Constructor Detail

MaxTraceFunction.Double

public MaxTraceFunction.Double(IDoubleSource source,
                               int valueID)

Create a basic statistic probe on a IDblSource object.

Parameters:

name - Name of the statistic object.

source - The IDblSource object.

valueID - The value identifier defined by source object.

MaxTraceFunction.Double

public MaxTraceFunction.Double(java.lang.Object source,
                               java.lang.String valueName,
                               boolean getFromMethod)

Create a basic statistic probe on a generic object.

Parameters:

name - Name of the statistic object.

source - A generic source object.

valueName - The name of the field or the method returning the variable to be probed.

getFromMethod - Specifies if valueName is a method or a property value.

Method Detail

applyFunction

public void applyFunction()

Read the source values and update statistics.

Overrides:

applyFunction in class MaxTraceFunction

getDoubleValue

public double getDoubleValue(int valueID)

Return the result of a given statistic.

Parameters:

valueID - One of the F_ constants representing available statistics.

Returns:

The computed value.

Throws:

java.lang.UnsupportedOperationException - If the given valueID is not supported.

getLastValue

public double getLastValue()

Return the last double value read from the source object.

Returns:

A double value collected at the last reading operation.

getMax

public double getMax()

Return the current max value.

Returns:

The maximum value.
