DESCRIPTION
Provides a snit class whose instances manage a key/value map. In other words, an object wrapper around Tcl arrays.
API
The main command provides construction of maps:
-
Creates a new, empty map with an associated global Tcl command whose name is mapName. It may be used to invoke various operations on the map. It has the following general form:
If mapName is specified as %AUTO% a unique name will be generated by the package itself. The result of the command is the fully-qualified name of the instance command.
The following commands are possible for map objects:
-
Returns the entire map as a Tcl dictionary.
-
Returns the list of all keys known to the map, in arbitrary order.
-
Sets key name to the specified value, if the value specified. Returns the value for the key. Throws an error if the key is not known.
-
Removes all keys matching at least one of the glob patterns from the map. If no pattern is specified all keys are removed. In other words, the default pattern is *. The result of the command is the empty string.
