Member Function Documentation

◆ internalParseHeader()

void TagParser::OggStream::internalParseHeader ( Diagnostics diag,
AbortableProgressFeedback progress 
)
overrideprotectedvirtual

This method is internally called to parse header information.

It needs to be implemented when subclassing this class.

Exceptions
Throwsstd::ios_base::failure when an IO error occurs.
ThrowsTagParser::Failure or a derived exception when a parsing error occurs.

Implements TagParser::AbstractTrack.

inline

Definition at line 34 of file oggstream.h.

◆ type()

TrackType TagParser::OggStream::type ( ) const
inlineoverridevirtual

Returns the type of the track if known; otherwise returns TrackType::Unspecified.
