Class GString

    java.lang.Object
      groovy.lang.GroovyObjectSupport
          groovy.lang.GString

All Implemented Interfaces:
  Comparable

    class GString
    extends GroovyObjectSupport

Represents a String which contains embedded values such as "hello there ${user} how are you?" which can be evaluated lazily. Advanced users can iterate over the text and values to perform special processing, such as for performing SQL operations, the values can be substituted for ? and the actual value objects can be bound to a JDBC statement. The lovely name of this class was suggested by Jules Gosnell and was such a good idea, I couldn't resist :)
