Class StringTransform

java.lang.Object

prajna.text.StringTransform

public class StringTransform
extends java.lang.Object

Transforms strings according to a pattern. The transformation pattern defines a series of transformations. If the transform pattern is not null, the transformations are applied sequentially to the field string. The transformations are the following:

• +term: append term to the end of the transformed string
• -term: remove every instance of term from the transformed string
• ?term: select only the words immediately preceding term, and concatenate them together, separating by a space
• %u, %l, or %c: convert the entire string to uppercase, lowercase, or camelcase respectively
