Returns the byte array which this buffer is based on, if there is one.

Usage

From source file:Main.java

public static byte[] intToByteArray(int value) {
    ByteBuffer buffer = ByteBuffer.allocate(Integer.SIZE / Byte.SIZE);
    buffer.order(ByteOrder.BIG_ENDIAN);
    buffer.putInt(value);/*  w w  w. ja  v  a 2s .co m*/
    return buffer.array();
}

From source file:Main.java

public static byte[] shortToByteArrayLE(short value) {
    ByteBuffer buffer = ByteBuffer.allocate(Short.SIZE / Byte.SIZE);
    buffer.order(ByteOrder.LITTLE_ENDIAN);
    buffer.putShort(value);//from   w ww. j a  v  a2s.c om
    return buffer.array();
}

From source file:Main.java

        final int len) {

    return len;
}
