# NBT Lib
![version: v1.1-RC](https://img.shields.io/badge/version-v1.1--RC-a0a.svg?style=flat)
![coverage: 93%](https://img.shields.io/badge/coverage-93%25-darkgreen.svg?style=flat)
![version: 2.0-SNAPSHOT](https://img.shields.io/badge/version-2.0--SNAPSHOT-a0a.svg?style=flat)
Библиотека для работы с NBT (Named Binary Tag).
Начиная с версии `1.1-RC` разделена на две составляющие: теги и кодеки. Последние занимаются (де)сериализацией тегов.
## Примеры работы с NBT
## Примеры работы
**Создание тега типа String:**
```java
TagString tagString = new TagString();
tagString.setValue("hello!");
```
или в одну строчку
```java
TagString tagString = new TagString("hello!");
StringTag tag = new StringTag("Hello World!");
```
**Создание тега типа Compound:**
```java
TagCompound tagCompound = new TagCompound();
tagCompound.getValue().add(new TagLong("Seed", 1234567890));
CompoundTag tag = new CompoundTag()
.append("Seed", new LongTag(1234567890));
```
## Сериализация NBT
Сериализация в бинарный формат Minecraft Vanilla выполняется библиотекой `nbt-vanilla-codec`.
## Сериализация
Пример сериализации тега типа String в файл
```java
NbtOutputStream nbtOutputStream = new NbtOutputStream(new FileOutputStream("somefile.bin"));
nbtOutputStream.writeTag(new TagString("hello!"));
nbtOutputStream.close();
try (NbtOutputStream nbtOutputStream = new NbtOutputStream(new FileOutputStream("somefile.bin"))) {
nbtOutputStream.writeTag(new StringTag("hello!"));
}
```
По такому же принципу происходит и десериализация
```java
NbtInputStream nbtInputStream = new NbtInputStream(new FileInputStream("somefile.bin"));
Tag tag = nbtInputStream.readTag();
nbtInputStream.close();
if (tag.getType() == TypeTag.STRING) {
TagString tagString = tag.asTagString();
}
```

## Gradle start up script for UN*X
##
#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.
