vario
Java 8 library for reading/writing variable-length primitives (VarInt, VarUInt, VarFloat, VarDouble)
## Quick Start
### Declaration
#### Gradle (Kotlin)
```kotlin
dependencies {
implementation("io.github.wasabithumb:vario:0.1.0")
}
```
#### Gradle (Groovy)
```groovy
dependencies {
implementation 'io.github.wasabithumb:vario:0.1.0'
}
```
#### Maven
```xml
io.github.wasabithumb
vario
0.1.0
compile
```
### Basic Usage
```java
VarDataOutputStream vdos = new VarDataOutputStream(os);
// Signed 32-bit integers
vdos.writeVarInt32(100);
vdos.writeVarInt32(-100);
// Unsigned 32-bit integers
vdos.writeVarUInt32(50);
vdos.writeVarUInt32(200);
// Signed 64-bit integers
vdos.writeVarInt64(Long.MIN_VALUE);
vdos.writeVarInt64(Long.MAX_VALUE);
// Unsigned 64-bit integers
vdos.writeVarUInt64(0x400000000L);
vdos.writeVarUInt64(0x800000000L);
// 32-bit floats
vdos.writeFloat(0.75f);
vdos.writeFloat(Float.NaN);
// 64-bit floats
vdos.writeDouble(1.25d);
vdos.writeDouble(Double.NaN);
```
