Detailed Description

Mix-in class representing info subobject in content JSON.

This is one of base classes for content types that deal with files or URLs. It stores file metadata attributes, such as size, MIME type etc. found in the content/info subobject of event JSON payloads. Actual content classes derive from this class and Base that provides a polymorphic interface to access data in the mix-in. FileInfo (as well as ImageInfo, that adds image size to the metadata) is NOT polymorphic and is used in a non-polymorphic way to store thumbnail metadata (in a separate instance), next to the metadata on the file itself.

If you need to make a new content (not info) class based on files/URLs take UrlBasedContent as the example, i.e.:

  1. Double-inherit from this class (or ImageInfo) and Base.
  2. Provide a constructor from QJsonObject that will pass the info subobject (not the whole content JSON) down to FileInfo/ImageInfo.
  3. Override fillJson() to customise the JSON export logic. Make sure to call toInfoJson() from it to produce the payload for the info subobject in the JSON payload.

Constructor & Destructor Documentation

◆ FileInfo() [1/4]

Quotient::EventContent::FileInfo::FileInfo ( )
default

◆ FileInfo() [2/4]

Quotient::EventContent::FileInfo::FileInfo ( const QFileInfo &  fi)
explicit

Construct from a QFileInfo object.

Parameters
fia QFileInfo object referring to an existing file

◆ FileInfo() [3/4]

Quotient::EventContent::FileInfo::FileInfo ( FileSourceInfo  sourceInfo,
qint64  payloadSize = -1,
const QMimeType &  mimeType = {},
QString  originalFilename = {} 
)
explicit

◆ FileInfo() [4/4]

Quotient::EventContent::FileInfo::FileInfo ( FileSourceInfo  sourceInfo,
const QJsonObject &  infoJson,
QString  originalFilename = {} 
)

Construct from a JSON info payload.

Make sure to pass the info subobject of content JSON, not the whole JSON content.

Member Function Documentation

◆ isValid()

bool Quotient::EventContent::FileInfo::isValid ( ) const

◆ mediaId()

QString Quotient::EventContent::FileInfo::mediaId ( ) const
inline

Extract media id from the URL.

This can be used, e.g., to construct a QML-facing image:// URI as follows:

"image://provider/" + info.mediaId()
