PointerType (JNA API)

java.lang.Object
- com.sun.jna.PointerType

All Implemented Interfaces:

NativeMapped

Direct Known Subclasses:

ByReference, WinNT.HANDLE, X11.Display, X11.GC, X11.Screen, X11.Visual, X11.XImage
```
public abstract class PointerType
extends Object
implements NativeMapped
```
Type representing a type-safe native pointer. Derived classes may override the NativeMapped.fromNative(java.lang.Object, com.sun.jna.FromNativeContext) method, which should instantiate a new object (or look up an existing one) of the appropriate type.

Constructor Summary

Constructors
Modifier	Constructor and Description
`protected`	`PointerType()` The default constructor wraps a NULL pointer.
`protected`	`PointerType(Pointer p)` This constructor is typically used by `fromNative(java.lang.Object, com.sun.jna.FromNativeContext)` if generating a new object instance.

Method Summary

Methods
Modifier and Type	Method and Description
`boolean`	`equals(Object o)` Instances of `PointerType` with identical pointers compare equal by default.
`Object`	`fromNative(Object nativeValue, FromNativeContext context)` The default implementation simply creates a new instance of the class and assigns its pointer field.
`Pointer`	`getPointer()` Returns the associated native `Pointer`.
`int`	`hashCode()` The hash code for a `PointerType` is the same as that for its pointer.
`Class`	`nativeType()` All `PointerType` classes represent a native `Pointer`.
`void`	`setPointer(Pointer p)`
`Object`	`toNative()` Convert this object to its native type (a `Pointer`).
`String`	`toString()`

- Constructor Detail
  - PointerType
```
protected PointerType()
```
    The default constructor wraps a NULL pointer.
  - PointerType
```
protected PointerType(Pointer p)
```
    This constructor is typically used by fromNative(java.lang.Object, com.sun.jna.FromNativeContext) if generating a new object instance.
- Method Detail
  - nativeType
```
public Class nativeType()
```
    All PointerType classes represent a native Pointer.
    
    Specified by:
    
    nativeType in interface NativeMapped
  - toNative
```
public Object toNative()
```
    Convert this object to its native type (a Pointer).
    
    Specified by:
    
    toNative in interface NativeMapped
  - getPointer
```
public Pointer getPointer()
```
    Returns the associated native Pointer.
  - setPointer
```
public void setPointer(Pointer p)
```
  - fromNative
```
public Object fromNative(Object nativeValue,
                FromNativeContext context)
```
    The default implementation simply creates a new instance of the class and assigns its pointer field. Override if you need different behavior, such as ensuring a single PointerType instance for each unique Pointer value, or instantiating a different PointerType subclass.
    
    Specified by:
    
    fromNative in interface NativeMapped
  - hashCode
```
public int hashCode()
```
    The hash code for a PointerType is the same as that for its pointer.
    
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object o)
```
    Instances of PointerType with identical pointers compare equal by default.
    
    Overrides:
    
    equals in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
