Member Function Documentation

◆ GetObjectStoringLocation()

virtual LinkEmbedDecision Aspose::Slides::Export::ILinkEmbedController::GetObjectStoringLocation ( int32_t  id,
System::ArrayPtr< uint8_t >  entityData,
System::String  semanticName,
System::String  contentType,
System::String  recomendedExtension 
)
pure virtual

Determines where object should be stored. This method is called once for each object id. It is not guaranteed that there won't be two objects with same data, semanticName and contentType but with different id.

Parameters
idObject id. This id is saving operation-wide unique.
entityDataObject binary data. This parameter can be null, if object binary data is not generated yet.
semanticNameSome short text, describing meaning of object. Controller may use this as a part of external object name, but it is up to dispatcher to ensure that names will be unique and contain only allowed characters.
contentTypeMIME type of object.
recomendedExtensionFile name extension, recommended for this MIME type.
Returns
Decision

Implemented in Aspose::Slides::Export::VideoPlayerHtmlController.

◆ GetUrl()

virtual System::String Aspose::Slides::Export::ILinkEmbedController::GetUrl ( int32_t  id,
int32_t  referrer 
)
pure virtual

Returns an URL to an external object. This method always called if GetObjectStoringLocation returned LinkEmbedDecision::Link and may be called if GetObjectStoringLocation returned LinkEmbedDecision::Embed but embedding is impossible. Can be called multiple time for same object id.

Parameters
idObject id. This id is saving operation-wide unique.
referrerid of referrencing object or 0, if object is referrenced by the root document. May be used to generate relative link.
Returns
Url of external object or null if this object should be ignored.

Implemented in Aspose::Slides::Export::VideoPlayerHtmlController.

◆ SaveExternal()

virtual void Aspose::Slides::Export::ILinkEmbedController::SaveExternal ( int32_t  id,
System::ArrayPtr< uint8_t >  entityData 
)
pure virtual

Saves external object.

Parameters
idObject id. This id is saving operation-wide unique.
entityDataObject binary data. This parameter cannot be null.

Implemented in Aspose::Slides::Export::VideoPlayerHtmlController.
