public abstract class SFMLNativeObject
extends Object

Abstract base class for classes bound to SFML C++ objects.

This class serves as a communication interface between native SFML objects and their Java representations by linking the Java object to the object's native pointer.

There should be no reason whatsoever to use this class outside of JSFML itself.

Constructor Detail

SFMLNativeObject

protected SFMLNativeObject()

Constructs a JSFML native object by invoking the nativeCreate() method and retrieving a pointer to the SFML object in the JVM heap.

SFMLNativeObject

@Deprecated
protected SFMLNativeObject(long wrap)

Deprecated. Use of this constructor may cause undefined behaviour and is not supported.

Wraps an JSFML native object around an already existing native SFML object.

Parameters:

wrap - the pointer to the native SFML object in the JNI heap.

Method Detail

nativeCreate

@Deprecated
protected abstract long nativeCreate()

Deprecated. Use of this method may cause undefined behaviour and is not supported.

Creates a new native SFML object of the represented SFML class in the JVM memory heap.

Returns:

the pointer to the newly created native SFML object.

nativeSetExPtr

@Deprecated
protected abstract void nativeSetExPtr()

Deprecated. Use of this method may cause undefined behaviour and is not supported.

This method is expected to fill the extra pointers array, if any.

It is called after the object has been created or wrapped around an already existing pointer.

nativeDelete

@Deprecated
protected abstract void nativeDelete()

Deprecated. Use of this method may cause undefined behaviour and is not supported.

Deletes the underlying SFML object.

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
