public abstract class Report
extends java.lang.Object

Abstract superclass for all reports. All settings defined in this class can be used for all Report classes. Some reports don't implement intervalled reports (INTERVAL_SETTING) and will ignore that setting. Most of the reports implement warm up feature (WARMUP_S) but the implementations are always report specific.

Constructor Detail

Report

public Report()

Constructor. Looks for a className.output setting in the Settings and if such is found, uses that as the output file name. Otherwise scenarioname_classname.txt is used as the file name.

Method Detail

init

protected void init()

Intializes the report output. Method is called in the beginning of every new report file. Subclasses must call this method first in their own implementations of init().

newEvent

protected void newEvent()

This method should be called before every new (complete) event the report logs. If the report has no meaningful use for multiple reports, the call can be omitted (then only single output file will be generated)

write

protected void write(java.lang.String txt)

Writes a line to report using defined prefix and out writer.

Parameters:

txt - Line to write

See Also:

setPrefix(String)

format

protected java.lang.String format(double value)

Formats a double value according to current precision setting (see PRECISION_SETTING) and returns it in a string.

Parameters:

value - The value to format

Returns:

Formatted value in a string

setPrefix

protected void setPrefix(java.lang.String txt)

Sets a prefix that will be inserted before every line in the report

Parameters:

txt - Text to use as the prefix

getScenarioName

protected java.lang.String getScenarioName()

Returns the name of the scenario as read from the settings

Returns:

the name of the scenario as read from the settings

getSimTime

protected double getSimTime()

Returns the current simulation time from the SimClock

Returns:

the current simulation time from the SimClock

isWarmup

protected boolean isWarmup()

Returns true if the warm up period is still ongoing (simTime < warmup)

Returns:

true if the warm up period is still ongoing, false if not

addWarmupID

protected void addWarmupID(java.lang.String id)

Adds a new ID to the warm up ID set

Parameters:

id - The ID

isWarmupID

protected boolean isWarmupID(java.lang.String id)

Returns true if the given ID is in the warm up ID set

Parameters:

id - The ID

Returns:

true if the given ID is in the warm up ID set

getSettings

protected Settings getSettings()

Returns a Settings object initialized for the report class' name space that uses "Report" as the secondary name space.

Returns:

a Settings object initialized for the report class' name space

done

public void done()

Called when the simulation is done, user requested premature termination or intervalled report generating decided that it's time for the next report.

getAverage

public java.lang.String getAverage(java.util.List<java.lang.Double> values)

Returns the average of double values stored in a List or "NaN" for empty lists.

Parameters:

values - The list of double values

Returns:

average of double values stored in the List in a formatted String

getIntAverage

getMedian

public java.lang.String getMedian(java.util.List<java.lang.Double> values)

Returns the median of double values stored in a List

Parameters:

median of double values stored in the List or "NaN" for empty lists.

getIntMedian

public int getIntMedian(java.util.List<java.lang.Integer> values)
