```
public abstract class Pointer
extends Object
```
A native memory address. This class provides operations on a native memory address. Most Pointerinstances will represent direct memory (that is, a fixed address in the process address space, directly accessible by native code), however, it is possible to wrap a java byte array in a Pointerinstance to pass to a native function as a memory address. See isDirect() for more information.

```
public static Pointer wrap(Runtime runtime,
                           long address)
```
    Wraps a native address in a Pointer instance.
    
    Parameters:
    
    runtime - the Runtime of the pointer.
    
    address - the address to wrap in a Pointer instance.
    
    Returns:
    
    a Pointer instance.
  - wrap
```
public static Pointer wrap(Runtime runtime,
                           long address,
                           long size)
```
    Wraps a native address in a Pointer instance.
    
    Parameters:
    
    runtime - the Runtime of the pointer.
    
    address - the address to wrap in a Pointer instance.
    
    size - the size of the native memory region.
    
    Returns:

  - wrap
```
public static Pointer wrap(Runtime runtime,
                           ByteBuffer buffer)
```
    Wraps an existing ByteBuffer in a Pointer implementation so it can be used as a parameter to native functions.
    Wrapping a ByteBuffer is only neccessary if the native function parameter was declared as a Pointer. The if the method will always be used with ByteBuffer parameters, then the parameter type can just be declared as ByteBuffer and the conversion will be performed automatically.
    
    Parameters:
    
    runtime - the Runtime the wrapped ByteBuffer will be used with.
    
    buffer - the ByteBuffer to wrap.
    
    Returns:
    
    a Pointer instance that will proxy all accesses to the ByteBuffer contents.
  - newIntPointer
```
public static Pointer newIntPointer(Runtime runtime,
                                    long address)
```
    Wraps an integer value in an opaque Pointer instance. This is a Pointer instance that throws errors when any of the memory access methods are used, but can be otherwise used interchangeably with a real Pointer.
    
    Parameters:
    
    runtime - the Runtime of the pointer.
    
    address - the address to wrap in a Pointer instance.
    
    Returns:
    
    a Pointer instance.
  - isDirect
```
public final boolean isDirect()
```
    Indicates whether or not this memory object represents a native memory address.
    Memory objects can be either direct (representing native memory), or non-direct (representing java heap memory).
    Non-direct memory objects can still be passed to native functions as pointer (void *, char *, etc) parameters, but the java memory will first be copied to a temporary native memory area. The temporary memory area will then be used as the parameter value for the call. If needed, the java memory will be automatically reloaded from the temporary native memory after the native function returns.
    Note: the transient nature of the temporary memory allocated for non-direct memory means native functions which store the address value passed to them will fail in unpredictable ways when using non-direct memory. You will need to explicitly allocate direct memory to use those types of functions.
    
    Returns:
    
    true if, and only if, this memory object represents a native address.
  - address
```
public final long address()
```
    Gets the native address of this memory object (optional operation).

    Returns:
    
    the Runtime instance of this Pointer.

```
public abstract long size()
```
