Functions

func Init

func Init(env *jni.Env) error

Init resolves all JNI class and method references for this package. It is safe to call multiple times (uses sync.Once internally). Exported for E2E testing on Android.

Types

type Context

type Context struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

Context wraps android.media.effect.EffectContext.

func (*Context) CreateWithCurrentGlContext

func (m *Context) CreateWithCurrentGlContext() (*jni.Object, error)

CreateWithCurrentGlContext calls android.media.effect.EffectContext.createWithCurrentGlContext.

func (*Context) GetFactory

func (m *Context) GetFactory() (*jni.Object, error)

GetFactory calls android.media.effect.EffectContext.getFactory.

func (*Context) Release

func (m *Context) Release() error

Release calls android.media.effect.EffectContext.release.

func (*Context) ToString

func (m *Context) ToString() (string, error)

ToString calls android.media.effect.EffectContext.toString.

type Effect

type Effect struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

Effect wraps android.media.effect.Effect.

func (*Effect) Apply

func (m *Effect) Apply(
	arg0 int32,
	arg1 int32,
	arg2 int32,
	arg3 int32,
) error

Apply calls android.media.effect.Effect.apply.

func (*Effect) GetName

func (m *Effect) GetName() (string, error)

GetName calls android.media.effect.Effect.getName.

func (*Effect) Release

func (m *Effect) Release() error

Release calls android.media.effect.Effect.release.

func (*Effect) SetParameter

func (m *Effect) SetParameter(arg0 string, arg1 *jni.Object) error

SetParameter calls android.media.effect.Effect.setParameter.

func (*Effect) SetUpdateListener

func (m *Effect) SetUpdateListener(arg0 *jni.Object) error

SetUpdateListener calls android.media.effect.Effect.setUpdateListener.

func (*Effect) ToString

func (m *Effect) ToString() (string, error)

ToString calls android.media.effect.Effect.toString.

type Factory

type Factory struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

Factory wraps android.media.effect.EffectFactory.

func (*Factory) CreateEffect

func (m *Factory) CreateEffect(arg0 string) (*jni.Object, error)

CreateEffect calls android.media.effect.EffectFactory.createEffect.

func (*Factory) IsEffectSupported

func (m *Factory) IsEffectSupported(arg0 string) (bool, error)

IsEffectSupported calls android.media.effect.EffectFactory.isEffectSupported.

func (*Factory) ToString

func (m *Factory) ToString() (string, error)

ToString calls android.media.effect.EffectFactory.toString.

type UpdateListener

type UpdateListener struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

UpdateListener wraps android.media.effect.EffectUpdateListener.

func (*UpdateListener) OnEffectUpdated

func (m *UpdateListener) OnEffectUpdated(arg0 *jni.Object, arg1 *jni.Object) error

OnEffectUpdated calls android.media.effect.EffectUpdateListener.onEffectUpdated.

func (*UpdateListener) ToString

func (m *UpdateListener) ToString() (string, error)

ToString calls android.media.effect.EffectUpdateListener.toString.
