BBjString

Description

In BBj 7.0 and higher, the BBjString object defines an object-oriented interface to traditional BBx strings. It implements most of the methods defined by java.lang.String. This API is primarily designed to facilitate interaction with Java libraries.

Creation

BBjAPI > BBjString

All string values created in BBj are BBjStrings. To access BBjString methods, copy a BBj string value to an object variable:

string! = "Hello world"
print string!.length()
