Examples of java.nio.IntBuffer

java.nio.IntBuffer
A buffer of ints.
A int buffer can be created in either of the following ways:
- {@link #allocate(int) Allocate} a new int array and create a bufferbased on it;
- {@link #wrap(int[]) Wrap} an existing int array to create a new buffer;
- Use {@link java.nio.ByteBuffer#asIntBuffer() ByteBuffer.asIntBuffer} tocreate a int buffer based on a byte buffer.

            assertEquals("Bad value at index " + i, MAGIC, buf.get(i));
        }

        IntBuffer buf  = IntBuffer.allocate(1024);
        final int MAGIC = 0xABEDCF23;
