TraceViewer provides various options for setting up filtering.
+In some cases, it may also be necessary to use an external filter
+application to modify the results. For instructions,
+see Using an external filter application.
+
+
Basic options
+
You can create new filter rules in the basic Rules dialog, as for
+other items. For instructions, see Setting up rules
+and filters.
+
+
To set filtering-specific options:
+
+
After the rules are defined, select one or more of them from the tree.
+
Select either Hide or Show, to make the selected rules visible
+on the tree.
+
Select either the OR or AND operator:
+
+
OR means that if a trace hits just one rule, it is applied.
+
AND means that the trace must hit all the selected rules for it to be
+applied.
+
+
+
To take the selected rules to use, click Apply.
+
+
+
Creating rule statements
+
You can make also more complicated filtering rules by setting advanced options. The point
+is to make an effective and reasonable filter rule set, which will then be
+used when filtering traces.
+
A rule set is written the form of a statement such as this:
+
(rule AND rule2) OR (smallRule AND NOT filterRule)
+
where traces are included or excluded based on this criterion.
+
Tip: You can also type the rule set statement manually into
+the text field.
+
To set advanced options:
+
+
In the Filter Rules dialog, click Advanced.
The Advanced
+Filter Rules dialog is displayed, showing the basic rules already created.
+
+
To start creating a new rule set, click Start Set.
An opening
+parenthesis ( is inserted into the text field to indicate the beginning.
+
To edit the rule set, select rules from the tree and combine them with
+each other by clicking any of the following buttons:
+
+
AND: Indicates logical AND. Is used between two rules or rule sets
+and means that both rules / sets will have to hit the rule for it to be true.
+
+
OR: Indicates logical OR. Is used between two rules or rule sets
+and means that either rule / set will have to hit the rule for it to be true.
+
+
NOT: Indicates logical NOT. Is used before a rule or rule set.
+Indicates that the rule / rule set after the NOT can not hit the rule for
+it to be true.
+
+
The Back button removes the last word from the text field,
+starting from the caret position.
+
(Optional) To quickly add all the rules from a group to the set, click
+the group name on the tree.
From the pop-up, select OR or AND. After choosing,
+all the rules from this group are added to the text field, separated by the
+selected logical operation.
+
Click End Set to insert a closing parenthesis ) into the field.
+Note: TraceViewer automatically checks that the rule is reasonable and
+well-formed, that is, contains as many start brackets as end brackets. The
+following is an example of a reasonable filter rule set that is correct and
+ready to be applied:
+
(Optional) To hide or show a trace that hits this filter rule, change
+the value of Show and Hide selection as needed.
+
Click OK to save the rule set.
+
+
+
+
To clear the rule text field and start creating a new one, click Clear
+.
