Interface WordFinder

All Known Implementing Classes:

AbstractWordFinder

public interface WordFinder

An interface for objects which take a String as input, and iterates through the words in the string.

When the object is instantiated, and before the first call to next() is made, the following methods should throw a WordNotFoundException:
current(), startsSentence() and replace().

A call to next() when hasMoreWords() returns false should throw a WordNotFoundException.

Word	next() This method should return the Word object representing the next word in the iteration (the first word if next() has not yet been called.)
void	replace(java.lang.String newWord) This method should replace the current Word object with a Word object representing the String newWord.
void	setText(java.lang.String newText) This method resets the text through which the WordFinder iterates.
boolean	startsSentence()

Method Detail

getText

public java.lang.String getText()

This method returns the text through which the WordFinder is iterating. The text may have been modified through calls to replace().

Returns:

the (possibly modified) text being searched.

setText

public void setText(java.lang.String newText)

This method resets the text through which the WordFinder iterates. It must also re-initialize the WordFinder.

Parameters:

newText - the new text to search.

current

public Word current()

This method should return the Word object representing the current word in the iteration. This method should not affect the state of the WordFinder object.

Returns:

the current Word object.

Throws:

WordNotFoundException - current word has not yet been set.

hasNext

public boolean hasNext()

Tests the finder to see if any more words are available.

Returns:

true if more words are available.

next

public Word next()

This method should return the Word object representing the next word in the iteration (the first word if next() has not yet been called.)

Returns:

the next Word in the iteration.

Throws:

WordNotFoundException - search string contains no more words.

replace

public void replace(java.lang.String newWord)

This method should replace the current Word object with a Word object representing the String newWord.

Parameters:

newWord - the word to replace the current word with.

Throws:

WordNotFoundException - current word has not yet been set.

startsSentence

public boolean startsSentence()

Returns:

true if the current word starts a new sentence.

Throws:
