const std::string &  _default,
bool  _required,
const std::string &  _description = "" 
)

Constructor.

Parameters
[in]_keyKey for the parameter.
[in]_typeNameString name for the value type (double, int,...).
[in]_defaultDefault value.
[in]_requiredTrue if the parameter is required to be set.
[in]_descriptionDescription of the parameter.
Exceptions

Destructor.

Member Function Documentation

◆ Clone()

ParamPtr sdf::v9::Param::Clone ( ) const

Clone the parameter.

Returns
A new parameter that is the clone of this.

◆ Get()

template<typename T >
bool sdf::v9::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.

◆ GetAny()

bool sdf::v9::Param::GetAny ( std::any &  _anyVal) const

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

Parameters
[out]_anyValThe std::any object to set.
Returns
True if successfully fetched _anyVal, false otherwise.

◆ GetAsString()

std::string sdf::v9::Param::GetAsString ( ) const

Get the value as a string.

Returns
String containing the value of the parameter.

◆ GetDefault()

template<typename T >
bool sdf::v9::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.

◆ GetDefaultAsString()

std::string sdf::v9::Param::GetDefaultAsString ( ) const

Get the default value as a string.

Returns
String containing the default value of the parameter.

◆ GetDescription()

std::string sdf::v9::Param::GetDescription ( ) const

Get the description of the parameter.

Returns

◆ GetKey()

const std::string& sdf::v9::Param::GetKey ( ) const

Get the key value.

Returns
The key.

◆ GetRequired()

bool sdf::v9::Param::GetRequired ( ) const

Return whether the parameter is required.

Returns
True if the parameter is required.

◆ GetSet()

bool sdf::v9::Param::GetSet ( ) const

Return true if the parameter has been set.

Returns
True if the parameter has been set.

◆ GetTypeName()

const std::string& sdf::v9::Param::GetTypeName ( ) const

Get the type name value.

Returns
The type name.

◆ IsType()

template<typename Type >
bool sdf::v9::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.

◆ operator=()

Param& sdf::v9::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

◆ Reset()

void sdf::v9::Param::Reset ( )

Reset the parameter to the default value.

◆ Set()

template<typename T >
bool sdf::v9::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.

◆ SetDescription()

void sdf::v9::Param::SetDescription ( const std::string &  _desc)

Set the description of the parameter.

Parameters
[in]_descNew description for the parameter.

◆ SetFromString()

bool sdf::v9::Param::SetFromString ( const std::string &  _value)

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

◆ SetUpdateFunc()

template<typename T >
void sdf::v9::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.

◆ Update()

void sdf::v9::Param::Update ( )

Set the parameter's value using the updateFunc.
