Detailed Description

template<typename T>
class RTT::base::ChannelElement< T >

A typed version of ChannelElementBase. It defines generic methods that are type-specific (like write and read)

Definition at line 53 of file ChannelElement.hpp.

Member Function Documentation

template<typename T>
virtual value_t RTT::base::ChannelElement< T >::data_sample (  )  [inline, virtual]
template<typename T>
virtual bool RTT::base::ChannelElement< T >::data_sample ( param_t  sample  )  [inline, virtual]

Provides a data sample to initialize this connection. This is used before the first write() in order to inform this connection of the size of the data. As such enough storage space can be allocated before the actual writing begins.

Returns:
false if an error occured that requires the channel to be invalidated.

Reimplemented in RTT::internal::ChannelBufferElement< T >, and RTT::internal::ChannelDataElement< T >.

Definition at line 73 of file ChannelElement.hpp.

template<typename T>
shared_ptr RTT::base::ChannelElement< T >::getInput (  )  [inline]

Returns the current input channel element. This will only return a valid channel element if another element has received this object as an argument to setOutput().

Returns:

Reimplemented from RTT::base::ChannelElementBase.

Definition at line 59 of file ChannelElement.hpp.

template<typename T>
shared_ptr RTT::base::ChannelElement< T >::getOutput (  )  [inline]

Returns the next channel element in the channel's propagation direction

Reimplemented from RTT::base::ChannelElementBase.

Definition at line 53 of file ChannelElement.hpp.

template<typename T>
virtual FlowStatus RTT::base::ChannelElement< T >::read ( reference_t  sample,
bool  copy_old_data 
) [inline, virtual]

Reads a sample from the connection. sample is a reference which will get updated if a sample is available. The method returns true if a sample was available, and false otherwise. If false is returned, then sample is not modified by the method

Reimplemented in RTT::internal::ChannelBufferElement< T >, and RTT::internal::ChannelDataElement< T >.

Definition at line 107 of file ChannelElement.hpp.

template<typename T>
virtual bool RTT::base::ChannelElement< T >::write ( param_t  sample  )  [inline, virtual]

Writes a new sample on this connection. sample is the sample to write.

Returns:
false if an error occured that requires the channel to be invalidated. In no ways it indicates that the sample has been received by the other side of the channel.

Reimplemented in RTT::internal::ChannelBufferElement< T >, and RTT::internal::ChannelDataElement< T >.
