Detailed Description
Introspective access to data in a channel.
The DCOWriter accesses the data in a channel. These objects should be created on the stack, and when they go out of scope, the access to the channel is released again.
A DCOWriter is an alternative to using a DataWriter. This variant is for generic, introspective access, using a DataWriter is much more efficient when you can program for the data type.
Constructor & Destructor Documentation
◆ DCOWriter() [1/3]
| dueca::DCOWriter::DCOWriter | ( | const char * | classname, |
| ChannelWriteToken & | token, | ||
| const DataTimeSpec & | ts ) |
Constructor.
Note that these objects are light-weight, and meant to be constructed (on the stack) and discarded.
- Parameters
-
classname Type of data to be read; must match the data type in the entry accessed with the write token. token Read token. ts Time specification.
◆ DCOWriter() [2/3]
| dueca::DCOWriter::DCOWriter | ( | ChannelWriteToken & | token, |
| const DataTimeSpec & | ts ) |
Constructor.
Note that these objects are light-weight, and meant to be constructed (on the stack) and discarded. This version assumes the data type from the channel entry.
- Parameters
-
token Write token. ts Time specification.
◆ DCOWriter() [3/3]
| dueca::DCOWriter::DCOWriter | ( | ChannelWriteToken & | token, |
| TimeTickType | ts = SimTime::getTimeTick() ) |
Constructor with time tick, for event writing.
Note that these objects are light-weight, and meant to be constructed (on the stack) and discarded. This version assumes the data type from the channel entry.
- Parameters
-
token Write token. ts Time specification, if omitted, takes current tick.
