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

Usage

From source file:Main.java

public static final int compareTo(ByteBuffer bb1, ByteBuffer bb2) {
    return compareTo(bb1.array(), 0, bb1.limit(), bb2.array(), 0, bb2.limit());
}

From source file:Main.java

public static Object getObject(ByteBuffer byteBuffer) throws ClassNotFoundException, IOException {
    InputStream input = new ByteArrayInputStream(byteBuffer.array());
    ObjectInputStream oi = new ObjectInputStream(input);
    Object obj = oi.readObject();
    input.close();//from  w ww  . j  a  v  a  2s .c o m
    oi.close();
    byteBuffer.clear();
    return obj;
}

From source file:Main.java

public final static boolean equalsP(final ByteBuffer bb1, final ByteBuffer bb2) {
    final byte[] array1 = bb1.array();
    final byte[] array2 = bb2.array();
    final int offset1 = bb1.position();
    final int offset2 = bb2.position();
    final int end1 = bb1.limit();
    final int end2 = bb2.limit();
    return equals(array1, offset1, end1, array2, offset2, end2);
}

}

From source file:net.sf.jml.util.DigestUtils.java
