ABSTRACT
public static final int ABSTRACT
The abstract
keyword.
ANNOTATION
public static final int ANNOTATION
An annotation of a package, type, field, parameter or variable.
An annotation may occur anywhere modifiers occur (it is a
type of modifier) and may also occur prior to a package definition.
The notable children are: The annotation name and either a single
default annotation value or a sequence of name value pairs.
Annotation values may also be annotations themselves.
For example:
@MyAnnotation(someField1 = "Hello",
someField2 = @SomeOtherAnnotation)
parses as:
+--ANNOTATION
|
+--AT (@)
+--IDENT (MyAnnotation)
+--LPAREN (()
+--ANNOTATION_MEMBER_VALUE_PAIR
|
+--IDENT (someField1)
+--ASSIGN (=)
+--ANNOTATION
|
+--AT (@)
+--IDENT (SomeOtherAnnotation)
+--ANNOTATION_MEMBER_VALUE_PAIR
|
+--IDENT (someField2)
+--ASSIGN (=)
+--STRING_LITERAL ("Hello")
+--RPAREN ())
ANNOTATIONS
public static final int ANNOTATIONS
A collection of annotations on a package or enum constant.
A collections of annotations will only occur on these nodes
as all other nodes that may be qualified with an annotation can
be qualified with any other modifier and hence these annotations
would be contained in a
MODIFIERS
node.
For example:
@MyAnnotation package blah;
parses as:
+--PACKAGE_DEF (package)
|
+--ANNOTATIONS
|
+--ANNOTATION
|
+--AT (@)
+--IDENT (MyAnnotation)
+--IDENT (blah)
+--SEMI (;)
ANNOTATION_ARRAY_INIT
public static final int ANNOTATION_ARRAY_INIT
An annotation array member initialisation.
Initializers can not be nested.
Am initializer may be present as a default to a annotation
member, as the single default value to an annotation
(e.g. @Annotation({1,2})) or as the value of an annotation
member value pair.
For example:
{ 1, 2 }
parses as:
+--ANNOTATION_ARRAY_INIT ({)
|
+--NUM_INT (1)
+--COMMA (,)
+--NUM_INT (2)
+--RCURLY (})
ANNOTATION_DEF
public static final int ANNOTATION_DEF
An annotation declaration. The notable children are the name of the
annotation type, annotation field declarations and (constant) fields.
For example:
public @interface MyAnnotation
{
int someValue();
}
parses as:
+--ANNOTATION_DEF
|
+--MODIFIERS
|
+--LITERAL_PUBLIC (public)
+--AT (@)
+--LITERAL_INTERFACE (interface)
+--IDENT (MyAnnotation)
+--OBJBLOCK

+--RCURLY (})
ANNOTATION_FIELD_DEF
public static final int ANNOTATION_FIELD_DEF

field type, field name and an optional default value (a conditional
compile-time constant expression). Default values may also by
annotations.
For example:
String someField() default "Hello world";
parses as:
+--ANNOTATION_FIELD_DEF
|
+--MODIFIERS
+--TYPE
|
+--IDENT (String)
+--IDENT (someField)

ANNOTATION_MEMBER_VALUE_PAIR
public static final int ANNOTATION_MEMBER_VALUE_PAIR
An initialisation of an annotation member with a value.
Its children are the name of the member, the assignment literal
and the (compile-time constant conditional expression) value.
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)

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.
ARRAY_INIT
public static final int ARRAY_INIT

declaration or inline with
new
.
For example:
int[] y =
{
1,
2,
};
parses as:
+--VARIABLE_DEF
|
+--MODIFIERS
+--TYPE
|
+--ARRAY_DECLARATOR ([)
|
+--LITERAL_INT (int)
+--IDENT (y)
