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
     |
     +--MODIFIERS
     +--TYPE
         |
         +--ARRAY_DECLARATOR ([)
             |
             +--LITERAL_INT (int)
     +--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.
See Also:

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

EXTENDS_CLAUSE
```

```
parses as:
```
 +--EXTENDS_CLAUSE
     |
     +--DOT (.)
         |
         +--DOT (.)
             |
             +--IDENT (java)
             +--IDENT (util)

TYPE_PARAMETERS

public static final int TYPE_PARAMETERS

For example:

     public class Blah<A, B>
     {
     }

parses as:

 +--CLASS_DEF ({)
     |

TYPE_PARAMETER
```
public static final int TYPE_PARAMETER
```
A type parameter to a class, interface or method definition. Children are the type name and an optional TYPE_UPPER_BOUNDS.
For example:
```
     A extends Collection
 
```
parses as:
```

A list of type arguments to a type reference or a method/ctor invocation. Children are GENERIC_START, at least one TYPE_ARGUMENT, zero or more of a COMMAs followed by a single TYPE_ARGUMENT, and a final GENERIC_END.

For example:

     public Collection<?> a;

TYPE_ARGUMENT
```
public static final int TYPE_ARGUMENT
```
