Member Function Documentation

◆ Instance()

static DuckConfigFile* ts::DuckConfigFile::Instance ( )
static

Get the instance of the singleton of this class.

Returns
The instance of the singleton of this class.

◆ value()

UString ts::DuckConfigFile::value ( const UString &  entry,
const UString &  defvalue = UString() 
) const

Get the value of an entry.

A section with the name of the executable is searched first. Then, the global section is used.

Parameters
[in]entryEntry name.
[in]defvalueDefault value.
Returns
The value in the entry or defvalue if entry does not exist.

◆ getValues()

void ts::DuckConfigFile::getValues ( const UString &  entry,
UStringVector &  values 
) const

Get all values of an entry.

A section with the name of the executable is searched first. Then, the global section is used.

Parameters
[in]entryEntry name.
[out]valuesVector of values.

◆ DefaultFileName()

static UString ts::ConfigFile::DefaultFileName ( FileStyle  style = LOCAL_SYSTEM,
const UString &  name = UString() 
)
staticinherited

Get the default configuration file name.

Parameters
[in]styleSystem style for file name.
[in]nameApplication name (default: executable base name).
Returns
The default configuration file name for the application.

◆ fileName()

UString ts::ConfigFile::fileName ( ) const
inlineinherited

Get the latest loaded file.

Returns
The name of the latest loaded file.

◆ load()

bool ts::ConfigFile::load ( const UString &  filename,
Report &  report = (*(static_cast< ts::Report * >(ts::CerrReport::Instance()))) 
)
inherited

Reload the configuration from a file.

Parameters
[in]filenameA file name to read.
[in,out]reportWhere to report errors.
Returns
True on success, false on error.

◆ merge() [1/2]

bool ts::ConfigFile::merge ( const UString &  filename,
Report &  report = (*(static_cast< ts::Report * >(ts::CerrReport::Instance()))) 
)
inherited

Merge the configuration from a file.

The values which are read from the specified file override previous values.

Parameters
[in]filenameA file name to read.
[in,out]reportWhere to report errors.
Returns
True on success, false on error.

◆ merge() [2/2]

void ts::ConfigFile::merge ( std::istream &  strm)
inherited

Merge the configuration from a file.

The values which are read from the specified file override previous values.

Parameters
[in,out]strmOpened input text stream to read the configuration file.

◆ save() [1/2]

bool ts::ConfigFile::save ( const UString &  filename = UString(),
Report &  report = (*(static_cast< ts::Report * >(ts::CerrReport::Instance()))) 
) const
inherited

Save a configuration file.

Parameters
[in]filenameA file name to write. If no file name is specified, use the file name from constructor or last load() or merge().
[in,out]reportWhere to report errors.
Returns
True on success, false on error.

◆ save() [2/2]

std::ostream& ts::ConfigFile::save ( std::ostream &  strm) const
inherited

Save a configuration file in a stream.

Parameters
[in,out]strmOpened output text stream to write the configuration file.
Returns
A reference to strm.

◆ sectionCount()

size_t ts::ConfigFile::sectionCount ( ) const
inlineinherited

Get the number of sections in the file.

Returns
The number of sections in the file.

◆ getSectionNames()

void ts::ConfigFile::getSectionNames ( UStringVector &  names) const
inherited

Get the names of all sections.

Parameters
[out]namesReturned names of all sections.

◆ section() [1/2]

ConfigSection& ts::ConfigFile::section ( const UString &  name)
inlineinherited

Get a reference to a section inside the configuration file instance.

Create the section if it does not exist.

Parameters
[in]nameThe section name.
Returns
A reference to the section.

◆ section() [2/2]

const ConfigSection& ts::ConfigFile::section ( const UString &  name) const
inherited

Get a reference to a section inside the configuration file instance.
