Returns: A new parameter that is the clone of this.

◆ Get()

template<typename T >

bool sdf::v11::Param::Get ( T & _value ) const

Get the value of the parameter.

Parameters

[out] _value The value of the parameter.

Returns: True if parameter was successfully cast to the value type passed in.

References sdferr.

◆ GetAny()

bool sdf::v11::Param::GetAny ( std::any & _anyVal ) const

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

Parameters

[out] _anyVal The std::any object to set.

Returns: True if successfully fetched _anyVal, false otherwise.

◆ GetAsString()

std::string sdf::v11::Param::GetAsString ( ) const

Get the value as a string.

Returns: String containing the value of the parameter.

◆ GetDefault()

template<typename T >

bool sdf::v11::Param::GetDefault ( T & _value ) const

Get the default value of the parameter.

Parameters

[out] _value The default value of the parameter.

Returns: True if parameter was successfully cast to the value type passed in.

References sdferr.

◆ GetDefaultAsString()

std::string sdf::v11::Param::GetDefaultAsString ( ) const
