struct::map - Manage key/value maps
package require struct::map ?1?
mapName method ?arg arg ...?
mapName set name ?value?
mapName unset ?pattern...?
Provides a snit class whose instances manage a key/value map. In other words, an object wrapper around Tcl arrays.
The main command provides construction of maps:
- ::struct::map mapName
- 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:
- mapName method ?arg arg ...?
- method and arguments determine the exact behavior of the command.
- 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:
- mapName get
- Returns the entire map as a Tcl dictionary.
- mapName names
- Returns the list of all keys known to the map, in arbitrary order.
- mapName set name ?value?
- 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.
- mapName unset ?pattern...?
- 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.
