static bool Equals(float const&, float const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
static bool Equals(double const&, double const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
virtual bool FastCast(const Details::FastRttiBase&, void **) constFor internal purposes only.
static System::SharedPtr<PresentationFactory> get_Instance()Presentation factory static instance. Read-only PresentationFactory.
Detail::SmartPtrCounter * GetCounter()Gets reference counter data structure associated with the object.
virtual int32_t GetHashCode() constAnalog of C# Object.GetHashCode() method. Enables hashing of custom objects.
System::SharedPtr<IPresentationInfo> GetPresentationInfo(System::String) overrideCreates new PresentationInfo object from file and binds presentation to it.
System::SharedPtr<IPresentationInfo> GetPresentationInfo(System::SharedPtr<System::IO::Stream>) overrideCreates new PresentationInfo object from stream and binds presentation to it. Gets info about presentation in specified stream.
System::SharedPtr<IPresentationText> GetPresentationText(System::String, TextExtractionArrangingMode) overrideRetrieves the raw text from the slides
System::SharedPtr<IPresentationText> GetPresentationText(System::SharedPtr<System::IO::Stream>, TextExtractionArrangingMode) overrideRetrieves the raw text from the slides
System::SharedPtr<IPresentationText> GetPresentationText(System::SharedPtr<System::IO::Stream>, TextExtractionArrangingMode, System::SharedPtr<ILoadOptions>) overrideRetrieves the raw text from the slides
virtual const TypeInfo& GetType() constGets actual type of object. Analog of C# System.Object.GetType() call.
virtual bool Is(const TypeInfo&) constCheck if object represents an instance of type described by targetType. Analog of C# ‘is’ operator.
void Lock()Implements C# lock() statement locking. Call directly or use LockContext sentry object.
virtual ptr MemberwiseClone() constAnalog of C# Object.MemberwiseClone() method. Enables cloning custom types.
Object()Creates object. Initializes all internal data structures.
Object(Object const&)Copy constructor. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
Object& operator=(Object const&)Assignment operator. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
System::SharedPtr<IPresentation> ReadPresentation(System::ArrayPtr<uint8_t>) overrideReads an existing presentation from array
System::SharedPtr<IPresentation> ReadPresentation(System::ArrayPtr<uint8_t>, System::SharedPtr<ILoadOptions>) overrideReads an existing presentation from array with additional load options
System::SharedPtr<IPresentation> ReadPresentation(System::SharedPtr<System::IO::Stream>) overrideReads an existing presentation from stream
System::SharedPtr<IPresentation> ReadPresentation(System::SharedPtr<System::IO::Stream>, System::SharedPtr<ILoadOptions>) overrideReads an existing presentation from stream with additional load options
System::SharedPtr<IPresentation> ReadPresentation(System::String) overrideReads an existing presentation from file
System::SharedPtr<IPresentation> ReadPresentation(System::String, System::SharedPtr<ILoadOptions>) overrideReads an existing presentation from stream with additional load options
static bool ReferenceEquals(ptr const&, ptr const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, T const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, std::nullptr_t)Reference-compares value type object with nullptr.
bool ReferenceEquals(String const&, std::nullptr_t)Specialization of Object::ReferenceEquals for case of string and nullptr.
bool ReferenceEquals(String const&, String const&)Specialization of Object::ReferenceEquals for case of strings.
int RemovedSharedRefs(int)Decreases shared reference count by specified value.
virtual void SetTemplateWeakPtr(uint32_t)Set n’th template argument a weak pointer (rather than shared). Allows switching pointers in containers to weak mode.
int SharedCount() constGets current value of shared reference counter.
Object * SharedRefAdded()Increments shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
int SharedRefRemovedSafe()Decrements and returns shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual String ToString() constAnalog of C# Object.ToString() method. Enables converting custom objects to string.
static const TypeInfo& Type()Implements C# typeof(System.Object) construct.
void Unlock()Implements C# lock() statement unlocking. Call directly or use LockContext sentry object.
Detail::SmartPtrCounter * WeakRefAdded()Increments weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
void WeakRefRemoved()Decrements weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual ~Object()Destroys object. Frees all internal data structures.

Remarks

The following example shows how to checking a Presentation Format.

System::SharedPtr<IPresentationInfo> info = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.pptx");
System::Console::WriteLine(System::ExplicitCast<System::Object>(info->get_LoadFormat())); // PPTX
System::SharedPtr<IPresentationInfo> info2 = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.ppt");
System::Console::WriteLine(System::ExplicitCast<System::Object>(info2->get_LoadFormat())); // PPT
System::SharedPtr<IPresentationInfo> info3 = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.odp");
System::Console::WriteLine(System::ExplicitCast<System::Object>(info3->get_LoadFormat())); // ODP

The following example shows how to getting the properties of a Presentation.

System::SharedPtr<IPresentationInfo> info = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.pptx");
System::SharedPtr<IDocumentProperties> props = info->ReadDocumentProperties();
System::Console::WriteLine(System::ExplicitCast<System::Object>(props->get_CreatedTime()));
System::Console::WriteLine(props->get_Subject());
System::Console::WriteLine(props->get_Title());

The following example shows how to updating the properties of a Presentation.

System::SharedPtr<IPresentationInfo> info = PresentationFactory::get_Instance()->GetPresentationInfo(u"pres.pptx");
System::SharedPtr<IDocumentProperties> props = info->ReadDocumentProperties();
props->set_Title(u"My title");
info->UpdateDocumentProperties(props);
