public class WAISWordLiteral
extends ExpNode
implements SourceNode
An ExpNode that represents a word literal in a WAIS query expression. Each WAISWordLiteral has no children and two properties soundex - a boolean indicating whether this token should be matched using soundex. literal - the String token.

Constructor Index

o WAISWordLiteral(Query, boolean, String)
Create a new WAISWordLiteral

Method Index

o GetLiteral()
Return the string that is the word literal.
o RankBy(Document)
This is a slot to do some primitive ranking on this sub-tree.
o Soundex_p()
Predicate determining wether this token should be matched using soundex.
o Unparse()
Return the string representation of the subtree rooted at this word literal
