virtual sdf::Param::~Param ( )

virtual

Destructor.

Member Function Documentation

Param* 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] _value The value of the parameter.

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

References sdf::ParamPrivate::key, sdferr, sdf::ParamPrivate::typeName, and sdf::ParamPrivate::value.

Referenced by sdf::Element::Get().

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

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

Parameters

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

Returns: True if successfully set _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] _value The default value of the parameter.

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

References sdf::ParamPrivate::defaultValue, sdf::ParamPrivate::key, sdferr, and sdf::ParamPrivate::typeName.

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::type_info& sdf::Param::GetType ( ) const

Get the type of the value stored.

Returns: The std::type_info.

Deprecated:

GetType is unstable. Use IsType().

See Also: IsType

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.

References sdf::ParamPrivate::value.

Param& sdf::Param::operator= ( const Param & _param )

Equal operator.

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

Parameters

[in] _param The parameter to set values from.

Returns: *This

void sdf::Param::Reset ( )

Reset the parameter to the default value.

template<typename T >

bool sdf::Param::Set ( const T & _value )

Set the parameter's value.

The passed in value must conform to the boost::lexical_cast spec. This means the value must have an input and output stream operator.

Parameters

[in] _value The value to set the parameter to.

Returns: True if the value was successfully set.

References sdf::ParamPrivate::key, sdferr, and SetFromString().

Referenced by sdf::Element::Set().

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

Set the description of the parameter.

Parameters

[in] _desc New description for the parameter.

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

Set the parameter value from a string.

Parameters

[in] _value New value for the parameter in string form.

Referenced by Set().

template<typename T >

void sdf::Param::SetUpdateFunc ( T _updateFunc )

Set the update function.

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

Parameters

[in] _updateFunc Function pointer to an update function.

References sdf::ParamPrivate::updateFunc.

void sdf::Param::Update ( )

Set the parameter's value using the updateFunc.
