Destructor.

Member Function Documentation

ParamPtr sdf::Param::Clone ( ) const

Clone the parameter.

Returns
A new parameter that is the clone of this.
template<typename T >
bool sdf::Param::Get ( T &  _value) const

Get the value of the parameter.

Parameters
[out]_valueThe value of the parameter.
Returns
True if parameter was successfully cast to the value type passed in.

References sdferr.

bool sdf::Param::GetAny ( boost::any &  _anyVal) const

Get the value of the parameter as a boost::any.

Parameters
[out]_anyValThe boost::any object to set.
Returns
True if successfully fetched _anyVal, false otherwise.
std::string sdf::Param::GetAsString ( ) const

Get the value as a string.

Returns
String containing the value of the parameter.
template<typename T >
bool sdf::Param::GetDefault ( T &  _value) const

Get the default value of the parameter.

Parameters
[out]_valueThe default value of the parameter.
Returns
True if parameter was successfully cast to the value type passed in.

References sdferr.

std::string sdf::Param::GetDefaultAsString ( ) const

Get the default value as a string.

Returns
String containing the default value of the parameter.
std::string sdf::Param::GetDescription ( ) const

Get the description of the parameter.

Returns
The description of the parameter.
const std::string& sdf::Param::GetKey ( ) const

Get the key value.

Returns
The key.
bool sdf::Param::GetRequired ( ) const

Return whether the parameter is required.

Returns
True if the parameter is required.
bool sdf::Param::GetSet ( ) const

Return true if the parameter has been set.

Returns
True if the parameter has been set.
const std::string& sdf::Param::GetTypeName ( ) const

Get the type name value.

Returns
The type name.
template<typename Type >
bool sdf::Param::IsType ( ) const

Return true if the param is a particular type.

Returns
True if the type held by this Param matches the Type template parameter.
Param& sdf::Param::operator= ( const Param _param)

Equal operator.

Set's the value and default value from the provided Param.

Parameters
[in]_paramThe parameter to set values from.
Returns
*This
void sdf::Param::Reset ( )

template<typename T >
bool sdf::Param::Set ( const T &  _value)

Set the parameter's value.

The passed in value value must have an input and output stream operator.

Parameters
[in]_valueThe value to set the parameter to.
Returns
True if the value was successfully set.

References sdferr, and SetFromString().

void sdf::Param::SetDescription ( const std::string &  _desc)

Set the description of the parameter.

Parameters
[in]_descNew description for the parameter.
bool sdf::Param::SetFromString ( const std::string &  _value)

Set the parameter value from a string.

Parameters
[in]_valueNew value for the parameter in string form.

Referenced by Set().

template<typename T >
void sdf::Param::SetUpdateFunc ( _updateFunc)

Set the update function.

The updateFunc will be used to set the parameter's value when Param::Update is called.

Parameters
[in]_updateFuncFunction pointer to an update function.
void sdf::Param::Update ( )

Set the parameter's value using the updateFunc.
