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]paramsString 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]paramsString parameter of the tag in the playlist line.

◆ present()

bool ts::hls::TagAttributes::present ( const UString name) const

Check if an attribute is present.

Parameters
[in]nameAttribute name.
Returns
True if the attribute is present.

◆ value()

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

Get the value of a string attribute.

Parameters
[in]nameAttribute name.
[in]defValueDefault 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  defValue = static_cast<INT>(0) 
) const
inline

Get the value of an integer attribute.

Template Parameters
INTAn integer type.
Parameters
[out]valDecoded value.
[in]nameAttribute name.
[in]defValueDefault 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 &  defValue = NUMBER() 
) const
inline

Get the value of an AbstractNumber attribute.

Template Parameters
NUMBERA subclass of AbstractNumber.
Parameters
[out]valDecoded value.
[in]nameAttribute name.
[in]defValueDefault value if not present.

◆ getMilliValue()

template<typename INT >
requires std::integral<INT>
void ts::hls::TagAttributes::getMilliValue ( INT val,
const UString name,
INT  defValue = static_cast<INT>(0) 
) const
inline

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

Template Parameters
INTAn integer type.
Parameters
[out]valDecoded 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]nameAttribute name.
[in]defValueDefault value if not present.

◆ ToMilliValue() [1/2]

template<typename INT >
requires std::integral<INT>
static bool ts::hls::TagAttributes::ToMilliValue ( INT value,
const UString str 
)
inlinestatic

Get the value of a String in milli-units.

Template Parameters
INTAn integer type.
Parameters
[out]valueDecoded 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]strString to decode.
Returns
True on success, false on error.

◆ ToMilliValue() [2/2]

template<class Rep , class Period >
static 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]valueDecoded 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]strString to decode.
Returns
True on success, false on error.
