Public Methods

Param(char Type)

Base constructor.

virtual ~Param(void)

Destructor.

virtual operator int() const

Cast parameter value to integer.

virtual operator double() const

Cast parameter value to dounble precision float.

virtual operator std::string() const

Cast parameter value to atring.

virtual int operator=(int x)

Set parameter value to integer.

virtual double operator=(double x)

Set parameter value to integer.

virtual std::string operator=(const std::string& x)

Set parameter value to integer.

virtual std::ostream& Write(std::ostream& ostr)

Write the parameter value.

const char* getType(void) const

Get the parameter type.

Param(char Type)

Base constructor.

Parameters:

Type - character indicating object type.

virtual ~Param(void)

Destructor.

virtual operator int() const

Cast the parameter value to a integer. If the parameter can't be converted to integer, 0 is returned.

Returns:

Parameter value converted to an integer.

virtual operator double() const

Cast the parameter value to a double precision float. If the parameter can't be converted to a float, 0.0 is returned.

Returns:

Parameter value converted to float.

virtual operator std::string() const

Cast the parameter value to a string.

Returns:

Parameter value converted to a atring.

virtual int operator=(int x)

Set the parameter to an integer value. The argument is converted to the parameter type if necessary. The parameter type remains unchanged.

Returns:

Parameter value converted to an integer.

virtual double operator=(double x)

Set the parameter to an double float value. The argument is converted to the parameter type if necessary. The parameter type remains unchanged.

Returns:

Parameter value converted to an integer.

virtual std::string operator=(const std::string& x)

Set the parameter to a string value. The argument is converted to the parameter type if necessary. The parameter type remains unchanged.

Returns:

Parameter value converted to an integer.

virtual std::ostream& Write(std::ostream& ostr)

Write the parameter value to the specified output stream.

Returns:

Reference to the output stream.

const char* getType(void) const

Get the parameter type character.

Returns:

Pointer to a character string containing the character type.
