Creates a new byte buffer by wrapping the given byte array.

Usage

From source file:com.sm.store.Utils.java

public static void addBlockLong(Value value, Value block) {
    ByteBuffer buf = ByteBuffer.wrap((byte[]) value.getData());
    //block value is integer
    long k = buf.getLong() + ByteBuffer.wrap((byte[]) block.getData()).getInt();
    byte[] data = putLong(k);
    value.setData(data);//from  w w w . jav  a 2s .c o  m
    value.setVersion(value.getVersion() + 1);
