BuildWords Method

Summary

Build a list of the words found in the document page.

Syntax

Java

C++

public void BuildWords()

Public Sub BuildWords()

public:  
   void BuildWords()

public void buildWords()

Remarks

The text words are created from the characters found in the document based on the IsEndOfWord returned by document parsing engine. Whenever an "end of word" is found, the last set of characters are grouped together and stored as an item in the Words list. This is not performed automatically, instead, you must call BuildWords to populate the Words list from the Characters.

The following explains how this method works. If the page text consists of the following string Hello World, then the text parser engine will populate Characters as follows (ignoring Bounds):

Index	Code	IsEndOfWord	IsEndOfLine
0	H	false	false
1	e	false	false
2	l	false	false
3	l	false	false
4	o	true	false
5	W	false	false
6	o	false	false
7	r	false	false
8	l	false	false
9	d	true	true

BuildWords will loop through each character till an item with IsEndOfWord equals to true is reached, it will then create a word from the characters found so far, in this case from index 0 to 4. The characters are combined into DocumentWord.Value (The string Hello) and the union of these characters position and location (DocumentCharacter.Bounds) are set into DocumentWord.Bounds. The first index (0) and the last index (4) are set into DocumentWord.FirstCharacterIndex and DocumentWord.LastCharacterIndex.

The method then continues to the next character (index 5) and repeat the operation, this time using indices 5 and 9 and the result is DocumentWord with Value set to 5 and LastCharacterIndex set to 9.
