A buffer of ints.
A int buffer can be created in either of the following ways:
          
           Allocate
          
         
         a new int array and create a buffer
 based on it;
        
          
           Wrap
          
         
         an existing int array to create a new buffer;
        
          
           ByteBuffer.asIntBuffer
          
         
         to
 create a int buffer based on a byte buffer.

Returns the array that backs this buffer (optional operation). The returned value is the actual array, not a copy, so modifications to the array write through to the buffer.
Subclasses should override this method with a covariant return type to provide the exact type of the array.

          hasArray
         
         to ensure this method won't throw.

          array

 element of the buffer (optional operation). The backing array (if there is one)
 is not necessarily the same size as the buffer, and position 0 in the buffer is
 not necessarily the 0th element in the array. Use

Returns a read-only buffer that shares its content with this buffer.
The returned buffer is guaranteed to be a new instance, even this buffer is read-only itself. The new buffer's position, limit, capacity and mark are the same as this buffer's.
The new buffer shares its content with this buffer, which means this buffer's change of content will be visible to the new buffer. The two buffer's position, limit and mark are independent.
Compacts this int buffer.
         The remaining ints will be moved to the head of the buffer, starting from
 position zero. Then the position is set to
         
          remaining()
         
         ; the
 limit is set to capacity; the mark is cleared.

Returns a duplicated buffer that shares its content with this buffer.
The duplicated buffer's position, limit, capacity and mark are the same as this buffer. The duplicated buffer's read-only property and byte order are the same as this buffer's.
The new buffer shares its content with this buffer, which means either buffer's change of content will be visible to the other. The two buffers' position, limit and mark are independent.
Checks whether this int buffer is equal to another object.
         If

Calculates this buffer's hash code from the remaining chars. The position, limit, capacity and mark don't affect the hash code.
Indicates whether this buffer is direct. A direct buffer will try its best to take advantage of native memory APIs and it may not stay in the Java heap, so it is not affected by garbage collection.
An int buffer is direct if it is based on a byte buffer and the byte buffer is direct.

         The new buffer's position will be
         
          start
