This is a simple Java library for handling MessagePack data. It doesn't do any object mapping, but maps to special
|
||||||
|
objects representing MessagePack types. To build, use command `./gradlew build`.
|
||||||
|
|
||||||
|
For most cases you might be better off using `org.msgpack:msgpack`, but I found that I needed something that generically
|
||||||
|
represents the internal structure of the data.
|
||||||
|
|
||||||
|
msgpack uses Semantic Versioning, meaning as long as the major version doesn't change, nothing should break if you
|
||||||
|
update. Be aware though that this doesn't necessarily applies for SNAPSHOT builds and the development branch.

### Limitations
|
||||||
|
|
||||||
|
* There is no fallback to BigInteger for large integer type numbers, so there might be an integer overflow when reading
|
||||||
|
too large numbers
|
||||||
|
* `MPFloat` uses the data type you're using to decide on precision (float 32 or 64) - not the actual value. E.g. 0.5
|
||||||
|
could be saved perfectly as a float 42, but if you provide a double value, it will be stored as float 64, wasting
|
||||||
|
4 bytes.
|
||||||
|
|
||||||
|
### Setup
|
||||||
|
|
||||||
|
Add msgpack as Gradle dependency:
|
||||||
|
```Gradle
|
||||||
|
compile "ch.dissem.msgpack:msgpack:1.0.0"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Usage
|
||||||
|
|
||||||
|
#### Serialize Data
|
||||||
|
|
||||||
|
First, you'll need to create some msgpack objects to serialize:
|
||||||
|
```Java
|
||||||
|
MPMap<MPString, MPType<?>> object = new MPMap<>();
|
||||||
|
object.put(new MPString("compact"), new MPBoolean(true));
|
||||||
|
object.put(new MPString("schema"), new MPInteger(0));
|
||||||
|
```
|
||||||
|
or the shorthand version for simple types:
|
||||||
|
```Java
|
||||||
|
import static ch.dissem.msgpack.types.Utils.mp;
|
||||||
|
|
||||||
|
MPMap<MPString, MPType<?>> object = new MPMap<>();
|
||||||
|
object.put(mp("compact"), mp(true));
|
||||||
|
object.put(mp("schema"), mp(0));
|
||||||
|
```
|
||||||
|
then just use `pack(OutputStream)`:
|
||||||
|
```Java
|
||||||
|
OutputStream out = ...;
|
||||||
|
object.pack(out);
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
#### Deserialize Data
|
||||||
|
|
||||||
|
For deserializing data there is the reader object:
|
||||||
|
```Java
|
||||||
|
Reader reader = Reader.getInstance()
|
||||||
|
```
|
||||||
|
just use `reader.read(InputStream)`. Unfortunately you'll need to make sure you got what you expected, the following
|
||||||
|
example might result in `ClassCastException` at weird places:
|
||||||
|
```Java
|
||||||
|
InputStream in = ...;
|
||||||
|
MPType read = reader.read(in);
|
||||||
|
MPMap<MPString, MPString> map = (MPMap<MPString, MPString>) read;
|
||||||
|
String value = map.get(mp("key")).getValue();
|
||||||
|
```
