Detailed Description

Interface of configuration token handler classes.

Classes implementing this interface configure the analysis according to a vector of configuration strings (tokens) read from a single line of a text file.

Derived classes handles a specific text file command and eventual sub-commands. Instances of derived classes are created by #TokenizedConfigLineHandler; to allow for automatic construction, derived classes must be registered in the ConfigurationTokensHandler Factory using the command name as the builder name.

Constructor & Destructor Documentation

ConfigurationTokensHandler()

EA::ConfigurationTokensHandler::ConfigurationTokensHandler ( AnalysisManager &  manager, const CommandLineParameters &  clParams  )

inlinevirtual

Destructor.

Member Function Documentation

HandleTokens()

virtual bool EA::ConfigurationTokensHandler::HandleTokens ( const std::vector< std::string > &  tokens )

pure virtual

Configures the analysis according to given tokens.

The configuration tokens are processed. If the token sequence is not understood (e.g. wrong command name) then the method should return false; this is a soft error signal, since other token handlers might be able to understand and process the command. In case of hard errors (wrong number/type of arguments, other errors generated during the execution) an exception is thrown.

Parameters

tokens

The configuration tokens.

Returns

false if the given token sequence is not understood and cannot be handled.

Exceptions

std::runtime_error

if error occurs during the handling (implementations may throw other kind of exceptions).

Implemented in EA::EventLoopConfigurationTokensHandler, EA::PersistenceConfigurationTokensHandler, and EA::DataProviderConfigurationTokensHandler.

SetParameter()

bool EA::ConfigurationTokensHandler::SetParameter ( const std::string &  name, const std::string &  value, Configurable &  obj  )

protected

Set a parameter of a given Configurable object.

Converts the parameter value from string to the correct type and then sets the value in the given Configurable object.
