Member Typedef Documentation

◆ K

An abbreviation for our row index constants.

Constructor & Destructor Documentation

◆ AcrobotInput() [1/3]

Default constructor.

Sets all rows to their default value:

  • tau defaults to 0.0 Nm.

◆ AcrobotInput() [2/3]

AcrobotInput ( const AcrobotInput< T > &  other)

◆ AcrobotInput() [3/3]

AcrobotInput ( AcrobotInput< T > &&  other)
noexcept

Member Function Documentation

◆ DoClone()

AcrobotInput<T>* DoClone ( ) const
finalvirtual

Returns a new BasicVector containing a copy of the entire vector.

Caller must take ownership, and may rely on the NVI wrapper to initialize the clone elementwise.

Subclasses of BasicVector must override DoClone to return their covariant type.

Reimplemented from BasicVector< T >.

◆ GetCoordinateNames()

static const std::vector<std::string>& GetCoordinateNames ( )
static

◆ IsValid()

drake::boolean<T> IsValid ( ) const

Returns whether the current values of this vector are well-formed.

◆ operator=() [1/2]

AcrobotInput& operator= ( const AcrobotInput< T > &  other)

◆ operator=() [2/2]

AcrobotInput& operator= ( AcrobotInput< T > &&  other)
noexcept

◆ Serialize()

void Serialize ( Archive *  a)

Visit each field of this named vector, passing them (in order) to the given Archive.

The archive can read and/or write to the vector values. One common use of Serialize is the //common/yaml tools.

◆ set_tau()

void set_tau ( const T &  tau)

Setter that matches tau().

◆ SetToNamedVariables()

std::enable_if_t<std::is_same_v<U, symbolic::Expression> > SetToNamedVariables ( )

Create a symbolic::Variable for each element with the known variable name.

This is only available for T == symbolic::Expression.

◆ tau()

const T& tau ( ) const

Torque at the elbow.

Note
tau is expressed in units of Nm.

◆ with_tau()

AcrobotInput<T> with_tau ( const T &  tau) const

Fluent setter that matches tau().

Returns a copy of this with tau set to a new value.
