Other Notes

• The escape character \ can be used when necessary to escape the following characters: $ , { }

warning

It is possible to cause StackOverflowErrors if your nested variables result in a recursive loop (e.g. the environment variable 'MYPROPERTY' has the value '$E{MYPROPERTY}'). So don't do that!

• As a general rule, this class tries to be as efficient as possible by not creating new strings when not needed. For example, calling the resolve method on a string that doesn't contain variables (e.g. resolver.resolve("foobar")) will simply be a no-op and return the same string.
