Help function for simple types.

const DtString& DtBaseConfigVariable::description ( ) const

inline

virtual void DtBaseConfigVariable::getCommandLineArg ( DtCmdLine::CmdLine &  cmdLine )

pure virtual

Get an arg.

This this var doesn't support Arguments return a NULL pointer.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

virtual void DtBaseConfigVariable::getEnvironmentSchemaType ( DtEnvironment  env, TypeSet &  usedTypes  ) const

pure virtual

Get an environment value which represents the XML scheme type.

The var should check the type set before created type to eliminate duplicates.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

virtual DtEnvValueSP DtBaseConfigVariable::getEnvironmentValue ( DtEnvironment  env )

pure virtual

Get an environment value which represent the value of the var.

If the var type does not support environment representation a NULL smart pointer should be returned.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

bool DtBaseConfigVariable::inCommandLine ( ) const

inline

Is this var used in the command line.

bool DtBaseConfigVariable::inConfigFile ( ) const

inline

Is this var used in the config line.

virtual bool DtBaseConfigVariable::isRequired ( ) const

pure virtual

Check to see if the value is required.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

bool DtBaseConfigVariable::isSet ( ) const

inline

Check to see if the value has been set.

virtual const DtString& DtBaseConfigVariable::name ( ) const

pure virtual

Get the Var's name.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

DtBaseConfigVariable& DtBaseConfigVariable::operator=

(

const DtBaseConfigVariable &

other

)

Assignment operator.

Assigns all defining attributes of the variable. The variable's group that it belongs to remains unchanged.

DtVariableScope DtBaseConfigVariable::scope ( ) const

inline

Get the scope of this variable.

virtual DtString DtBaseConfigVariable::type ( ) const

pure virtual

Get the Var's type.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

virtual void DtBaseConfigVariable::updateFromCommandLineArg ( )

pure virtual

Update the value by its argument.

This function will not be called if getArg returns NULL.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

virtual void DtBaseConfigVariable::updateFromEnvironment ( DtEnvironment  env )

pure virtual

Synchronize the var with an environment.

This function will not be called if getEnvironmentValue() returns NULL.

Implemented in DtConfigVariable< T >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtConfigVariable< DtVector64 >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.
