From 253067c782955380bbf66ac0475dc954375b1ff4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20Mr=C3=A1zek?= Date: Sat, 17 Aug 2013 13:40:51 +0200 Subject: Move all the things (YES. Move them.) Also, implemented some basic modlist logic, to be wired up. --- java/annotations.h | 252 ----------------------------------------------------- 1 file changed, 252 deletions(-) delete mode 100644 java/annotations.h (limited to 'java/annotations.h') diff --git a/java/annotations.h b/java/annotations.h deleted file mode 100644 index b115dc0b..00000000 --- a/java/annotations.h +++ /dev/null @@ -1,252 +0,0 @@ -#pragma once -#include "classfile.h" -#include -#include - -namespace java -{ - enum element_value_type : uint8_t - { - INVALID = 0, - STRING = 's', - ENUM_CONSTANT = 'e', - CLASS = 'c', - ANNOTATION = '@', - ARRAY = '[', // one array dimension - PRIMITIVE_INT = 'I', // integer - PRIMITIVE_BYTE = 'B', // signed byte - PRIMITIVE_CHAR = 'C', // Unicode character code point in the Basic Multilingual Plane, encoded with UTF-16 - PRIMITIVE_DOUBLE = 'D', // double-precision floating-point value - PRIMITIVE_FLOAT = 'F', // single-precision floating-point value - PRIMITIVE_LONG = 'J', // long integer - PRIMITIVE_SHORT = 'S', // signed short - PRIMITIVE_BOOLEAN = 'Z' // true or false - };
