Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer buf = ByteBuffer.allocate(10);
}

From source file:Main.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.allocate(8);
    printBufferInfo(bb);// w  w w  .  ja v a2s  .  co m
    for (int i = 50; i < 58; i++) {
        bb.put((byte) i);
    }
    printBufferInfo(bb);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer buf = ByteBuffer.allocate(10);
    buf.putShort(0, (short) 123);
    buf.get(0); // 0
    buf.get(1); // 123
}

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.hasArray());
}

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.isDirect());
}

From source file:Main.java

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

From source file:Main.java

    int capacity = bbuf.capacity(); // 10
    System.out.println(capacity);
    bbuf.putShort(2, (short) 123);

    ByteBuffer bb = bbuf.duplicate();

    System.out.println(bb.equals(bb));
}

From source file:Main.java
