Detailed Description

Attributes of a tag in an HLS playlist.

Constructor & Destructor Documentation

TagAttributes()

ts::hls::TagAttributes::TagAttributes

(

const UString &

params = UString()

)

Constructor.

Parameters

[in]

params

String parameter of the tag in the playlist line.

Member Function Documentation

reload()

void ts::hls::TagAttributes::reload

(

const UString &

params = UString()

)

Reload the contents of the attributes.

Parameters

[in]

params

String parameter of the tag in the playlist line.

clear()

void ts::hls::TagAttributes::clear ( )

inline

Clear the content of the attributes.

present()

bool ts::hls::TagAttributes::present

(

const UString &

name

)

const

Check if an attribute is present.

Parameters

[in]

name

Attribute name.

Returns

True if the attribute is present.

value()

UString ts::hls::TagAttributes::value	(	const UString &	name,
		const UString &	def_value = UString() ) const

Get the value of a string attribute.

Parameters

[in]	name	Attribute name.
[in]	def_value	Default value if not present.

Returns

Attribute value.

getIntValue()

template<typename INT>
requires std::integral<INT>

void ts::hls::TagAttributes::getIntValue ( INT & val, const UString & name, INT def_value = static_cast<INT>(0) ) const

inline

Get the value of an integer attribute.

Template Parameters

INT	An integer type.

Parameters

[out]	val	Decoded value.
[in]	name	Attribute name.
[in]	def_value	Default value if not present.

getValue()

template<class NUMBER>
requires std::derived_from<NUMBER, AbstractNumber>

void ts::hls::TagAttributes::getValue ( NUMBER & val, const UString & name, const NUMBER & def_value = NUMBER() ) const

inline

Get the value of an AbstractNumber attribute.

Template Parameters

NUMBER

A subclass of AbstractNumber.

Parameters

[out]	val	Decoded value.
[in]	name	Attribute name.
[in]	def_value	Default value if not present.

getMilliValue()

template<typename INT>
requires std::integral<INT>

void ts::hls::TagAttributes::getMilliValue ( INT & val, const UString & name, INT def_value = static_cast<INT>(0) ) const

inline

Get the value of a numerical attribute in milli-units.

Template Parameters

INT	An integer type.

Parameters

[out]	val	Decoded value. If the value is an integer, return this value times 1000. If the value is a decimal one, use 3 decimal digits. Examples: "90" -> 90000, "1.12" -> 1120, "32.1234" -> 32123.
[in]	name	Attribute name.
[in]	def_value	Default value if not present.

ToMilliValue() [1/2]

template<typename INT>
requires std::integral<INT>

bool ts::hls::TagAttributes::ToMilliValue ( INT & value, const UString & str )

inlinestatic

Get the value of a String in milli-units.

Template Parameters

INT	An integer type.

Parameters

[out]	value	Decoded value. If the value is an integer, return this value times 1000. If the value is a decimal one, use 3 decimal digits. Examples: "90" -> 90000, "1.12" -> 1120, "32.1234" -> 32123.
[in]	str	String to decode.

Returns

True on success, false on error.

ToMilliValue() [2/2]

template<class Rep, class Period>

bool ts::hls::TagAttributes::ToMilliValue ( cn::duration< Rep, Period > & value, const UString & str )

inlinestatic

Get the value of a String in milli-units of a std::chrono::duration type.

Parameters

[out]	value	Decoded value. If the value is an integer, return this value times 1000. If the value is a decimal one, use 3 decimal digits. Examples: "90" -> 90000, "1.12" -> 1120, "32.1234" -> 32123.
[in]	str	String to decode.

Returns

True on success, false on error.
