tcl::chan::variable — In-memory channel using variable for storage
package require Tcl 8.5
package require TclOO
package require tcl::chan::events ?1?
package require tcl::chan::variable ?1?
The tcl::chan::variable package provides a command creating channels which live purely in memory. They provide random-access, i.e. are seekable. In contrast to the channels created by tcl::chan::memchan the data is not hidden in the channel however, but stored in an associated variable, specified at the time of construction.
Packages related to this are tcl::chan::memchan and tcl::chan::string.
The internal TclOO class implementing the channel handler is a sub-class of the tcl::chan::events framework.
- ::tcl::chan::variable varname
This command creates a new variable channel and returns its handle. The content of the channel is stored in the associated namespace variable varname.
