    Throws:
    
    java.nio.InvalidMarkException - If the mark has not been set
  - clear
```
public PointerBuffer clear()
```
    Clears this buffer. The position is set to zero, the limit is set to the capacity, and the mark is discarded.
    Invoke this method before using a sequence of channel-read or put operations to fill this buffer. For example:
    
    buf.clear(); // Prepare buffer for reading in.read(buf); // Read data
    
    This method does not actually erase the data in the buffer, but it is named as if it did because it will most often be used in situations in which that might as well be the case.
    Returns:
    
    This buffer
  - flip
```
public PointerBuffer flip()
```
    Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.
    After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example:
    
    buf.put(magic); // Prepend header in.read(buf); // Read data into rest of buffer buf.flip(); // Flip buffer out.write(buf); // Write header + data to channel
    
    This method is often used in conjunction with the PointerBuffer.compact() method when transferring data from one place to another.
    Returns:
    
    This buffer
  - rewind
```
public PointerBuffer rewind()
```
    Rewinds this buffer. The position is set to zero and the mark is discarded.
    Invoke this method before a sequence of channel-write or get operations, assuming that the limit has already been set appropriately. For example:
    
    out.write(buf); // Write remaining data buf.rewind(); // Rewind buffer buf.get(array); // Copy data into array
    Returns:
    
    This buffer
  - remaining
```
public int remaining()
```
    Returns the number of elements between the current position and the limit.
    
    Returns:
    
    the number of elements remaining in this buffer
  - hasRemaining
```
public boolean hasRemaining()
```
    Tells whether there are any elements between the current position and the limit.
    
    Returns:
    
    true if, and only if, there is at least one element remaining in this buffer
  - slice
```
public abstract PointerBuffer slice()
```
    Creates a new pointer buffer whose content is a shared subsequence of this buffer's content.
    The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
    
    The new buffer's position will be zero, its capacity and its limit will be the number of pointers remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
    
    Returns:
    
    the new pointer buffer
  - duplicate
```
public abstract PointerBuffer duplicate()
```
    Creates a new pointer buffer that shares this buffer's content.
    The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
    The new buffer's capacity, limit and position will be identical to those of this buffer.
    
    Returns:
    
    the new pointer buffer
  - get
```

    Relative bulk get method.
    This method transfers pointers from this buffer into the specified destination array. An invocation of this method of the form src.get(a) behaves in exactly the same way as the invocation
    src.get(a, 0, a.length)
    Returns:
    
    This buffer
    
    Throws:
    
    java.nio.BufferUnderflowException - If there are fewer than length pointers remaining in this buffer
  - get
```
public PointerBuffer get(long[] dst,
                         int offset,
                         int length)
```
    Relative bulk get method.
    This method transfers pointers from this buffer into the specified destination array. If there are fewer pointers remaining in the buffer than are required to satisfy the request, that is, if length > remaining(), then no pointers are transferred and a BufferUnderflowException is thrown.
    Otherwise, this method copies length pointers from this buffer into the specified array, starting at the current position of this buffer and at the specified offset in the array. The position of this buffer is then incremented by length.
    In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop
    
    for (int i = off; i < off + len; i++) dst[i] = src.get();
    
    except that it first checks that there are sufficient pointers in this buffer and it is potentially much more efficient.
    Parameters:
    
    dst - the array into which pointers are to be written
    
    offset - the offset within the array of the first pointer to be written; must be non-negative and no larger than dst.length
    
    length - the maximum number of pointers to be written to the specified array; must be non-negative and no larger than dst.length - offset
    
    Returns:
    
    This buffer
    
    Throws:
    
    java.nio.BufferUnderflowException - If there are fewer than length pointers remaining in this buffer
    
    java.lang.IndexOutOfBoundsException - If the preconditions on the offset and length parameters do not hold
  - put
```
public PointerBuffer put(PointerBuffer src)
```
    Relative bulk put method (optional operation).
    This method transfers the pointers remaining in the specified source buffer into this buffer. If there are more pointers remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no pointers are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies n = src.remaining() pointers from the specified buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.
    
    In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop
    
    while (src.hasRemaining()) dst.put(src.get());
    
    except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.
    Parameters:
    
    src - the source buffer from which pointers are to be read; must not be this buffer
    
    Returns:
    
    This buffer
    
    Throws:
    
    java.nio.BufferOverflowException - If there is insufficient space in this buffer for the remaining pointers in the source buffer
    
    java.lang.IllegalArgumentException - If the source buffer is this buffer
    
    java.nio.ReadOnlyBufferException - If this buffer is read-only
  - put
```
public PointerBuffer put(long[] src)
```
    Relative bulk put method (optional operation).
    This method transfers the entire content of the specified source pointer array into this buffer. An invocation of this method of the form dst.put(a) behaves in exactly the same way as the invocation
    
    dst.put(a, 0, a.length)
    Returns:
    
    This buffer
    
    Throws:
    
    java.nio.BufferOverflowException - If there is insufficient space in this buffer
    
    java.nio.ReadOnlyBufferException - If this buffer is read-only
  - put
```
public PointerBuffer put(long[] src,
                         int offset,
                         int length)
```
    Relative bulk put method (optional operation).
    This method transfers pointers into this buffer from the specified source array. If there are more pointers to be copied from the array than remain in this buffer, that is, if length > remaining(), then no pointers are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies length pointers from the specified array into this buffer, starting at the specified offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.
    
    In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop
    
    for (int i = off; i < off + len; i++) dst.put(a[i]);
    
    except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.
    Parameters:
    
    src - the array from which pointers are to be read
    
    offset - the offset within the array of the first pointer to be read; must be non-negative and no larger than array.length
    
    length - the number of pointers to be read from the specified array; must be non-negative and no larger than array.length - offset
    
    Returns:
    
    This buffer
    
    Throws:
    
    java.nio.BufferOverflowException - If there is insufficient space in this buffer
    
    java.lang.IndexOutOfBoundsException - If the preconditions on the offset and length parameters do not hold
    
    java.nio.ReadOnlyBufferException - If this buffer is read-only
  - compact
```
public PointerBuffer compact()
```
    Compacts this buffer (optional operation).
    The pointers between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the pointer at index p = position() is copied to index zero, the pointer at index p + 1 is copied to index one, and so forth until the pointer at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.
    The buffer's position is set to the number of pointers copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.
    
    Returns:
    
    This buffer
    
    Throws:
    
    java.nio.ReadOnlyBufferException - If this buffer is read-only
  - order
```
public java.nio.ByteOrder order()
```
    Retrieves this buffer's byte order.
    The byte order of a pointer buffer created by allocation or by wrapping an existing pointer array is the native order of the underlying hardware. The byte order of a pointer buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.
    
    Returns:
    
    This buffer's byte order
  - toString
```
public java.lang.String toString()
```
    Returns a string summarizing the state of this buffer.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    A summary string
  - hashCode
```
public int hashCode()
```
    Returns the current hash code of this buffer.
    The hash code of a pointer buffer depends only upon its remaining elements; that is, upon the elements from position() up to, and including, the element at limit() - 1.
    
    Because buffer hash codes are content-dependent, it is inadvisable to use buffers as keys in hash maps or similar data structures unless it is known that their contents will not change.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    the current hash code of this buffer
  - equals
```
public boolean equals(java.lang.Object ob)
```
    Tells whether or not this buffer is equal to another object.
    Two pointer buffers are equal if, and only if,
    
    They have the same element type,
    
    They have the same number of remaining elements, and
    
    The two sequences of remaining elements, considered independently of their starting positions, are pointwise equal.
    
    A pointer buffer is not equal to any other type of object.
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    ob - the object to which this buffer is to be compared
    
    Returns:
    
    true if, and only if, this buffer is equal to the given object
  - compareTo
```
public int compareTo(PointerBuffer that)
```
    Compares this buffer to another.
    Two pointer buffers are compared by comparing their sequences of remaining elements lexicographically, without regard to the starting position of each sequence within its corresponding buffer.
    
    A pointer buffer is not comparable to any other type of object.
    
    Specified by:
    
    compareTo in interface java.lang.Comparable<PointerBuffer>
    
    Returns:
    
    A negative integer, zero, or a positive integer as this buffer is less than, equal to, or greater than the specified buffer
