◆ GetParentElement()

ElementPtr sdf::SDF_VERSION_NAMESPACE::Param::GetParentElement ( ) const

Get the parent Element of this Param.

Returns
Pointer to this Param's parent Element, nullptr if there is no parent Element.

Move assignment operator.

Parameters
[in]_paramParam to move from
Returns
Reference to this

◆ Reparse()

bool sdf::SDF_VERSION_NAMESPACE::Param::Reparse ( )

Reparse the parameter value.

This should be called after the parent element's attributes have been modified, in the event that the value was set using SetFromString or posesses a default value, and that the final parsed value is dependent on the attributes of the parent element. For example, the rotation component of a pose element can be parsed as degrees or radians, depending on the attribute @degrees of the parent element. If however the value was explicitly set using the Set<T> function, reparsing would not change the value.

Returns
True if the parameter value has been reparsed successfully.

bool SetFromString(const std::string &_value)
bool Set(const T &_value)

◆ Reset()

void sdf::SDF_VERSION_NAMESPACE::Param::Reset ( )

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

◆ SetDescription()

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

Set the description of the parameter.

Parameters
[in]_descNew description for the parameter.

◆ SetFromString() [1/2]

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

Set the parameter value from a string.

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

◆ SetFromString() [2/2]

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

Set the parameter value from a string.

Parameters
[in]_valueNew value for the parameter in string form.
[in]_ignoreParentAttributesWhether to ignore parent element attributes when parsing value from string as well as subsequent reparses.

Referenced by Set().

◆ SetParentElement()

bool sdf::SDF_VERSION_NAMESPACE::Param::SetParentElement ( ElementPtr  _parentElement)

Set the parent Element of this Param.

Parameters
[in]_parentElementPointer to new parent Element. A nullptr can provided to remove the current parent Element.
Returns
True if the parent Element was set and the value was reparsed successfully.

◆ SetUpdateFunc()

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

Set the update function.

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