GetChildrenList

Description

Provides a list of the children of a routine included in a trace tree model.

Applies to

TraceTreeObject, TraceTreeRoutine, and TraceTreeGarbageCollect objects

Syntax

instancename.GetChildrenList ( list )

Argument	Description
instancename	Instance name of the TraceTreeObject, TraceTreeRoutine, or TraceTreeGarbageCollect object.
list	An unbounded array variable of datatype TraceTreeNode in which GetChildrenList stores a TraceTreeNode object for each child of a routine. This argument is passed by reference.

Returns

ErrorReturn. Returns the following values:

Success!—The function succeeded
ModelNotExistsError!—The model does not exist

Usage

You use the GetChildrenList function to extract a list of the children of a routine (the classes and routines it calls) included in a trace tree model. Each child listed is defined as a TraceTreeNode object and provides the type of activity represented by that child.

You must have previously created the trace tree model from a trace file using the BuildModel function.

When the GetChildrenList function is called for TraceTreeGarbageCollect objects, each child listed usually represents the destruction of a garbage collected object.

Examples

Example 1

This example checks the activity type of a node included in the trace tree model. If the activity type is an occurrence of a routine, it determines the name of the class that contains the routine and provides a list of the classes and routines called by that routine:

TraceTree ltct_node

TraceTreeNode ltctn_list

...

CHOOSE CASE node.ActivityType

    CASE ActRoutine!

    TraceTreeRoutine ltctrt_rout

    ltctrt_rout = ltct_node

    result += "Enter " + ltctrt_rout.ClassName &

    + "." + ltctrt_rout.name + " " &

    + String(ltctrt_rout.ObjectID) + " " &

    + String(ltctrt_rout.EnterTimerValue) &

     + "~r~n" ltctrt_rout.GetChildrenList(ltctn_list)

...
