Examples of com.esotericsoftware.kryo.io.Input

com.esotericsoftware.kryo.io.Input
An InputStream that reads data from a byte array and optionally fills the byte array from another InputStream as needed. Utility methods are provided for efficiently reading primitive types and strings.
The byte[] buffer may be modified and then returned to its original state during some read operations, so the same byte[] should not be used concurrently in separate threads. @author Nathan Sweet
