> ArrayList
         `--OBJBLOCK -> OBJBLOCK
             |--LCURLY -> {
             `--RCURLY -> }

        IDENT, DOT, CLASS_DEF, INTERFACE_DEF, FullIdent, Constant Field Values
      • IMPLEMENTS_CLAUSE

        public static final int IMPLEMENTS_CLAUSE
        An implements clause. This always appears in a class or enum declaration, even if there are no implemented interfaces. The children are a comma separated list of zero or more identifiers.

        For example:

         public class MyClass implements Collection {
        
         }
         

        parses as:

         CLASS_DEF -> CLASS_DEF
         |--MODIFIERS -> MODIFIERS
         |   `--LITERAL_PUBLIC -> public
         |--LITERAL_CLASS -> class
         |--IDENT -> MyClass
         |--IMPLEMENTS_CLAUSE -> implements
         |   `--IDENT -> Collection
         `--OBJBLOCK -> OBJBLOCK
             |--LCURLY -> {
             `--RCURLY -> }
         
        See Also:
        IDENT, DOT, COMMA, CLASS_DEF, ENUM_DEF, Constant Field Values
      • PARAMETERS

        public static final int PARAMETERS
        A list of parameters to a method or constructor. The children are zero or more parameter declarations separated by commas.

        For example

         int start, int end
         

        parses as:

         +--PARAMETERS
             |
             +--PARAMETER_DEF
                 |
                 +--MODIFIERS

                     |
                     +--LITERAL_INT (int)
                 +--IDENT (start)
             +--COMMA (,)
             +--PARAMETER_DEF
                 |

      • PARAMETER_DEF

        public static final int PARAMETER_DEF
        A parameter declaration. The last parameter in a list of parameters may be variable length (indicated by the ELLIPSIS child node immediately after the TYPE child).

        For example

              void foo(int firstParameter, int... secondParameter) {}

      • LITERAL_INSTANCEOF

        public static final int LITERAL_INSTANCEOF
        The instanceof operator. The first child is an object reference or something that evaluates to an object reference. The second child is a reference type or pattern.

        For example:

         boolean isBuilderPatternWithPattern =
                 text instanceof StringBuilder s; // type pattern, no `PATTERN_DEF`
