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

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer bbuf = ByteBuffer.allocate(10);
    int capacity = bbuf.capacity(); // 10
    System.out.println(capacity);
    bbuf.putShort(2, (short) 123);

    System.out.println(bbuf.arrayOffset());
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer bbuf = ByteBuffer.allocate(10);
    int capacity = bbuf.capacity(); // 10
    System.out.println(capacity);
    bbuf.putShort(2, (short) 123);
    System.out.println(Arrays.toString(bbuf.array()));

    System.out.println(bbuf.arrayOffset());
}

From source file:Main.java

public static boolean wrapsFullArray(ByteBuffer byteBuffer) {
    return byteBuffer.hasArray() && byteBuffer.position() == 0 && byteBuffer.arrayOffset() == 0
            && byteBuffer.remaining() == byteBuffer.capacity();
}

From source file:Main.java

public static void toString(ByteBuffer bb, StringBuilder sb) {
    byte[] buf = bb.array();

    int arrayOffset = bb.arrayOffset();
    int offset = arrayOffset + bb.position();
    int origLimit = arrayOffset + bb.limit();
    int limit = (origLimit - offset > 128) ? offset + 128 : origLimit;

    for (int i = offset; i < limit; i++) {
        if (i > offset) {
            sb.append(" ");
        }/*from ww w.  ja v  a2 s .c o m*/
        sb.append(paddedByteString(buf[i]));
    }
    if (origLimit != limit) {
        sb.append("...");
    }
}
