Detailed Description

Specialization of TagParser::VorbisComment for Vorbis comments inside an OGG stream.

Definition at line 69 of file oggcontainer.h.

Constructor & Destructor Documentation

◆ OggVorbisComment()

TagParser::OggVorbisComment::OggVorbisComment ( )

inline

Constructs a new OGG Vorbis comment.

Definition at line 91 of file oggcontainer.h.

Member Function Documentation

◆ oggParams() [1/2]

OggParameter & TagParser::OggVorbisComment::oggParams ( )

inline

Returns the OGG parameter for the comment.

Consists of first page index, first segment index, last page index, last segment index and tag index (in this order). These values are used and managed by the OggContainer class and do not affect the behavior of the VorbisComment instance.

Definition at line 118 of file oggcontainer.h.

◆ oggParams() [2/2]

const OggParameter & TagParser::OggVorbisComment::oggParams ( ) const

inline

Returns the OGG parameter for the comment.

Consists of first page index, first segment index, last page index, last segment index and tag index (in this order). These values are used and managed by the OggContainer class and do not affect the behavior of the VorbisComment instance.

Definition at line 129 of file oggcontainer.h.

◆ supportsTarget()

bool TagParser::OggVorbisComment::supportsTarget ( ) const

inlineoverridevirtual

Returns true; the target is used to specify the stream.

Remarks: At this point, one cannot move a tag from one stream to another by changing the target. So the target is only evaluated when invoking createTag() and added to parsed tags for informative purposes.

See also: OggContainer::createTag(), TagTarget

Reimplemented from TagParser::Tag.

Definition at line 107 of file oggcontainer.h.

◆ type()

TagType TagParser::OggVorbisComment::type ( ) const

inlineoverridevirtual

Returns the type of the tag as TagParser::TagType.

This is TagType::Unspecified by default and might be overwritten when subclassing.

Reimplemented from TagParser::FieldMapBasedTag< VorbisComment >.

Definition at line 95 of file oggcontainer.h.

◆ typeName()

std::string_view TagParser::OggVorbisComment::typeName ( ) const

overridevirtual

Returns the type name of the tag as C-style string.

This is "unspecified" by default and might be overwritten when subclassing.

Reimplemented from TagParser::FieldMapBasedTag< VorbisComment >.

Definition at line 25 of file oggcontainer.cpp.
