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

| 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.
Reimplemented in RTT::internal::ChannelBufferElement< T >, and RTT::internal::ChannelDataElement< 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().
Reimplemented from RTT::base::ChannelElementBase.
Definition at line 59 of file ChannelElement.hpp.
| shared_ptr RTT::base::ChannelElement< T >::getOutput | ( | ) | [inline] |
Returns the next channel element in the channel's propagation direction
Reimplemented from RTT::base::ChannelElementBase.

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