public class Pointer extends Object
An abstraction for a native pointer data type. A Pointer instance represents, on the Java side, a native pointer. The native pointer could be any type of native pointer. Methods such as `write`, `read`, `getXXX`, and `setXXX`, provide means to access memory underlying the native pointer.

While a constructor exists to create a Pointer from an integer value, it's not generally a good idea to be creating pointers that way.

      `value` - `short` value to set

  - ### setChar

    public void setChar(long offset, char value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((wchar_t *)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `char` value to set

  - ### setInt

    public void setInt(long offset, int value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((jint *)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `int` value to set

  - ### setLong

    public void setLong(long offset, long value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((jlong *)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `long` value to set

  - ### setNativeLong

    public void setNativeLong(long offset, NativeLong value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((long *)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `long` value to set

  - ### setFloat

    public void setFloat(long offset, float value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((jfloat *)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `float` value to set

  - ### setDouble

    public void setDouble(long offset, double value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((jdouble *)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `double` value to set

  - ### setPointer

    public void setPointer(long offset, Pointer value)
    Set `value` at location being pointed to. This is equivalent to the expression `*((void **)((char *)Pointer + offset)) = value`.
    Parameters:
      `offset` - byte offset from pointer at which `value` must be set
      `value` - `Pointer` holding the actual pointer value to set, which may be `null` to indicate a `NULL` pointer.

  - ### setWideString

    public void setWideString(long offset, String value)
    Copy string `value` to the location being pointed to as a wide string (`wchar_t*`).
    Parameters:
      `offset` - byte offset from pointer at which characters in `value` must be set
      `value` - `java.lang.String` value to set

  - ### setString

    public void setString(long offset, WString value)
    Copy string `value` to the location being pointed to as a wide string (`wchar_t*`).
    Parameters:
      `offset` - byte offset from pointer at which characters in `value` must be set
      `value` - `WString` value to set

  - ### setString

    public void setString(long offset, String value)
    Copy bytes out of string `value` to the location being pointed to, using the encoding indicated by `Native.getDefaultStringEncoding()`.
    Parameters:
      `offset` - byte offset from pointer at which characters in `value` must be set
      `value` - `java.lang.String` value to set

  - ### setString

    public void setString(long offset, String value, String encoding)
    Copy string `value` to the location being pointed to, using the requested encoding.
    Parameters:
      `offset` - byte offset from pointer at which characters in `value` must be set
      `value` - `java.lang.String` value to set
      `encoding` - desired encoding

  - ### dump

    public String dump(long offset, int size)
    Dump memory for debugging purposes.

  - ### toString

    public String toString()
    Overrides:
      `toString` in class `Object`

  - ### nativeValue

    public static long nativeValue(Pointer p)
    Read the native peer value. Use with caution.

  - ### nativeValue

    public static void nativeValue(Pointer p, long value)
