Detailed Description
Content type detection chain element.
Detects and assigns content types to the provided data source using various detection strategies.
This class is a chain element that detects and assigns content types to data sources using the following detection methods:
- By file extension
- By file signature
- Image content detection
- ODF and OOXML format detection
- ASP content detection
- HTML content detection
- iWork content detection
- ODF Flat format detection
- Outlook format detection
- XLSB format detection

Constructor & Destructor Documentation
◆ detector()
|
inline |
Constructs a new detector with the given database of signatures.
The detector will use the provided database of signatures for content type detection. If no database is provided, it will be created and loaded.
- Parameters
-
signatures_db_to_use The database of signatures to be used for content type detection.

Member Function Documentation
◆ is_leaf()

Check if chain element is a leaf (last element which doesn't produce any messages). At this moment only exporters are leafs.
- Returns
- true if leaf
