public class TextReplacement
extends java.lang.Object

TextReplace is a simple means to replace all occurances of a string, with another string using a regular expression and a TextResolver. The regular expression must contain one group, and the resolver will be passed the value of the group, and it should return the replacement value or null. This differs from a normal String.replaveAll() in that the replacement value, in this case, is dynamic based on the parsed group value. For example if you have a String like, "where field1=:value1 and field2=:value2" with a regex of ":([a-z])", then the TextResolver will be passed 'value1' and 'value2' and be expected to resolve a potentially different value for each.
