Class RegexRenamer

java.lang.Object
  org.javagen.agile.core.util.RegexRenamer

public class RegexRenamer
extends Object

Itererates through a list of regular expressions and applies a replacement string when a match is found.

Currently only applies the first match found, ingnoring any remaining regex's in the list.

Regex and replacePatterns can be set as a single property string or added individually by calling addReplacementPattern.

For example to add a regex to remove 'Fk' & 'Pk' suffixes from a name such as 'PersonPk', you can call either:

addReplacementPattern("^([a-zA-Z]+)(Fk|Pk)$", "$1")

or

setRegexReplacePairs("^([a-zA-Z]+)(Fk|Pk)$>$1")

As a single string property the general form of the list is: regex1>replace1,regex2>replace2,...

The replacePattern can be any text interspersed with regex group replacement holders of the form $n, for example: text$1text$3text
