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.
The constructors are intentionally package-private, since it's not generally a good idea to be creating C pointers de novo.

    Returns an array of String based on a native array of char* or wchar_t* based on the wide parameter, using the given array length.
  - setValue
```
void setValue(long offset,
            Object value,

```
  - setMemory
```
public void setMemory(long offset,
             long length,
             byte value)
```
    Write value to the requested bank of memory.
    
    Parameters:
    offset - byte offset from pointer to start
    length - number of bytes to write
    value - value to be written
  - setByte
```
public void setByte(long offset,
           byte value)
```
    Set value at location being pointed to. This is equivalent to the expression *((jbyte *)((char *)Pointer + offset)) = value.
    
    Parameters:
    offset - byte offset from pointer at which value must be set
    value - byte value to set
  - setShort
```
public void setShort(long offset,
            short value)
```
    Set value at location being pointed to. This is equivalent to the expression *((jshort *)((char *)Pointer + offset)) = value.
    
    Parameters:
    offset - byte offset from pointer at which value must be set
    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.
  - setString
```
public void setString(long offset,
             String value,
             boolean wide)
```
    Copy string value to the location being pointed to. Copy each element in value, converted to native encoding, at an offsetfrom the location pointed to by this pointer.
    
    Parameters:
    offset - byte offset from pointer at which characters in value must be set
    value - java.lang.String value to set
    wide - whether to write the native string as an array of wchar_t. If false, writes as a NUL-terminated array of char using the default platform encoding.
  - setString
```
public void setString(long offset,
             String value)
```
    Copy string value to the location being pointed to. Copy each element in value, converted to native encoding, at an offsetfrom the location pointed to by this pointer. Uses the value of the system property jna.encoding, if set, to determine the appropriate native charset in which to encode the value. If the property is not set, uses the default platform encoding.
    
    Parameters:
    offset - byte offset from pointer at which characters in value must be set
    value - java.lang.String value to set
  - 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)
```
    Set the native peer value. Use with caution.
