Detailed Description

Allows reading of values from configuration files This class allows a module to read from either the main configuration file (inspircd.conf) or from a module-specified configuration file.

It may either be instantiated with one parameter or none. Constructing the class using one parameter allows you to specify a path to your own configuration file, otherwise, inspircd.conf is read.

Constructor & Destructor Documentation

ConfigReader::ConfigReader (    ) 
 

Default constructor.

This constructor initialises the ConfigReader class to read the inspircd.conf file as specified when running ./configure.

Definition at line 319 of file modules.cpp.

References cache, and error. 

00320 {
00321         this->cache = new std::stringstream(std::stringstream::in | std::stringstream::out);
00322         this->error = LoadConf(CONFIG_FILE,this->cache);
00323 }

ConfigReader::ConfigReader (  std::string    filename ) 
 

Overloaded constructor.

This constructor initialises the ConfigReader class to read a user-specified config file

Definition at line 333 of file modules.cpp.

References cache, and error. 

00334 {
00335         this->cache = new std::stringstream(std::stringstream::in | std::stringstream::out);
00336         this->error = LoadConf(filename.c_str(),this->cache);
00337 };

ConfigReader::~ConfigReader (    ) 
 

Default destructor.

This method destroys the ConfigReader class.

Definition at line 326 of file modules.cpp.

References cache. 

00327 {
00328         if (this->cache)
00329                 delete this->cache;

Member Function Documentation

int ConfigReader::Enumerate (  std::string    tag ) 
 

Counts the number of times a given tag appears in the config file.

This method counts the number of times a tag appears in a config file, for use where there are several tags of the same kind, e.g. with opers and connect types. It can be used with the index value of ConfigReader::ReadValue to loop through all copies of a multiple instance tag.

Definition at line 347 of file modules.cpp. 

00348 {
00349         return EnumConf(cache,tag.c_str());
00350 }

int ConfigReader::EnumerateValues (  std::string    tag,
int    index
) 
 

Returns the number of items within a tag.

For example if the tag was <test tag="blah" data="foo"> then this function would return 2. Spaces and newlines both qualify as valid seperators between values.

Definition at line 352 of file modules.cpp. 

00353 {
00354         return EnumValues(cache, tag.c_str(), index);
00355 }

std::string ConfigReader::ReadValue (  std::string    tag,
std::string    name,
int    index
) 
 

Retrieves a value from the config file.

This method retrieves a value from the config file. Where multiple copies of the tag exist in the config file, index indicates which of the values to retrieve.

Definition at line 339 of file modules.cpp. 

00340 {
00341         char val[MAXBUF];
00342         ReadConf(cache,tag.c_str(),name.c_str(),index,val);
00343         return val;
00344 }

bool ConfigReader::Verify (    ) 
 

Returns true if a config file is valid.

This method is partially implemented and will only return false if the config file does not exist or could not be opened.

Definition at line 357 of file modules.cpp.

References error. 

00358 {
00359         return this->error;

Member Data Documentation

std::stringstream* ConfigReader::cache [protected]
 

The contents of the configuration file This protected member should never be accessed by a module (and cannot be accessed unless the core is changed).

It will contain a pointer to the configuration file data with unneeded data (such as comments) stripped from it.
