emolib.statistic
Class Statistic

java.lang.Object
  emolib.util.proc.TextDataProcessor
      emolib.statistic.Statistic

All Implemented Interfaces:

Configurable, DataProcessor

Direct Known Subclasses:

ArithmeticMean

public abstract class Statistic
extends TextDataProcessor

The Statistic abstract class defines the general class to perform the statistical calculations.

At this point, the emotional words should already have their correspondent emotional dimensions. The purpose of this class is to compute a determined statistic and use it as an estimator of a population parameter which is not directly observable. These parameters should be available for all the levels of the data structure (sentence and paragraph levels).

Method Detail

register

public void register(java.lang.String name,
                     Registry registry)
              throws PropertyException

Description copied from interface: Configurable

Register my properties. This method is called once early in the time of the component, shortly after the component is constructed. This component should register any configuration properties that it needs to register. If this configurable extends another configurable, super.register should also be called

Specified by:

register in interface Configurable

Overrides:

register in class TextDataProcessor

Parameters:

name - the name of the component

registry - the registry for this component

Throws:

PropertyException

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException

Description copied from interface: Configurable

This method is called when this configurable component has new data. The component should first validate the data. If it is bad the component should return false. If the data is good, the component should record the the data internally and return true.

Specified by:

newProperties in interface Configurable

Overrides:

newProperties in class TextDataProcessor

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.

getData

public Data getData()
             throws DataProcessingException

Obtains the TextData from the previous module, processes it and makes it available to the rest of the text processing chain.

Specified by:

getData in interface DataProcessor

Specified by:

getData in class TextDataProcessor

Returns:

The next available Data object, returns null if no Data object is available.

Throws:

DataProcessingException - If there is a processing error.

initialize

public void initialize()

Method to initialize the Statistic.

Specified by:

initialize in interface DataProcessor

Overrides:

initialize in class TextDataProcessor

applyStatistics

public abstract void applyStatistics(TextData inputTextDataObject)

Method to perform the statistical process.

Parameters:

inputTextDataObject - The TextData object to process.
