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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtVariableGroup, DtMultiConfigVariable< T >, and DtMultiConfigVariable< DtString >.

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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtMultiConfigVariable< T >, DtVariableGroup, and DtMultiConfigVariable< DtString >.

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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtVariableGroup, DtMultiConfigVariable< T >, and DtMultiConfigVariable< DtString >.

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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, 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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtMultiConfigVariable< T >, DtMultiConfigVariable< DtString >, and DtVariableGroup.

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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, 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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtMultiConfigVariable< T >, DtVariableGroup, and DtMultiConfigVariable< DtString >.

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< DtVector >, DtConfigVariable< double >, DtConfigVariable< DtString >, DtConfigVariable< int >, DtConfigVariable< bool >, DtVariableGroup, DtMultiConfigVariable< T >, and DtMultiConfigVariable< DtString >.
