Examples of org.htmlparser.lexer.PageIndex

org.htmlparser.lexer.PageIndex
A sorted array of integers, the positions of the first characters of each line. To facilitate processing the first element should be maintained at position 0. Facilities to add, remove, search and determine row and column are provided. This class provides similar functionality to a Vector but does not incur the overhead of an Integer object per element.
