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.

Konstruktoren

Modifizierer	Konstruktor	Beschreibung
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.

Methodenübersicht

Modifizierer und Typ	Methode	Beschreibung
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()	Indicate the native type used by this converter.
void	setPointer(Pointer p)
Object	toNative()	Convert this object to its native type (a Pointer).

Konstruktordetails

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.

Methodendetails

nativeType

public Class<?> nativeType()

Beschreibung aus Schnittstelle kopiert: NativeMapped

Indicate the native type used by this converter.

Angegeben von:

nativeType in Schnittstelle NativeMapped

Gibt zurück:

Java class representation of the native type.

toNative

public Object toNative()

Convert this object to its native type (a Pointer).

Angegeben von:

toNative in Schnittstelle NativeMapped

Gibt zurück:

Java representation of the original Java object converted to a native type.

getPointer

public Pointer getPointer()

Returns the associated native Pointer.

Gibt zurück:

Native pointer representation for this object.

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.

Angegeben von:

fromNative in Schnittstelle NativeMapped

Parameter:

nativeValue - Java representation of the native type to be converted.

context - Context in which the conversion is taking place.

Gibt zurück:

Converted object.

hashCode

public int hashCode()

The hash code for a PointerType is the same as that for its pointer.

Setzt außer Kraft:

hashCode in Klasse Object

equals

public boolean equals(Object o)

Instances of PointerType with identical pointers compare equal by default.
