It's certainly *possible*. You certainly don't have to write a complete mapping in order to be able to use a subset of functionality.
If you're doing anything performance intensive, you should evaluate where you need speed versus where you need clarity and simplicity of operation.
I'd recommend starting with JNA and fall back to JNI only if you need to optimize or find something you *can't* do with JNA (although we try to make most things possible with JNA).

Hello,
I think about createing a directx binding for java. Do you think it is possible to use jna for this job or better use jni??
e.g
is it possible to map this code to java using jna: [code] typedef struct _D3DMATRIX { union { struct { float _11, _12, _13, _14; float _21, _22, _23, _24; float _31, _32, _33, _34; float _41, _42, _43, _44;
}; float m[4][4]; }; } D3DMATRIX; [/code]
or this one: [code] typedef interface IDirect3D9 IDirect3D9; [/code]
or this one: [code] #define INTERFACE IDirect3D9
DECLARE_INTERFACE_(IDirect3D9, IUnknown) { /*** IUnknown methods ***/ STDMETHOD(QueryInterface)(THIS_ REFIID riid, void** ppvObj) PURE; STDMETHOD_(ULONG,AddRef)(THIS) PURE; STDMETHOD_(ULONG,Release)(THIS) PURE;
/*** IDirect3D9 methods ***/ STDMETHOD(RegisterSoftwareDevice)(THIS_ void* pInitializeFunction) PURE; STDMETHOD_(UINT, GetAdapterCount)(THIS) PURE; STDMETHOD(GetAdapterIdentifier)(THIS_ UINT Adapter,DWORD Flags,D3DADAPTER_IDENTIFIER9* pIdentifier) PURE; STDMETHOD_(UINT, GetAdapterModeCount)(THIS_ UINT Adapter,D3DFORMAT Format) PURE; STDMETHOD(EnumAdapterModes)(THIS_ UINT Adapter,D3DFORMAT Format,UINT Mode,D3DDISPLAYMODE* pMode) PURE; STDMETHOD(GetAdapterDisplayMode)(THIS_ UINT Adapter,D3DDISPLAYMODE* pMode) PURE; STDMETHOD(CheckDeviceType)(THIS_ UINT Adapter,D3DDEVTYPE DevType,D3DFORMAT AdapterFormat,D3DFORMAT BackBufferFormat,BOOL bWindowed) PURE; STDMETHOD(CheckDeviceFormat)(THIS_ UINT Adapter,D3DDEVTYPE DeviceType,D3DFORMAT AdapterFormat,DWORD Usage,D3DRESOURCETYPE RType,D3DFORMAT CheckFormat) PURE; STDMETHOD(CheckDeviceMultiSampleType)(THIS_ UINT Adapter,D3DDEVTYPE DeviceType,D3DFORMAT SurfaceFormat,BOOL Windowed,D3DMULTISAMPLE_TYPE MultiSampleType,DWORD* pQualityLevels) PURE; STDMETHOD(CheckDepthStencilMatch)(THIS_ UINT Adapter,D3DDEVTYPE DeviceType,D3DFORMAT AdapterFormat,D3DFORMAT RenderTargetFormat,D3DFORMAT DepthStencilFormat) PURE; STDMETHOD(CheckDeviceFormatConversion)(THIS_ UINT Adapter,D3DDEVTYPE DeviceType,D3DFORMAT SourceFormat,D3DFORMAT TargetFormat) PURE; STDMETHOD(GetDeviceCaps)(THIS_ UINT Adapter,D3DDEVTYPE DeviceType,D3DCAPS9* pCaps) PURE; STDMETHOD_(HMONITOR, GetAdapterMonitor)(THIS_ UINT Adapter) PURE; STDMETHOD(CreateDevice)(THIS_ UINT Adapter,D3DDEVTYPE DeviceType,HWND hFocusWindow,DWORD BehaviorFlags,D3DPRESENT_PARAMETERS* pPresentationParameters,IDirect3DDevice9** ppReturnedDeviceInterface) PURE;
#ifdef D3D_DEBUG_INFO LPCWSTR Version; #endif }; [/code]
any suggestions are welcome.
