Viewing executiontimes 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 or descending order (for example, to see which nodes have the lo ngest
execution times).
TerminalNode. Thei dentifier of the branch to which the node belongs. The iden tifier is the name
of the terminal node at the end of the branch.
NodeLabel. The name of the node to which the execution time refers.
NodeId. The unique identifier of the node to which the execution time refers. This identifier is
generated by the system when the node is created.
ExecutionTime(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 SuperNode
and can be accessed from the user interface as well as through scripting. If yo u save a stream, for
example, any parameters set for that stream are also saved. (This distinguishes them from local
script variables, which can be used only in the script in which they are declared.) Parameters are
often used in scripting as part of a CLEM expression in which the parameter value is specified in
the script.
The scope of a parameter depends on where it is set:
Stream parameters can be set in a stream script or in the stream properties dialog box, and
they are available to all nodes in the stream. They are d isplayed on the Parameters list in the
Expression Builder.
Session parameters can be set in a stand-alone script or in the session parameters di alog
box. They are available to all streams used in th ec urrent session (all streams listed on the
Streams tab in the managers pane).
