Viewing execution times for nodes in the stream

In the table of node execution times, the columns are as follows. Click a column heading to sort

the entries into ascending o r descending order (for example, to see which nodes have the longest

execution times).

Terminal Node. The identiﬁe r of the branch to which th e n ode belongs. The identiﬁer is the name

of the terminal node at the e nd of the branch.

Node Label. The name of the node to which the execution time ref ers.

Node Id. The unique identiﬁer of the node to which the exe cution time ref ers. This identiﬁer is

generated by the system when the n ode is created.

Execution Time(s). The time in seconds taken to execute this node.

Setting Stream and Session Parameters

Parameters can be deﬁned for use in CLEM expressions and in scripting . They are, in effect,

user-deﬁned variables that are saved and persisted with the current stream, session, or Super Node

and can be accesse d from the user inter f ace as well as through scripting. If you save a stream, for

example, any param eters set for that stream ar e also saved. (This distinguishes them from local

script vari ables, which can be used only in the script in which they are declared.) Parameters are

often used in scripting as part of a CLEM expre ssion in which the parameter value is speciﬁed in

the script.

The scope of a parameter depends on where it is set:

 Stream paramete r s can be set in a s tream script or in the stream properties dial og box, and

they are ava ilab

le to all nodes in the stream. They are displayed on the Parameters list in the

Express ion Build er.

 Sessio n parameters can be set in a stand-alone script or in the session parameters dialog

box. They are available to all streams used in the current se ssion (all streams listed on the

Streams tab in th

e managers pane).
