NAME
page_util_flow - page dataflow/treewalker utility
SYNOPSIS
package require page::util::flow ?0.1?
package require snit
::page::util::flow start flowvar nodevar script
flow visit node
flow visitl nodelist
flow visita node...
_________________________________________________________________
DESCRIPTION
This package provides a single utility command for easy dataflow based manipulation of arbitrary data structures, especially abstract syn-
tax trees.
API
::page::util::flow start flowvar nodevar script
This command contains the core logic to drive the walking of an arbitrary data structure which can partitioned into separate parts.
Examples of such structures are trees and graphs.
The command makes no assumptions at all about the API of the structure to be walked, except that that its parts, here called nodes,
are identified by strings. These strings are taken as is, from the arguments, and the body, and handed back to the body, without
modification.
Access to the actual data structure, and all decisions regarding which nodes to visit in what order are delegated to the body of the
loop, i.e. the script.
The body is invoked first for the nodes in the start-set specified via start), and from then on for the nodes the body has requested
to be visited. The command stops when the set of nodes to visit becomes empty. Note that a node can be visited more than once. The
body has complete control about this.
The body is invoked in the context of the caller. The variable named by nodevar will be set to the current node, and the variable
named by flowvar will be set to the command of the flow object through which the body can request the nodes to visit next. The API
provided by this object is described in the next section, FLOW API.
Note that the command makes no promises regarding the order in which nodes are visited, excpt that the nodes requested to be visited
by the current iteration will be visited afterward, in some order.
FLOW API
This section describes the API provided by the flow object made accessible to the body script of ::page::util::flow.
flow visit node
Invoking this method requests that the node n is visited after the current iteration.
flow visitl nodelist
Invoking this method requests that all the nodes found in the list nodelist are visited after the current iteration.
flow visita node...
This is the variadic arguments form of the method visitl, see above.
