Last updated: 8th July 1999 at 10:49 BST

This package defines the "feather::container" interface and some commands which use that interface.

Interface

The interface contains the following members.

Tcl_Obj *(*get) (Tcl_Interp *interp, Tcl_Obj *container, Tcl_Obj *element);: Returns the value associated with the element in the container.
set: Creates an association between the element and the value in the container.
unset: Removes the association between the element and its value in the container.
exists: Checks whether there is an association between the element and a value in the container. Returns 1 if there is and 0 if not.
length: Returns the length of the container. i.e. the number of elements in the container.
begin: Returns an iterator object which refers to the start of the container. It can be used to iterate over the container in the forward direction.
end: Returns an iterator object which refers to the end of the container. It is used to check whether the iteration has completed.
