## Maven Dependency
Add this to the dependencies section of your pom.xml file:
```xml
<dependency>
<groupId>co.nstant.in</groupId>
<artifactId>cbor</artifactId>
<version>0.8</version>
</dependency>
```
## Usage
### Encoding Example
```java
ByteArrayOutputStream baos = new ByteArrayOutputStream();
new CborEncoder(baos).encode(new CborBuilder()
.add("text") // add string
.add(1234) // add integer
.add(new byte[] { 0x10 }) // add byte array
.addArray() // add array
.add(1)
.add("text")
.end()
.build());
byte[] encodedBytes = baos.toByteArray();
```
### Decoding Example
```java
ByteArrayInputStream bais = new ByteArrayInputStream(encodedBytes);
List<DataItem> dataItems = new CborDecoder(bais).decode();
for(DataItem dataItem : dataItems) {
// process data item
}
```
### Streaming Decoding Example
```java
ByteArrayInputStream bais = new ByteArrayInputStream(encodedBytes);
new CborDecoder(bais).decode(new DataItemListener() {
@Override
public void onDataItem(DataItem dataItem) {
// process data item
}
});
```
