Detailed Description
template<typename T>
class RTT::internal::ConstantDataSource< T >
A DataSource which holds a constant value and returns it in its get() method. It can not be changed after creation.
- Parameters
-
T Any type of data, except being a non-const reference.

Member Function Documentation
|
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< T >.
|
virtual |
Implements RTT::internal::DataSource< T >.
|
inlinevirtual |
Return the data as type T.
Implements RTT::internal::DataSource< T >.
Definition at line 130 of file DataSources.hpp.
|
inlinevirtual |
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< T >.
Definition at line 140 of file DataSources.hpp.
|
inlinevirtual |
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< T >.
Definition at line 135 of file DataSources.hpp.
Member Data Documentation
|
private |
Assure that mdata is const, such that T is forced to not be a non-const reference.
