             throws java.lang.Exception

********************************************* ** USER CODE of PositiveF goes here *** *********************************************

Specified by:

process in class Unit

Throws:

java.lang.Exception

keepPositiveFrequencies

public static void keepPositiveFrequencies(GraphType input)

init

public void init()

Initialses information specific to PositiveF.

Overrides:

init in class Unit

reset

public void reset()

Called when the reset button is pressed within the MainTriana Window

Overrides:

reset in class Unit

stopping

public void stopping()

Called when the stop button is pressed within the MainTriana Window

Overrides:

stopping in class Unit

saveParameters

public void saveParameters()

Saves PositiveF's parameters.

setParameter

public void setParameter(java.lang.String name,
                java.lang.String value)

Used to set each of PositiveF's parameters. This should NOT be used to update this unit's user interface

updateWidgetFor

public void updateWidgetFor(java.lang.String name)

Used to update the widget in this unit's user interface that is used to control the given parameter name.

getInputTypes

public java.lang.String[] getInputTypes()

Description copied from class: Unit

This method should return an array of the data types accepted by nodes not specified in getNodeInputTypes (e.g. triana.types.VectorType). If no package is specified then triana.types is assumed.

Specified by:

getInputTypes in class Unit

Returns:

a string containing the names of the types allowed to be input to PositiveF, each separated by a white space.

getOutputTypes

public java.lang.String[] getOutputTypes()

Description copied from class: Unit

This method should return an array of the data types output by nodes not specified in getNodeOutputTypes() (e.g. triana.types.VectorType). If no package is specified then triana.types is assumed.

Specified by:

getOutputTypes in class Unit

Returns:

an array of the output types for this unit

getPopUpDescription

public java.lang.String getPopUpDescription()

This returns a brief! description of what the unit does. The text here is shown in a pop up window when the user puts the mouse over the unit icon for more than a second.
