Statistical views

The Statistical views display a variety of details about a profile session. There are four statistical views, each one displaying results for a selected type of object:

Package statistics
Class statistics
Method statistics
Instance statistics

Common Displays

The following symbols are common to all Statistical views.

The delta icons and indicate that there is a change in the numeric value (increase or decrease respectively) for that particular cell since the last time the table was refreshed.
The diamond indicates new occurrences since the last time the Refresh Views button was pressed.

Common Controls

The following controls are common to all Statistical views.

Toolbar controls

: Opens the source of a selected item.
: Shows the cumulative time as a percentage instead of seconds.
: Shows the change in each numeric column since the last refresh.
: Prints a column of data.

Filtering

The statistics views provide filtering based on name. Use the Filter field to specify a string pattern.

Click the title of a column to sort it. Click the title of the column again to sort it in reverse order. The title of the column is prefixed with < if the column is sorted in ascending order or with > if it is sorted in descending order.

Columns can be hidden or shown.

Displays in each view

The displays available and what they contain depends on what view is selected and, within the view, what object is selected. Objects are visible only in those views where their information is useful.

The statistics available in each view are summarized in the table below.

	Package statistics	Class statistics	Method statistics	Instance statistics
	Allows selection of package and class objects only	Allows selection of class and method objects only	Allows selection of method objects only	Allows selection of class objects only, and only if the collection of instance level information has been enabled
Total Instances The total number of instances that had been created of the selected package, class, or method.	Accumulated by package	Accumulated by class	Not available	Count
Live Instances The number of instances of the selected package, class, or method, where no garbage collection has taken place.	Accumulated by package	Accumulated by class	Not available	Count
Collected The number of instances of the selected package, class, or method, that were removed during garbage collection.	Accumulated by package	Accumulated by class	Not available	Count
Total Size The total size (in bytes) of the selected package, class, or method, of all instances that were created for it, including whatever has been removed through garbage collection.	Accumulated by package	Accumulated by class	Not available	Size
Active Size The summed size of all live instances.	Accumulated by package	Accumulated by class	Not available	Size
Base Time For any invocation, the base time is the time taken to execute the invocation, excluding the time spend in other methods that were called during the invocation.	The summed base time for the classes in the package	The summed base time for the methods in the class	The time spent executing a given method	Time
Average Base Time	Not available	Not available	??	Not available
Inherited Base Time Similar to the base time spent in the selected package or class although it does include the time spent in other (inherited) methods that were called during the invocation.	The summed base time for the classes in the package	The summed base time for the methods in the class	Not available	Time
Cumulative Time For any invocation, the cumulative time is the time taken to execute the time spent in methods called by the invocation.	The summed cumulative time for the classes in the package	The time spent executing the methods in the class	The time spent executing the given method.	Time
Inherited Cumulative Time Similar to the cumulative time of the selected package or class, although it also includes the time spent in other (inherited) methods that were called during the invocation.	The summed cumulative time for the classes in the package	The time spent executing the methods in the class	Not available	Time
Calls The number of calls made by a selected method.	Not available	Accumulated by class	Count	Not available
Inherited Calls The number of calls made by a method and by its inherited methods.	Accumulated by package	Accumulated by class	Not available	Count

Controls in each view

Here is a description of controls, indicating their availability in the views.

	Package statistics	Method statistics	Instance statistics
Refresh Views To update all Profiling and Logging views.
Choose Columns To select which columns should be hidden and visible. (See descriptions of columns above.)
Show Method Invocation (if available) To open the Method Invocation view for the selected method.	Not available		Not available
Show Object References (if available) To show the Object References table for the selected package or class.		Not available
Open Source To open an editing view containing the selected source code. The method, class, or package must be in the workbench.
