emolib.util.printer
Class Printer

java.lang.Object
  emolib.util.proc.TextDataProcessor
      emolib.util.printer.Printer

All Implemented Interfaces:

Configurable, DataProcessor

public class Printer
extends TextDataProcessor

The Printer class provides a device to output the content of the data flowing in the processing pipeline.

The Printer can be configured through the XML configuration file to output various types of information. Its inclusion is not restricted to any part of the processing chain. The idea is that the Printer enables the check-out procedure to be carried out easily and securely thus being a trustful monitor for the application.

The different configuration parameters are listed as follows:

• echo_emotional_words: prints the emotional words that the pipeline contains.
• echo_modifiers: prints the modifiers and their values.
• echo_nouns: prints the nouns in the text.
• echo_number_of_words: prints the number of words pertaining to a paragraph that are introduced into the system.
• echo_stems: prints the stem of the emotional words in the text.
• echo_stemmed_synonyms: prints the stemmed synonyms of the emotional words in the text.
• echo_synonyms: prints the synonyms of the words with emotional content.
• echo_word_class: prints the class of word of each word in the text.
• echo_word_pos: prints the POS tag of each word in the text.

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 Printer.

Specified by:

initialize in interface DataProcessor

Overrides:

initialize in class TextDataProcessor

applyPrinting

public void applyPrinting(TextData inputTextDataObject)

Method to perform the printing process.

Parameters:

inputTextDataObject - The TextData object to process.
