RE operations - script to Java migration

For the RE operations, not all of the script operations from the Script API are implemented in the Java™ API. Alternative Java code is provided for those script operations that are not implemented in the Java API.

The following RE methods can be achieved by using org.apache.regexp.

Table 1. Script operations and alternative Java code for the RE operations
Script operation	Alternative Java code
buildRE	Org.apache.regexp.RE = new RE(pattern, matchFlags.intValue)
new RE	Org.apache.regexp.RE = new RE(pattern, matchFlags.intValue)
Match	Org.apache.regexp.RE.match(str)
substitute	Org.apache.regexp.RE.subst(substrituteIn, substitution);
