Detailed Description

template<typename function>
class RTT::internal::UnaryDataSource< function >

A DataSource which returns the return value of a unary function. The return value of get() and the input argument are infered from the function signature type.

Member Typedef Documentation

template<typename function>

Definition at line 750 of file DataSources.hpp.

template<typename function>

typedef boost::intrusive_ptr<UnaryDataSource<function> > RTT::internal::UnaryDataSource< function >::shared_ptr

Use this type to store a pointer to a DataSourceBase.

Reimplemented from RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Definition at line 755 of file DataSources.hpp.

template<typename function>

typedef remove_cr<typename function::result_type>::type RTT::internal::UnaryDataSource< function >::value_t [private]

The bare type of T is extracted into value_t.

Reimplemented from RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Constructor & Destructor Documentation

template<typename function>

RTT::internal::UnaryDataSource< function >::UnaryDataSource	(	typename DataSource< arg_t >::shared_ptr	a,
		function	f
	)			`[inline]`

Create a DataSource which returns the return value of a function f which is given argument a.

Definition at line 761 of file DataSources.hpp.

Member Function Documentation

template<typename function>

virtual UnaryDataSource<function>* RTT::internal::UnaryDataSource< function >::clone ( ) const [inline, virtual]

Return a shallow clone of this DataSource. This method returns a duplicate of this instance which re-uses the DataSources this internal::DataSource holds reference to. The clone() function is thus a non-deep copy.

Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Definition at line 787 of file DataSources.hpp.

template<typename function>

virtual UnaryDataSource<function>* RTT::internal::UnaryDataSource< function >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > & alreadyCloned ) const [inline, virtual]

Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Definition at line 792 of file DataSources.hpp.

template<typename function>

virtual value_t RTT::internal::UnaryDataSource< function >::get ( ) const [inline, virtual]

Return the data as type T.

Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Definition at line 766 of file DataSources.hpp.

template<typename function>

void RTT::internal::UnaryDataSource< function >::reset ( void ) [inline, virtual]

Reset the data to initial values.

Reimplemented from RTT::base::DataSourceBase.

Definition at line 782 of file DataSources.hpp.

template<typename function>

DataSource<value_t>::const_reference_t RTT::internal::UnaryDataSource< function >::rvalue ( ) const [inline, virtual]

Get a const reference to the value of this DataSource. You must call evaluate() prior to calling this function in order to get the most recent value of this attribute.

Note:: Getting a reference to an internal data structure is not thread-safe.

Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Definition at line 776 of file DataSources.hpp.

template<typename function>

virtual value_t RTT::internal::UnaryDataSource< function >::value ( ) const [inline, virtual]

Return the result of the last evaluate() function. You must call evaluate() prior to calling this function in order to get the most recent value of this attribute.

Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.
